Bed Bugs
Bedbugs – what's the score?
Lice wall, floors errors, crimson ramblers, bugs Norfolk Howards, mahogany floors, etc, etc. The humble bed bug (Cimex
lectularius) has won a place in the folk world and is universally reviled. Many years attack in the United Kingdom had
reduced the population considerably, but recently this annoying pest has had a resurgence, both in terms of numbers
and in several cases of pesticide tolerance. Why? Let's start with a review of the pest and its habits.
As the man moved from hunter-gatherer to life in urban settlements, many insects took advantage of this localized
situation. Initially, flies and beetles were attracted to the storage areas and food preparation. The bugs moved in as a human being
home improvement and became more permanent. Are closely related to the error of bats (Cimex pilosellus) and probably
first became associated with men when they lived in caves in Africa.
Human beings (much like now) sought a blood meal, while they slept on the floor of the cave. The
errors to locate their hosts by sensing their body heat and carbon dioxide released in respiration and through
your skin. Interestingly, there is still a sort of bed bug (Leptocimex boueti) still feeds on the blood of humans
and bats in West Africa.
As civilization evolved, the bed bug became our bed partner, entering our homes in numbers growing. Sanitation
and grooming is offered as a defense against lice and other parasites from the body. In 1602, Ulysses Aldrovandi, a
renowned social observer, reported that bed bugs were much more common in the homes of the poor in the
rich because the rich have the means to keep their homes clean than those of the poor. In late 1800, bed bugs
were considered as probably the most serious urban pest. Commercial pest control companies began to form the largest
cities across Europe at this time. His preparations ranging from chemicals that would be a mile from today, several
still recognize and use today – mercuric chloride in alcohol was considered an excellent treatment for bedbugs
and pyrethrum and rotenone were beginning to arrive from the East.
In more recent times, the success of pesticides such as organophosphates and pyrethroids, has meant
large-scale eradication of populations bugs. Now we realize that the dirty house is not a prerequisite for the activity of bugs,
but it is believed that the unfortunate decline in social norms some areas of town, along with increased
foreground full of communities HMO (houses of multiple occupancy, student accommodation, bed sits and does not forget
down-and-outs) have been bed bug populations increased considerably.
So what exactly is a bed bug? These insects are members the order Hemiptera, the bugs, including errors
that attack house plants and pond skaters live on the surface of the water.
The bed bug has a simple or incomplete metamorphosis. Pairing is a rough affair, with men actually puncture
female abdomen to inject sperm directly (a process known as "traumatic" insemination for obvious reasons!). A female
can lay up to 200 eggs for about two months. There are five nymphal stages having from 35 to 150 days to go,
depending on conditions. Adults can survive long periods in unoccupied houses or furniture in the store. In
desperation, which can survive in other species, including birds, sparrows, rats, mice and guinea pigs (which may explain
Some infestations continued long-term). Adults who are well fed then you can withstand long periods of famine – timelines
almost a year and a half have been registered.
nymphal instars take about three minutes to take a blood meal, but adults need more than ten minutes to swell.
Mouthparts are adapted to form two pairs of stilettos that puncture the skin. The foreign partner is provided with barbed
seen in the skin and the inside pair to form two tubes, one for suck blood, and one for injecting saliva containing
an anticoagulant. An adult can be quite congested from 6 to 8 mm long.
For many, the sting painless, but some can be detected immediately. A typical red "rash" is left by the insect,
caused by an allergic reaction to saliva. The bite site (s) is very useful for a pest controller in the diagnosis of
biting species. flea bites are most commonly in the leg or ankle, while bug bites often in the face, neck
arms or hands, and from time to time around the waist.
Where do they live? In the urban ecosystem, there are three main components of humans and nonhumans and
physical structures. The habitat consists of the settlements known as "Anthropobiocoenosis." Probably
the largest ever used the word Pest Control News, the long term, the environmental has been
completely changed by man. It may even be sub-divided into "peri" habitats, which are outside homes,
and "national" habitat found inside the home. The bed bug has invaded most areas of the latter category,
but mainly the areas that dream. This is because the time it takes to have a blood meal, and unless it is a
couch potato, humans do not feel still long enough for this to happen in the living room!
Control of bed bugs has always been relatively simple, although often a lot of and a thorough search
treatment or number of treatments needed. However, in recent months, reports have appeared in national
release of "super pests" from "resistant mutant bed bugs." This situation requires an explanation.
It is known that the incidence of insect the bed is on the rise, especially in London and in some of the campuses and
cities like Cambridge. It is also known by a number of pest controllers that several populations are becoming very
difficult to treat successfully. Words such as "pesticide-resistant" are therefore word of mouth. This term is not guaranteed.
resistance to truth is a biological term, which means a population over time has become "immune" the effects of
pesticides. This can only be given by adult survivors and their children and takes time and generations. The
cases reported in the press are more likely to be those of "tolerance" on the bed bugs are able to tolerate
pesticides and survive. (The children of survivors, therefore be "resistant").
Like all treatments in a given product does not help the selection of a pesticide from another asset group
ingredients if often the answer. Currently, infestations that are causing some difficulties seem to be able to tolerate
Pyrethroids, and some carbamate are also tolerant.
Nigel Binns, Biologist Killgerm Chemicals Ltd., commented: "We are receiving a number of phone calls, where
are experiencing technical difficulties in controlling infestations of bed bugs. If used pyrethroids and / or
carbamate, a return to use organophosphate pesticides usually does the trick. The disadvantage of this is that
are often some "bad smell", so that the client must be informed. Organophosphate pesticides that have been approved for
its use as a public health products are perfectly safe in such situations, provided the following technical to label
recommendations. "
Finally, the bug has predators. T. Pergande, a Union soldier in the American Civil War, reported that Pharaoh
ants (Monomorium pharaonis) bugs attacked and butchered in a Mississippi infested quarters – maybe this
is a new form of biological control could choose to hire. Two infestations for the price of one!
Cockroach and dust mites
Many allergies are well known and understood, but allergies to insects and mites are still being examined. A 1997 study,
supported by the U.S. National Institute of Allergy and Infectious Diseases (NIAID) demonstrated conclusively that
combination of cockroach allergy and exposure to insects is a major cause of asthma-related illness and
hospitalizations among U.S. children areas of downtown.
"Some of the most vulnerable our citizens, children in the poorest neighborhoods of our large cities, suffer
disproportionate share of asthma, "says Anthony S. Fauci, MD, director of NIAID in the report. "Allergy and exposure to
cockroach allergen clearly play an important role in the alarming rates of illness related to asthma among children. "
"Reducing exposure to cockroach allergen, as part of a multifaceted approach to asthma management, can be a cost
effective way to reduce the burden of this serious disease, "says Daniel Rotrosen, MD, acting director of NIAID
Division Allergy, Immunology and Transplantation. "Simple and relatively inexpensive interventions that have been explored
into NCIC, such as patient education, the roach traps and insecticides safe for children, are potentially important. "
The first phase of five years studied 476 of these children. The Researchers measured levels of cockroach, dust mite and cat
allergens in homes of children, and was determined by skin prick tests that 37 percent of children who were allergic to
cockroaches, 35 percent to dust mites, and 23 – percent to cats. The researchers then assessed severity
childhood asthma over 12 months.
They found that children who were allergic to cockroaches and exposed to high levels of allergen cockroach
hospitalized for their disease 3.3 times more often than children who were allergic but not exposed to high levels of
allergen cockroaches, or children who were exposed to high levels of cockroach allergen, but were not allergic. Children
who were allergic and very exposed to cockroach allergen also missed school more often, they need almost twice
the largest number of unscheduled medical visits related with asthma, and suffered through most nights of lost sleep.
Moreover, the activities of adults who cared for these children were frequently interrupted. The researchers also collected
dust samples from each child's room with a handheld vacuum to measure the level of each allergen. While
Most Room had detectable levels of all allergens, 50.2% contained induce high levels of cockroach allergen disease
compared with 12.6% of rooms with high levels of cat allergen and 9.7% with high levels of dust mite allergens.
Even when families do all things at home, however, "… The biggest problem with cockroaches, in some cases, is in the
schools themselves, "says Dr. Jean Hanley-Lopez, Los Angeles Breathmobile Director. "At the heart of the city schools of Los Angeles, students
have a high level of exposure to cockroaches, "she says," but I'm sure that the school district is not even aware of how big a problem
This is for students with asthma. "
Dr. Thomas Platts-Mills, one of the researchers NIAID, mentioned several difficulties. "People do not always understand that
who have allergies to cockroaches. Also cockroach dust dispersed "throughout the home, "so it is difficult to remove. Sprays
do a lot of patients with asthma is worse, "Platts-Mills adds," and you can use all bait traps you want, but will not work
If cockroaches have a food supply. "
"It's good to have ambitions to reduce cockroaches" concludes, "but we need a better understanding of how
to do so. "Dr. Richard Evans, an asthma specialist at Children's Memorial Hospital Chicago agrees: "The only thing
to do is help people get rid of cockroaches. "
Dust mite allergy is an allergy a microscopic organism that lives in the dust found in all dwellings and domestic
workplaces. People are slowly recognizing that mites dust and their droppings are perhaps the most common cause
asthma and allergic rhinitis.
House dust is not a single substance, but a cocktail of materials potentially allergenic. It may contain fibers of different
types of fabrics, feathers and other stuffing materials, dander from cats, dogs and other animals, bacteria, mold spores,
fragments of plants and insects and other particles characteristic of an individual building. House dust also contains thousands of
microscopic mites that live in bedding, upholstered furniture, carpets etc. They thrive in summer and tend to die
winter. However, in warm and humid, such as a home with central heating, a hospital or office, following
thrive.
Each mite produces about twenty pills a day of waste, each with a small quantity of one of the most dangerous
chemicals known to science. Not only is the allergen of house dust mites, the usual cause of babies and toddlers
become asthmatic, it is also more common in a long list of irritants that cause asthma so that existing airway
symptoms.The constant presence of the droppings of dust mites in the air inside homes is the lungs of asthmatics are sensitive to
all other factors that trigger asthma symptoms. If patients can avoid the allergens from dust mites for a few months, then
usually other factors loses much of its power.
Because mites are so small, its regulation of body water is essential. As a result, droppings they produce are very dry. The
average population per gram of dust is believed to be 100 to 500, but may be in the thousands. Females laying eggs
Mites population may increase 25 to 30 every three weeks. Mites are equipped with sticky pads on the ends of their
feet, so they are able to dig deep in the fibers of the carpet and furniture in which move forward and are able to survive the vacuum.
Proteins in dust mite feces, called Der P1 and Der F1, are major instigators of allergic reaction. When these
Floating pellets are inhaled, can cause problems in a person allergic to dust mites. Even after the death of the mite fecal particles
stay at home, and the mite of the disintegration of the body parts are still in the air and allergens easily.
Although the environment is not free of dust mites, there are specific steps you can take to reduce the number of such
creatures in their home. Many of these stories emanating from the old, but have their basis in fact:
Mattresses, box springs and pillows should be encased in non-allergenic, plastic sheeting zip. The rack must be
covered with tape. Wipe with a damp cloth or vacuum weekly. If more than one bed in a room, each one
mattress should be enclosed. If bunk beds are used, the allergic child should sleep in the bunk above. Avoid using canopy
beds.
Use blankets Washable, extends and polyester or Dacron pillows. Avoid feather pillows, duvets and down comforters, wool
blankets and chenille spreads. Wash clothing bedding frequently in hot water (above 60 degrees Celsius). Do not use a
washing of the economy such as dust mites survive in warm water, and just ended mites to clean!
Ants
Understanding Ant Music
The ability to communicate through media infochemical, including pheromones, is at its highest level among the insects that live
in homogeneous communities – the social insects. Ants in particular is distinguished by numerous exocrine glands
and various chemicals secreted as information links between their groups.
The largest of the Ants have eyes located about 5 mm from the ground, while the eyes are smaller than 1 mm above the
ground and are unable to see beyond the height of 5 mm. The view then, is not its strongest point. Ants
bees evolved and developed acute sense of smell, enabling them to seek food, even
darkest situations. Ant senses environmental chemicals such as odors or volatile matter through physical
contact through their antennae. Then reacts according to the chemical information they transmit.
Chemical signals for species recognition
Insect species consists entirely of men and women with a male and a female of each species to reproduce. Sex
pheromones facilitate meetings however mating, how to determine an insect belonging to the pair potential
same species?
Dr. Ryohei Yamaoka, Institute of Technology Kyoto has evaluated the infochemicals important role in various
the identification of ants and their dependence on their fascinating world. The team cuticular waxes sampled,
including oil, more than 500 species of insects including ants. They found that the composition of
these substances is different for all insect species in the sample. They also discovered what happens when two ants
different species found and fight savagely. Only when the antennae of an ant actually touches the body of his opponent
they begin fighting. No matter how closely the two-pass, unless the antenna touch the body the other, not
fighting will occur. The ants do not recognize their opponents by a vision, but no volatile chemicals in their bodies and
also seem to confirm the membership of the same species by the detection of hydrocarbons equals the same way.
Different species of ants can live together
To live together, the different species should change its prior recognition of cohabitants as belonging to
different species. Slave-maker ants (Polyergus samurai) invade the nests of ants on the hill called black (Formica japonica) or
Black forest ants (Formica sp.) Live, attack and steal pupae and cocoons of them and take their loot
own nest. They attend to the pupae and cocoons until they hatch and feed the queens' eggs manufacturer of slaves ". In
the nest, the ants keep slaves manufacturer of productive activity. They walk about idly causing ants to feed slaves.
The team Dr. Yamaoka shows cuticular hydrocarbons of two species of ants living in harmony in the same nest
As mentioned above, and found that the slave maker ants just can synthesize its own natural oil
species and receive the cuticular hydrocarbons of ants holding slaves through body contact. For Consequently, the slave
maker ants take the same oil that the ants in his slave and thus chemically camouflaged, provision
recognizable as cohabitants of the ants in his slave.
The signals that allow ants to identify colleagues in the same nest
The ability of discrimination chemistry of the ant is so great that it can distinguish not only different species of ants, but ants
from different nests (colonies). Cohabitants of the same children are usually nest of the ant queen herself and sharing
the same relationship. However, other ants, including those of the same species, they share common parentage living
different nests. Instead, they are intense rivals, competing for common food sources.
Ants from a nest as it is believed that the use of individual odors or group characteristic of the nests they inhabit, although
composition of the chemicals involved remains undetermined. However, the composition of hydrocarbons, acting
as a sign of recognition of the species should be identical between the residential and visiting ants because they are members of the
same species … you might think.
The tests took place team produced interesting results. The profiles of hydrocarbon compounds showed a variety of
a group ant colony to another, or were different in each type of ant test. There was also a diversity of ants
queen-less nests. But the samples of the ants in the same nest with a queen were identical. This is because the queen
ants attract nearby workers around by a pheromone. As they approached, workers to initiate physical contact.
Therefore, cuticular hydrocarbons are exchanged between a swarm of individual ants, which leads to consistency chemical
ant in the same colony.
Grooming
Grooming also plays an important role in "spreading" the same oil between ants the same colony. It uses two
methods. One of them is to remove the cuticular hydrocarbons of the couple to lick, then store them in a special gland. The
other is to segregate them from the gland itself for use in coating and the preparation of his own body.
Psocids
Psocids
"Sosids" as the correct pronunciation is, they are booklice and more than 3000 species of them are found throughout the
world but less than 50 are associated with human activities, including food storage and processing. However, their
importance as pests has increased in the last 35 years has been a matter of considerable interest to the Society
Technology of Food Hygiene, which eventually led to sponsor a survey of its members.
The results were published in 1984, but helped define the problem, stressed the need for further
research questions many of them still remain unanswered.
Psocids are widely distributed and usually favor dark places. They infest domestic installations, stores of raw materials,
manufacturing facilities, distribution and retail, museums have also been infected and can be a wide variety of products
suspected infection, including those that are animal and plant origin, including flour-based materials.
A four-time problem
Discomfort – Psocids are a nuisance in the industry because they interfere with the production and threaten the integrity of
products, thus reducing the quality and nature of healthy food.
They are typically associated with newly completed houses – wet building materials, plaster, etc, promoting the growth of
mold in which the insect feeds. They are also taking place in the food cupboards in which infest cereal, flour,
sugar, sauce thickener, etc..
Direct damage to power – psocids not usually associated with damage caused by feeding activities, but directly
damage to goods is possible and particular problems may be experienced when valuables such as furs,
books, etc., are infested.
The transmission of microorganisms – The microorganisms and their spores can survive passage through the gut and psocids
may be carried on the surface of their bodies. Psocids can therefore, responsible agencies broadcast, or even
pathogens.
Health hazard "There is evidence that psocids are vectors of disease. However, they can eat tapeworm eggs
and the port of larvae and thereby act as intermediate hosts of parasites. However, there is increasing evidence
that insects can be a source of allergens environmental. The main impact of infestations in homes psocids considered
and psychological, with reactions that are sometimes disproportionate to the threat real.
Major pest species – L. bostrychophila psocids is the main pests found in domestic installations, which represent over
90%, and is associated generally to consumer complaints. It is usually not found in commercial food handling
situations. Psocids different species tend to be associated with particular situations.
Environmental factors – psocids are vulnerable to drying temperature data in specific humidity and moisture, along with data on the intrinsic growth rate were considered, L.
bostrychophila ranked among other major stored food pest in terms of adaptability and potential pests. Egg laying
L. bostrychophila ceases at temperatures thrives on a diet of yeast that is normally considered a diet. It is generally accepted that psocids
are more successful on a diet in which microorganisms are present in moderation. The fact that L. bostrychophila
means that under parthenogenetic adequate environmental and dietary conditions, populations can develop rapidly and
certainly much faster than the restricted sexual reproduction.
effective methods for controlling psocids – Monitoring infestations are essential for the prevention and control strategies of
applied successfully. Can be controlled by a visual inspection, trapping, soil tests and palette "knock-
out "of the test.
Control – are psocids difficult to control because they are small and can hide in cracks and crevices to avoid pesticides
treatments. Can survive long periods of time without food and are everywhere. An integrated approach is desirable control
using all appropriate techniques consistently.
The aim should be to manipulate environmentally detrimental insects than to deny them access to
a requirement. Little can be done to test buildings and deny safe haven is difficult, although this
may be an option in small kitchens. They do not like the cold, dry and can not survive the application of dry heat humidity with temperatures of 50-60oC psocids control. As already mentioned, the freeze will kill them. Clearly, any reduction in humidity can prevent molds are an important source food.
The control can be effected by the use of fumigants, space and surface spray treatments and a wide range of pesticides
has proved effective control psocids. Products based on synthetic pyrethroids permethrin
deltamethrin and the carbamate bendiocarb are well established in the control PSoC. However, there is evidence that
certain strains of L. bostrychophila mixed function oxidase enzyme systems, which can detoxify and reduce
effectiveness some pyrethroid insecticides. This can be overcome by the use of the synergist piperonyl butoxide. PCO
therefore should be alert to the possible variability in the control accomplished with synthetic pyrethroids.
Conclusions
Psocids are pests everywhere that have the potential to cause considerable discomfort damage stored products and
pose a health hazard, especially in sensitive individuals.
The evidence shows that the complaints of the food industry have increased over the past 35 years, although the reasons are still
clear. Psocids it is likely that significant problems remain in the home and the food industry, but much
has been achieved in recent years to develop a better understanding of the pest that should contribute to improving
control in the future.
The pests and allergy problems
Other pests that cause allergy problems
Fleas
Heska in Orlando, Florida, announced in 1997 a breakthrough in dermatitis flea allergy (ADF) test. Heska
immunologists team has been carefully studying the biology of fleas – the result is the development of newly diagnosed
reagents and detection technology.
Flea allergy dermatitis HESKATM test is the first test specifically developed for IgE antibodies to flea
salivary antigens and antigens of the whole body of fleas.
flea allergy dermatitis is a common skin disease, and has traditionally been defined as an allergic reaction to fleas
bites caused by the injection of flea saliva feeds. insects associated dermatitis is a hypersensitivity to flea the whole body
antigens. The cross-reactivity has been shown that the flea allergens whole body and black fly, black ant and roach
antigens. Redness, swelling and itching are caused by different protein components in saliva The flea which can be
stimulate an allergic response. Clinical signs associated with FAD depends on the degree of sensitivity and immunological
level flea exposure.
Wasps and Bees
Some people are very allergic to things such as insect bites. When exposed to these elements may have serious
allergic response, also known as anaphylaxis.
In North America and Europe, about 100 people a year die from insect bites. Death usually comes within the first hour
after a sting and is attributed to insect allergy, not the toxic effect of the poison. It is believed that heat stroke or heart
attack can be given as the cause of death when it was actually the result of a sting. More children are stung, but in the elderly
problems people with complications health such as heart disease or chronic bronchitis, death occurs more
frequently. Most of the victims of the deadly insect bites specific IgE antibody tests.
The severity of the reaction depends, among other things, the amount of venom injected and the degree of
awareness. Some bite victims have been reported as suffering 2000 bites and survive while others receive one
deadly bite.
In general, the venom allergens honey bee allergens differ from wasps. Several suspected allergens more potent
found only in Vespula and Dolichovespula (so-called euro-or super-wasp). Clinical manifestations include large
local reactions that can spread to the limbs, disfigurement and swelling.
Very aggressive bees Honey from Africa were released by mistake in Brazil during the 1950's. These bees colonized
nests of native bees. Africanized honey bees are a major threat in the South and Central America and
predicted to be the colonization of the southern United States. In one study, compared the poisons and biochemically
immunochemically. These investigations concluded that the increased morbidity after the sting of Africanized bees was due
their behavior more offensive.
Honeybees are the only stinging Hymenoptera fluke that almost always leaves its stinger in the skin of the victim. The
poison continues pumping to the victim until the venom sac is exhausted or remove the stinger.
Wasp stings are often more a matter of concern. Among the species Vespula, Vespula vulgaris (Common wasp) is
responsible for inflicting the highest percentage of bites and has an unpleasant character. They live in large colonies, with 500 –
5,000. When a colony is disturbed, the wasps flying sentry, find the intruder and begin to itch. Venom
contains an alarm substance that tells Wasps others the location of the first bite. Then follow itching around
that site.
Whether stung by a bee or wasp at a time when susceptible people anxiety may have a lump in my throat, shortness of breath,
and low blood pressure. These severe symptoms require immediate medical attention, as it can stop breathing and death may
occur. If you see someone who has these problems, seek help by calling the emergency services. Watch and help
breathing victim if necessary.
If people have ever had a reaction, which can be repeated if exposed again. It is prudent for them to use an ID
bracelet to alert physicians. The use of antihistamine tablets will help in the short term, but treatment should be
searched.
Birds
Allergic reaction to birds is also possible. Pigeon lung (PFL) is a form of extrinsic allergic alveolitis (EAA) – a
allergic reaction in the lungs to other external allergen. The PFL is believed that small particles of dust containing pigeons
proteins cause allergic reaction.
Professor Chris Feare Wild Wings Bird Management in the United Kingdom, said, "The allergens may originate both doves"
droppings and also large amounts of dust that occurs as doves pods covered with wax their feathers, and
that concentrations of pigeons can be a source of allergens. "
There are two distinct phases, but overlapping CEA, ie, an "acute" phase, which may or may not be followed by a
"Chronicle" phase. The acute phase is the most common and as the name of the disease suggests, is primarily
interest to pigeon fanciers. However, any person who is exposed at a high level of "material of the Dove" is at risk – for pests
drivers involved in testing or removal of pigeon guano should take note.
Usually suffer from intense experience 'flu-like symptoms such as fever, chills, muscle pain, cough and / or shortness of breath, four
eight hours after exposure. The symptoms usually disappear within 48 hours but can persist for a week or more. Although
this attack is likely to go without treatment, it is important to see your doctor about your symptoms, while still present,
preferably in the starting day, as if they delay there may be no visible symptoms to the doctor to investigate.
It is important that the condition is identified as soon as possible to prevent progression to stage serious chronic
PFL. If detected and appropriate measures are taken in time, acute PFL is reversible. If undetected (or ignored)
the acute phase can be followed the chronic phase is characterized by a type of irreversible lung damage
doctors call pulmonary fibrosis. This is very serious and in extreme cases can be fatal. The main symptoms are
dyspnea, cough and weight loss, which can be considerable.
One can see that many of the symptoms are general a number of "serious" conditions, so it is important for victims
recognize that there may be a possible link with pigeons and mention to the doctor.
Chris Feare emphasizes a further complication – like "flu-like symptoms can be caused by a pathogen common
by the pigeons (and birds) and is also present in their droppings. This is Chlamydia psittaci, the cause of ornithosis
in man, it is important that the diagnosis of "flu" is correct. Like a number of other conditions last
from birds to humans in most cases the symptoms can be passed as "the flu" and is rapid and complete recovery. However,
if you happen to be one of the unfortunate few who are susceptible things could get very sick. It is not just pest
Drivers who are at risk. Even those whose homes, apartments and shops have a population Resident birds are in danger.
All the encounters with high levels of "material of pigeons" should be considered as potentially very dangerous and precautions
should be taken to minimize dust production and personal protective equipment should be used in all
times when handling these materials.
Stored product pests
Many stored product insects can cause allergies. Even the humble grain weevil (Sitophilus granarius) can produce
Allergic reactions, although the importance of allergy to corn borer in grain dust asthma has not been fully evaluated.
farmers grains can be sensitized and develop asthma due to one or more of the allergens in their organic
the environment. In literature, at least three cases of asthma in the laboratory workers were described by the grain weevil.
This brings us to the issue of ingestants allergens, ie, eating or accidentally swallowing insects allergenic material.
As a nation we are not accustomed to eating in "mistakes," direct evidence for allergies to insect food is practically
nonexistent.
However, the entomologists are sometimes treated to accounts Nebula people sick after eating deliberately
insects. Since almost everyone can appoint at least one food that turns your stomach, it is unclear what role, if any,
psychological factors may have played in these conditions. We can, however, get a sense of control
human experiments done with the preparations of the common insects infesting food.
A classic study of Brown in 1967 Bernton and extracts used dialysate in seven of these insects in testing skin sensitivity
of subjects with and without known allergies. Test extracts including the rice weevil (Sitophilus oryzae), fruit fly
(Drosophila melanogaster), the Indian meal moth (Plodia interpunctella), toothed grain beetle (Oryzaephilus
surinamensis), rust red flour beetle larvae and adults (Tribolium castaneum), confused flour beetle (Tribolium confusum)
and lesser grain borer (Rhyzopertha dominica).
Of the 230 allergic patients, 68 (29.6%) reacted positively to one or more of the dialysate insect extracts. Amazingly,
the 194 non-allergic subjects, 50 (25.8%) were sensitive to at least one extract. A total of 333 positive reactions
observed. The degree overall sensitivity was practically the same for both groups, with the Indian meal moth extract
resulting in more positive reactions followed by extracts flour beetle larvae of red rust, red rust flour beetle adults, rice
weevils, fruit flies, confused flour beetles, tooth Saw grain beetles, and less grain borers.
The question arises where more than 25% of the general population might have acquired sensitivity these
insects. At one time or another, most people have had to clean out their closets, as a result of an infestation by one or
greater accumulation of food pests. If the problem is bad enough (and recurrent), the sensitivity could be related to inhalant or contactant
origin of insect allergens.
More probable, however, these allergies are the result of ingestion of small amounts of insect material in food for a lifetime.
Despite dominating the production and storage methods, small amounts of insect material will find its way into
our food. The Indian meal moth and their families for example, may represent a persistent threat and where sweets are notorious
manufactured or stored. Stored-product moths also attack flour, pasta and nuts. beetles and grain weevils
a constant threat to stored grains, and has not opened a box of cake mix or cornmeal, only discover flour
beetles that infest the content?
We are not ready to eat foods that displaying obvious signs of insect contamination, but we're than likely get
occasionally small amounts of insect material in food that we consider healthy. For most people this level of exposure is
medically insignificant. For people with known allergies, especially those of the varieties of food and insects, the matter
becomes a problem. In insects for food, is the strict avoidance of exercise of this novel sensitized
kitchen or take your chances?
For most people, working with or accidentally eating insects that pose little if any health risk, especially if they have
history of allergy to insects and other arthropods. However, since the sensitivity can be acquired through repeated exposure to
an allergen, a measure of oversight is in order. Anyone familiar with insects, arthropods or birds would be desirable allergies
exercise caution.
