Predicting insecticide resistance: mutagenesis, selection and response. (1/238)

Strategies to manage resistance to a particular insecticide have usually been devised after resistance has evolved. If it were possible to predict likely resistance mechanisms to novel insecticides before they evolved in the field, it might be feasible to have programmes that manage susceptibility. With this approach in mind, single-gene variants of the Australian sheep blowfly, Lucilia cuprina, resistant to dieldrin, diazinon and malathion, were selected in the laboratory after mutagenesis of susceptible strains. The genetic and molecular bases of resistance in these variants were identical to those that had previously evolved in natural populations. Given this predictive capacity for known resistances, the approach was extended to anticipate possible mechanisms of resistance to cyromazine, an insecticide to which L. cuprina populations remain susceptible after almost 20 years of exposure. Analysis of the laboratory-generated resistant variants provides an explanation for this observation. The variants show low levels of resistance and a selective advantage over susceptibles for only a limited concentration range. These results are discussed in the context of the choice of insecticides for control purposes and of delivery strategies to minimize the evolution of resistance.  (+info)

Rainbow trout leucocyte activity: influence on the ectoparasitic monogenean Gyrodactylus derjavini. (2/238)

The ectoparasitic monogenean Gyrodactylus derjavini from rainbow trout Oncorhynchus mykiss was exposed in vitro to macrophages isolated as peritoneal exudate cells or as pronephros cells from the host. Cells colonized the parasite especially in the mannose-rich regions in the cephalic ducts where ciliated structures were abundant. Opsonization with fresh serum, in contrast to heat-inactivated serum, enhanced colonization also on other body parts. The adverse effect of the activated macrophages towards G. derjavini was associated with a heat-labile component released from these cells to the culture medium. Analysis of substances released from the cells showed reactivity for a number of enzymes, complement factor C3, interleukin (Il-1) and reactive oxygen metabolites. Chemotaxis assays with pronephric leucocytes showed chemoattractants in G. derjavini, and the respiratory burst level of macrophages was slightly elevated due to parasite exposure. It is suggested that skin leucocytes contribute to an increased level of complement factors in the trout skin during the host response, whereby a hostile microenvironment for the parasites is created. In addition, the IL-1 production could affect mucous cell secretion and hyperplasia and add to the antiparasitic action of the epithelium. Likewise, reactive oxygen metabolites and various enzymes are likely to be involved in the skin response.  (+info)

Changes in physiological parameters and feeding behaviour of Atlantic salmon Salmo salar infected with sea lice Lepeophtheirus salmonis. (3/238)

Atlantic salmon Salmo salar L. artificially infected with salmon lice Lepeophtheirus salmonis (Kroyer 1837) recovered from detrimental physiological changes and skin damage induced by preadult lice as the parasites matured. Growth rates of Atlantic salmon remained unaffected by lice infection, but food consumption decreased with increasing feeding and movement of the lice prior to and post-mating, correlating with the appearance of head erosions and detrimental changes in physiological integrity. Food consumption of the fish increased as the lice moulted to the adult stage and gravid female lice settled in a posterior location on the fish, subsequently reducing the impact of infection and allowing recovery of the skin damage. However, the impact of preadults was limited, as the decrease in food consumption of fish at 21 d post-infection had no effect on either the specific growth rate or condition factor of the fish. Furthermore, the intensity of lice infections at each of the sample days was not correlated with food consumption, specific growth rate or any of the haematological or physiological parameters measured, either before or after infection, indicating that lice intensity was independent of social dominance/subordinance. This work has provided the first evidence that infected fish can recover from the detrimental changes caused by lice infection, even when they are still infected with lice. If fish can survive the preadult stage of lice, then the mortal impact of lice infections is greatly reduced.  (+info)

Extent of gill pathology in the toadfish Tetractenos hamiltoni caused by Naobranchia variabilis (Copepoda: Naobranchiidae). (4/238)

Sanguinivorous Naobranchia variabilis prefer the first gill arch, external hemibranch and anterior end of the gill arch. The smallest N. variabilis observed attached to fish by a thin filament which connects fused tips of second maxillae to a 'plug' inserted into the gill tissue. Second maxillae enlarge to encircle and increasingly compress the gill filament, which results in a thin layer of epithelium and connective tissue overlying the cartilaginous supporting bar. Early juveniles cause little tissue proliferation, but the extent of proliferated epithelial and connective tissue (PR) adjacent to the maxillae increases from late juveniles to subadult and adult copepods. Most variation in length of gill filament damage (PL, proliferated and compressed tissue) among age classes is explained by maxilla length (ML, length of compressed gill filament); adult trunk width (TRW) explains an extra, small amount of variation, but not trunk length (TRL) or total fish length (TL). Most variation in ML is explained by TRW of adults, subadults and late juveniles, and TRL of early juveniles. PR is explained by TRW for adults, but by ML for other ages. These patterns are due to elongation of the juvenile trunk during growth and lateral expansion of adult egg pouches during maturation. Up to 38 N. variabilis, average (avg.) = 9.3, infected individual Tetractenos hamiltoni and damaged up to 3.4% (avg. 0.72%) of total filament length and 8.6% (avg. 2.1%) of gill filaments per fish.  (+info)

Chemical control of Haematobia irritans with 0.5% topical ivermectin solution in cattle. (5/238)

A field trial was conducted to evaluate the efficacy of a topical formulation of ivermectin administered at the dose of 500 micrograms/kg against horn flies (Haematobia irritans) in cattle. Eighty-eight cattle in four herds naturally exposed to horn flies were used in the trial. Replicates were formed of two herds. Within replicates, one herd was randomly allocated to the untreated control and the other to the ivermectin treatment group. Horn fly counts were taken on the treatment day (Day 0) and on Days 7, 14, 21, 28, and 35 post-treatment. There were no horn flies on any cattle in the treatment group, whereas all the control cattle were continuously infested by horn flies on each examination day.  (+info)

Carotenoids, sexual signals and immune function in barn swallows from Chernobyl. (6/238)

Carotenoids have been hypothesized to facilitate immune function and act as free-radical scavengers, thereby minimizing the frequency of mutations. Populations of animals exposed to higher levels of free radicals are thus expected to demonstrate reduced sexual coloration if use of carotenoids for free-radical scavenging is traded against use for sexual signals. The intensity of carotenoid-based sexual coloration was compared among three populations of barn swallows Hirundo rustica differing in exposure to radioactive contamination. Lymphocyte and immunoglobulin concentrations were depressed, whereas the heterophil:lymphocyte ratio, an index of stress, was enhanced in Chernobyl swallows compared to controls. Spleen size was reduced in Chernobyl compared to that of two control populations. Sexual coloration varied significantly among populations, with the size of a secondary sexual character (the length of the outermost tail feathers) being positively related to coloration in the two control populations, but not in the Chernobyl population. Thus the positive covariation between coloration and sexual signalling disappeared in the population subject to intense radioactive contamination. These findings suggest that the reliable signalling function of secondary sexual characters breaks down under extreme environmental conditions, no longer providing reliable information about the health status of males.  (+info)

Treatment of Microcotyle sebastis (Monogenea: Polyopisthocotylea) infestation with praziquantel in an experimental cage simulating commercial rockfish Sebastes schlegeli culture conditions. (7/238)

The antiparasitic efficacy of praziquantel against the blood-sucking polyopisthocotylean Microcotyle sebastis was tested in an experimental cage simulating commercial rockfish-culture conditions. Juvenile rockfish Sebastes schlegeli were separated into 4 pilot net-pens, and the fish in the groups were either fed a control diet (Group C), fed a praziquantel-adsorbed diet (Group F), bathed in 100 ppm praziquantel for 4 min (Group B), or bathed in 100 ppm praziquantel for 4 min and then fed a praziquantel-adsorbed diet (Group BF). The results of the present study indicate that feeding a praziquantel-adsorbed diet significantly reduces the abundance of M. sebastis infestation, and bathing in 100 ppm praziquantel for 4 min is effective for controlling M. sebastis infestation in practical rockfish culture systems.  (+info)

Bovine teat atresia associated with horn fly (Haematobia irritans irritans (L.))-induced dermatitis. (8/238)

Mammary gland lesions characterized primarily as mammary teat atresia were observed in a Limousin beef cattle herd in eastern Texas. Atresia of multiple teats per mammary gland was reported in first-calf heifers at the time of calving. Pathogens were not identified in eight mammary glands collected at slaughter. Histology of affected glands demonstrated superficial and deep perivascular inflammation and fibrosing dermatitis of teat and mammary gland skin that resulted in formation of the atretic lesions of glandular tissue. Institution of a horn fly (Haematobia irritans irritans (L.)) control program using insecticide-impregnated ear tags was associated with elimination of the problem from the herd.  (+info)

The surface temperature (within 1 m) at the fixed hydrographic station in Sognesjøen (outer region of Sognefjorden) during January and February was 6.4 and 3.5°C in 2013 and 6.1 and 5.7°C in 2014 (6.3 and 5.5°C on average for the period 2000− 2012, www.imr.no), respectively.. Consequently, the temperature was well below temperatures that routinely occur during the summer and early autumn months in Sognefjorden (July average = 15.4°C).. According to the model by Stien et al. (2005), it will take more than 28 d for individuals to reach the chalimus 1 stage at 5.7°C. This suggests that the production of the main proportion of the lice observed on the fish occurred in January or February. Natural salmon lice intensity during winter months on sea trout is usually not above 3 lice per fish, with a prevalence seldom exceeding 20% (Schram et al. 1998, Rikardsen 2004).. Consequently, the prevalence and abundance observed here are above normal and can be defined as a winter epizootic.. One likely ...

In March 2018, the Scottish Parliaments Environment, Climate Change and Land Reform Committee published a report on the environmental impacts of salmon farming. The report voiced deep concerns about the continuing growth of the sector absent a full understanding of its environmental impacts. The committee was particularly concerned about the 25% mortality rate of farmed salmon, sea lice epidemics and the impact on wild stocks, and the use of chemicals on the environment. Discharge of waste nutrients and their interaction in the wider marine environment, including solid wastes from open net pen farms and effects on sediments, was also a major concern. The committee concluded that not enough is known about the environmental effect of salmon farming and that the status quo is not sustainable.. In 2015, Scottish fisheries scientists, joined by peers from Norway and Ireland, reviewed over 300 scientific publications on the damaging effects of sea lice on sea trout stocks in salmon farming areas and ...
The examples that follow illustrate the often forgotten impact of multicellular endoparasites on human health and the variation in their life cycles and transmission routes. However, before we go on, it is worth observing that there exists an additional category of multicellular parasites: ectoparasites. Ectoparasites are invertebrates (animals without backbones) that live on the surface (ektos is Greek for outside) of the human body, such as head lice, body lice and ticks. Their bites can cause intense irritation and they also transmit some potentially life-threatening pathogens to humans, such as the bacteria that cause typhus [tye-fuss]. People with typhus develop a very high fever (body temperature well above the normal 37 °C), severe headaches, muscle pain and a dark rash. It can spread rapidly in overcrowded communities, where lice and ticks proliferate because people cannot easily wash themselves or their clothes (Figure 4).. ...

Outcomes of infections with the salmon louse Lepeophtheirus salmonis vary considerably among its natural hosts (Salmo, Oncorhynchus spp.). Host-parasite interactions range from weak to strong host responses accompanied by high to low parasite abundances, respectively. Parasite behavioral studies indicate that the louse prefers the host Atlantic Salmon (Salmo salar), which is characterized by a weak immune response, and that this results in enhanced parasite reproduction and growth rates. Furthermore, parasite-derived immunosuppressive molecules (e.g., proteases) have been detected at higher amounts in response to the mucus of Atlantic Salmon relative to Coho Salmon (Oncorhynchus kisutch). However, the host-specific responses of the salmon louse have not been well characterized in either of the genetically distinct sub-species that occur in the Atlantic and Pacific Oceans. We assessed and compared the transcriptomic feeding response of the Pacific salmon louse (L. salmonis oncorhynchi,) while
The efficacy of a range of anti-parasitic chemotherapeutic agents against the salmon louse Lepeophtheirus salmonis following topical application was studied in vitro and in vivo. In general, adult and preadult lice were susceptible to a wide range of compounds with dose rates, following 1 hour exposures, ranging several orders of magnitude (10.0 - 0.001 mg/L). Overall the pyrethroid compounds which were tested were found to have the widest therapeutic ratios, indicating the potential of this group of chemotherapeutants for sea lice control. Resistance to the organophosphorus (OP) compounds dichlorvos and azamethiphos was detected in isolated populations of lice. Field trials with azamethiphos indicated that the compound was highly efficacious against sensitive lice (@ 0.1 mg/L; however, where resistance was present, efficacy (@ 0.2 mg/L) was highly variable. When used at the above dose rates, azamethiphos was found to be well tolerated by fish as indicated by a lack of significant brain ...
The salmon louse (Lepeophtheirus salmonis) is an ectoparasitic copepod feeding on skin, mucous and blood from salmonid hosts. Recently it was shown that L. salmonis infections in farmed fish induce epizootics in wild fish [1,2]. The life cycle of L.salmonis consists of 8 developmental stages separated by ecdysis [3,4] and after the final molt, females develop into mature adults that continuously produce eggs for life. The first free-living larvae (naupli I) hatch directly from egg-strings attached to adult females and all three larval stages (naupli I, naupli II and the infectious copepidid stage) can be transported by the ocean currents over large distances depending on hydrographical conditions [5]. After host settlement the infectious copepodids stage molt into chalimus. The two chalimus stages, all separated by molting, are anchored to the host by a frontal filament [6], which restricts the feeding area. However, in the succeeding pre-ad I and -II and adult stages the salmon louse can move ...

The effects of Lepeophtheirus salmonis infections on the stress response and immunological status of Atlantic salmon (Salmo salar)
Salmonid aquaculture is an important industry on both sides of the North Atlantic, contributing to the local societies and producing highly demanded marine food. However, the industry has its environmental challenges, such as the ectoparasitic salmon louse (Lepeophtheirus salmonis). The salmon louse occurs naturally in the North Atlantic wherever there are wild salmonids. With the onset of salmonid farming in open net pens, the parasite obtained access to hosts held at high densities throughout the year. Fish farmers around the North Atlantic have since the 1970s used chemicals to control the number of lice in the fish pens. However, the salmon louse has developed resistance to four out of five chemical groups that have been available, forcing the industry to look for alternative non-chemical methods.. A fascinating aspect with the salmon louse is that there appears to be only one, pan-Atlantic, population. Because of the migratory life history of one of the main hosts, the wild Atlantic salmon, ...
The horn fly, Haematobia irritans (Linnaeus, 1758) (Diptera: Muscidae) is one of the most important ectoparasites of pastured cattle [1]. This fly was originally introduced from Europe and currently represents a tremendous health problem for cattle in the Americas from Southern Canada to Argentina [2]. Although horn flies parasitize mainly cattle, occasionally they feed on horses, sheep and dogs [3].. The developmental cycle of H. irritans is very short, taking from 10 to 14 days to complete. Larvae and pupae develop on dung and once the flies emerge from pupae, immediately start and remain feeding on cattle during their whole life. Flies leave the host only to move to others or to lay eggs on fresh manure [1]. Both males and females feed 24 to 38 times per day ingesting an average of 14.3 mg blood per fly [4].. Horn flies infestations interfere with animal feeding, thus producing significant reductions in weight gain and milk production [5, 6]. The economic impact of H. irritans on livestock in ...

Species composition, seasonal dynamics, and a load of ectoparasites per individual and population of the pygmy shrew Sorex minutus have been examined in coniferous and mixed forests of the Novgorod Province during the period 1999-2003. Trapping of mammals was carried monthly, with exception of few accidental gaps. The Gero traps were used for catching micromammalian hosts. The lines of trap were checked 2 times a day, places of lines changed each 3-5 day. Total number of micromammalians collected during the period of study is 3215, including 265 specimens of the pygmy shrew S. minutus. Parasite fauna on the pygmy shrew included 13 ectoparasite species: fleas - 8, ixodid ticks - 2, gamasid mites - 1, and myobiid mites - 2 species. Species composition, occurrence and abundance indices of parasites changed during the year. In total, about 55% shrew specimens are infected with ectoparasites. The infracommunity of ectoparasites on the pygmy shrew usually consists of 1-4 species. Mean number of all ...
These devices retail for $20 to $40. I would take that money and use it to launder all clothes and put them in a sealed tote, because this would protect them more than [ultrasonic] detection, Jones says.. Drying bedding and clothing at high temperatures for 20 minutes kills bedbugs, she says.. What else can you do?. Bedbugs are a labor-intensive and time-intensive insect to deal with, Jones says. If you suspect you have bedbugs, call a professional and they can tell you if it is a look-alike or a real bedbug.. Dini Miller, PhD, is an associate professor of urban entomology at Virginia Tech in Blacksburg, Va. If these worked, we wouldnt have a bedbug problem in the U.S., she says.. Unfortunately, we dont have a great answer for bedbugs right now, she says. We are pretty good at taking care of 12 bedbugs, but where things get tough is when you have 1,200.. Heat and insecticides are the best available answers now, but they are not fail-safe.. The best way not to get a bedbug infestation ...
Cover: It works! Juvenile lumpfish, Cyclopterus lumpus, is the new and effective biological delouser for farmed Atlantic salmon. The salmon louse, Lepeophtheirus salmonis, is an ectoparasitic copepod that causes major economic losses in Atlantic salmon aquaculture and a practical and feasible solution to this problem is of paramount interest. Imsland et al. (bio036301) assessed the efficacy of lumpfish grazing on attached sea lice on Atlantic salmon and there were clear signs of lumpfish grazing on sea lice, with significantly lower average levels of sea lice per salmon. Overall, the data indicate that lumpfish is a suitable cold-water option for biological delousing of Atlantic salmon under large-scale production conditions.

Most of the 90 or so species of bedbug feed on birds or bats. Only two are pests on humans: Cimex lectularius, and C. hemipterous. Although archaeological records show these parasites have been living with humans for thousands of years, their bites do not pass on any known diseases. A bedbugs saliva contains anti- clotting proteins along with other glycoproteins and lipoproteins. A bite can cause immune responses to these proteins ranging from small red swellings to large blisters. Intense multiple feedings can result in bruising and even anemia in small children.. Bedbugs are wingless and so must stay within range of their hosts. An unfed bedbugs flattened body lets it hide in narrow cracks, behind baseboards or in the crannies and seams of bed frames and mattresses. Generally nocturnal feeders, bedbugs are sensitive to low humidity, cold and high heat. Like most other blood feeders, bedbugs are usually first attracted to carbon dioxide in the hosts breath and then by body heat. Nymphs and ...

If you are waking up with small, red, itchy bumps on your skin, then it is most likely you have been infested with bedbugs! This is a very unpleasant reality for most people. Some of us usually have a common misunderstanding that bedbugs are due to poor housekeeping. But in reality, they are brought into your home on luggage or clothing particularly if you make contact with a person who has bedbugs or if you stay in a hotel that has been infested with these creatures. Common household bedbugs are found almost everywhere in the world. These creatures are known to adjust very well to the human environment especially in temperate climates. There are a number of other pests that resemble bedbugs both in appearance and habits. For you to make proper identification, you might need to magnify it or sometimes if you have experience with different species.. There are various types of bedbugs and their related pests. These insects live by sucking blood from their hosts such as birds, bats, some rodents, ...

Raleigh, N.C. For anyone hoping theres a quick, easy treatment for bedbugs in the near future, take note of the hesitation in Coby Schals response.. Schal is a North Carolina State University urban entomologist - the academic title for a guy who studies cockroaches and, of late, bedbugs - and he gets asked all the time whether a miracle might soon hit the market to stem growing infestations of the blood-sucking pests.. Pause.. Long, scary pause.. I wish I had a short-term answer to that, he says. Another pause. But I dont.. Oh, agony and woe.. And the pessimism among leading bug scientists is nothing compared to the downer from exterminators, who now rank bedbugs among their worst and most prevalent problems.. Donnie Shelton, owner of Triangle Pest Control in Raleigh, said his bedbug business has increased 400-fold - just this year.. He bought a dog, named Scout, who is specially trained to sniff out bedbug infestations. Next month Shelton will offer a heat-based eradication system, which ...
In this preliminary study, two heifers were exposed to horn flies fed blood that contained Staph. aureus to determine if mastitis could be induced by fly bites. Results indicate that the horn fly (Haematobia irritans) can be colonized with Staph. aureus during feeding and can remain colonized for up to four days, with substantial numbers of organisms present. When colonized horn flies were allowed to feed on teats of uninfected dairy heifers, mastitis with the same Staph. aureus strain resulted. This indicates that the horn fly can transmit Staph. aureus to heifers teats if a source of organisms is present. That source was shown to be present in the existing scabs on the teat ends of heifers. High concentrations of Staph. aureus were found in scab material present on heifers teats. When uncolonized flies were allowed to feed on this material, they became colonized with Staph. aureus just as readily as flies that had fed on experimentally infected blood. Thus, a vector capable of transmitting ...

Ectoparasite biodiversity across a range of Western Australian threatened mammals is being described as part of a larger project examining the presence and impact of parasites in fauna. Fleas, ticks, mites and lice are collected in animals that are trapped across the State as part of the Department of Environment and Conservations threatened mammal monitoring programs, an Australian Research Council funded project and the Woylie Conservation Research Programme.. Most of the published work on ectoparasite biodiversity was done in the first half of the last century and is based on drawings of morphological features. These monographs have been found to be inadequate and many rare mammals have no records of their parasite fauna described. New methods utilising PCR and scanning electron microscopes are being used to help describe species of ectoparasite. A tick found on the woylie may prove to be a new species. PCR is also being used to examine the role of ectoparasites as vectors of disease. The ...
Identify all the spots in the house where bedbugs are present. Be extremely thorough and look in any cracks and crevices. Use the flashlight to get a better look in dark corners.. Remove any clutter from the infected areas. Bedbugs and many other insects like to shelter in clutter. Take this material outside or treat it by applying baking soda. Do not move the clutter to another area of the house, as this will only spread the bedbugs.. Put the baking soda in a bowl. Dip the paintbrush into the bowl.. Use the paintbrush to spread a light layer of baking soda around any cracks and crevices where you suspect bedbugs are hiding.. Use the paintbrush to spread baking soda between the mattress and the bed spring. Also cover all surfaces of the mattress as well as the frame.. Apply baking soda anywhere else you suspect bedbugs to be. Infestations are typically centered around the sleeping area but can spread from there to other rooms.. Vacuum the baking soda after several days and then reapply the ...
For many of us, the bedtime warning, Dont let the bedbugs bite! was just a silly thing grown-ups said. Now its a real and rising threat in many parts of the country.. After more than 50 years of virtual elimination in the U.S., bedbugs have made a roaring comeback over the last decade, spreading most rapidly in the last six years, according to Richard Cooper, a research entomologist and vice president of BedBugCentral.com. The nocturnal feasters come out of the woodwork (literally), the mattress and the bedding to sink their teeth into sleeping humans and suck their blood. And they hitchhike on people from one location to another.. Bedbugs dont discriminate, says Cooper. Theyre not a sign of poor hygiene, but people still say, I wouldnt get bed bugs. That attitude has fostered the spread.. Once bedbugs settle into an environment, theyre very tough to stop. Bedbugs typically first install in sleeping areas, but they eventually move into closets, dressers, even behind picture frames. ...

The Gries began their research eight years ago when Gerhard, who is internationally renowned for his pioneering work in chemical and bioacoustic communication between insects, began searching for pheromones that could lure and trap bedbugs.. Regine worked with him, running all of the lab and field experiments and, just as importantly, enduring 180,000 bedbug bites in order to feed the large bedbug colony required for their research. She became the unintentional host because, unlike Gerhard, she is immune to the bites, suffering only a slight rash instead of the ferocious itching and swelling most people suffer.. The Gries and their students initially found a pheromone blend that attracted bedbugs in lab experiments, but not in bedbug-infested apartments. We realized that a highly unusual component must be missing-one that we couldnt find using our regular gas chromatographic and mass spectrometric tools, says Gerhard.. Thats when they teamed up with Britton, an expert in isolating and ...

Ovulation, fertilization, and early embryonic development in the menstruating fruit bat, Carollia perspicillata[2] Graafian follicles developed large antra and exhibited preovulatory expansion of the cumulus oophorus. Ovulation had occurred in some on the morning, and in most by the evening, of day 1. The single ovum was released as a secondary oocyte and fertilized in the oviductal ampulla. Ovulated secondary oocytes were loosely associated with their cumulus cells, which were lost around the initiation of fertilization. Supernumerary spermatozoa were occasionally noted attached to the zonae pellucidae of oviductal ova, but never within the perivitelline space. By day 2, most ova had reached the pronuclear stage and by day 3, early cleavage stages. Several lines of evidence indicate that C. perspicillata is a spontaneous ovulator with a functional luteal phase ...

The common bedbug (Cimex lectularius) is increasingly prevalent and a source of concern and questions for patients. In addition to a range of cutaneous presentations and potential for serious sequelae, bedbug bites cause significant psychological distress and create an economic burden associated with infestation control..
Bedbugs are parasites that rely on blood to survive. They can feed on the blood of any mammal, although they appear to prefer the blood of humans. They are attracted to the warmth surrounding mammalian bodies and the carbon dioxide present in breath expiration. It is usually these factors that guide bedbugs to locate a suitable host for feeding.. Bedbugs usually bite the shoulders and arms of humans. The proboscis of the bedbug pierces the skin and allows the bedbug to feed on the blood. The saliva of the bedbug is injected into the host, which contains an anticoagulant substance that some people have an allergic reaction to.. The feed process takes approximately 5-10 minutes. The bedbug becomes filled with blood, changing in color from light brown to rusty red.. ...
As of late, there are several stories in the news, about bed bugs carrying diseases, and transmitting them to their victims. This isnt hard to imagine, because other blood-feeding parasites, such as mosquitoes, are disease vectors, transmitting malaria, yellow fever, and even the deadly West Nile virus.. Well, thankfully with bed bugs, this is not the case. It seems one of the threats they do pose to humans, however, is the actual infestations themselves, which technically are a disease. A disease can include any parasitic relationship, where an ectoparasite (bed bugs) feeds on a host (humans).. One of the symptoms of bed bugs disease (read:infestations) include the red, itchy bite marks, often left behind after a nighttime feeding frenzy. The bites, interestingly enough, closely resemble mosquito bites, and are about as itchy. However, only about half of all people bitten by bed bugs suffer reactions to the bites.. The itching and swelling attributed to the bites is actually your bodys ...

Now that its time to nip your pest problem in the bud, youll be delighted to know that you can use at-home methods, benign methods or chemical methods. Depending on the scope of the infestation, a combination of treatments will be more effective than one by itself. Heat is excellent when it comes to killing off bedbugs. Their little bodies cant withstand temperatures above 115 degrees. They also die in temperatures below 32 degrees. Thats why you can soak the items in extremely hot or cold water. Alternatively, you can leave the items in the car on a sweltering or frigid day. Applying constant steam to infested areas is another great way to get the job done. However, to achieve faster results, you should use EPA-registered insecticide thats specifically designed for bedbugs. Keep in mind that foggers or bug bombs can pose a threat to your familys health if you dont exercise caution or follow the instructions. ...
A defining characteristic of family Phyllostomidae is the presence of a noseleaf. This structure is used to send out and interpret incoming high frequency sounds. Some species have developed incredibly large nose-leaves, while they may be completely absent in other species. When present, noseleaves arise from a fleshy plate that surrounds the nasal apertures and stands erect behind these openings. Noseleaves may be long or short, slender or broad. In vampire bats (Desmodontinae) the noseleaf is greatly reduced and modified into a complex series of folds and bumps around the ornamented narial plate, whereas members of subfamily Phyllostominae have highly developed noseleaves. Phyllostomids range dramatically in size; the smallest members, little white-shouldered bats have a forearm length of 26 mm, while the largest members, spectral bats, have forearm lengths of up to 106 mm. Their body size is closely related to food habits and modes of flight. Bats that consume larger food items are generally ...

Prof Siva-Jothy commented that, before WW2, bedbugs were a fact of life in many countries, including the UK and that management of bedbugs, rather than their elimination, was usually the approach that was taken. Crevices in wooden furniture and beds was a particularly popular home for bedbugs. It was to combat this that the metal hospital beds were introduced; they provided few hiding places for bedbugs and could easily be treated with boiling water as a further precaution. Similarly, many hospitals and hotels built in the 1930s used metal framed windows and mimimalist features to reduce the number of possible bedbug hiding places. This all changed at the end of WW2 when DDT was introduced - it was a devastatingly effective insecticide and bedbugs were soon virtually eliminated from homes, hotels and hospitals through its use ...
