Bed bug Cimex lectularius

Dublin, Ireland (PRWEB) April 21, 2017

National pest management association survey conducted in 2010 and more recently in 2015 shows the dramatic increase in the number of bed bug infestations over the 5-year period. In 2015 10% or US$750 million per annum of the total revenue from pest management companies was from the treatment of bed bug infested properties.

The health and economic consequences of bed bug infestations are only just starting to be realised.

People can experience various forms of allergic reactions including anaphylaxis, secondary bacterial infections.

The types of properties that are being infested are also on the rise with libraries, retail outlets and Doctors facilities being affected more since the 2010 NPMA survey. Methods for detecting bed bugs have not changed between 2010 and 2015, with visual inspection still the most used technique followed by passive traps. Unfortunately, all these methods rely on the need to see the bed bugs which is a problem if you have a small population that is intent on hiding deep in cracks and crevices in your furniture.

The increase in bed bug infestations are a growing health concern. Modern non-visual detection methods must be developed to assist property owners in discovering efficiently if their homes or businesses are affected said Dr. Bruce Mitchell, CEO of airmid helathgroup

airmid healthgroup offer a large array of bed bug testing options to investigate product protective mechanisms towards bed bugs. airmid have developed assays using artificial bed bug feeders to investigate if materials are bite proof to all developmental stages during the bed bug life cycle. airmid have also worked using both small and large scale barrier assays to ensure products prevent the escape of bed bugs once entrapped in a protective barrier case. More bespoke bed bug testing includes viability and repellency assays. These assays have a standard procedure which can be adapted based on the type of product that is being tested.

All testing can be adapted to test different manufacturer products such as looking at the difference between the product as a liquid vs embedded in the material.

The life cycle of an insect describes the development of an insect from the egg stage to adult. The process is referred to as metamorphosis. Metamorphosis is the process that the insects undergo to change from egg to adult. During complete metamorphosis, the insect egg is laid and when the egg hatches, a larva emerges that has little resemblance to adults. After feeding for a period of time, the larva changes to a new appearance. This stage in development is called the pupal stage. During the pupal stage, the insect will rest for some time before completing the final stage in development. When the pupa develops into an adult and emerges, the final stage of metamorphosis is achieved.

Bed bugs evolve in a process called simple metamorphosis. This means that the juveniles have the appearance of adults and there is no resting or pupal stage. So the bed bug life cycle goes from egg to nymph, progressing through five nymphal stages, to adult, which then lays eggs and the process starts again.

Eggs take about a week to hatch. Bed bugs are most active when their living space is just under body temperature, so a room temperature that is about 80 Fahrenheit is hospitable. After hatching, the nymphal stages begin and if there is adequate food, temperature, and humidity of about 75%, bed bugs will thrive. They can produce several generations per year, so egg to egg can be timed in just a few months.

Female bed bugs can lay hundreds of eggs in her lifetime if there is an adequate population of males to ensure continuous egg production. Most eggs will hatch if conditions are right and newly hatched nymphs must feed soon after hatching.

While it is rare in normal populations, there are documented cases where bed bugs have been dormant and waiting for a host for over a year. Moreover, there have been rare cases where bed bugs have survived two years without feeding.

Bedbug Life Stages – Bedbug Life Cycle

Post date: April 6th, 2017

Bed bugs are nocturnal, reddish-brown insects that feed on the bloodof humans and other warm-blooded animals. These wingless insects have dorsoventrally flattened bodies that allow them to hide in areas such as floor cracks, carpets, beds and upholstered furniture.

Eggs

A bed bugs life begins with an egg, grain like and milky white in color. Female bed bugs lay between one and five eggs each day and may lie up to 500 eggs within one lifetime. Eggs are laid singly or in clusters and are placed withintight cracks or crevices. The egg is approximately 1 mm in length and is comparable in size to two grains of salt. Within two weeks, eggs hatch and immature bed bugs begin immediately to feed.

Nymphs

These young bed bugs, or nymphs, pass through five molts before reaching maturity. Although nymphs appear similar to adults, they are smaller in size and are not yet sexually mature.Young nymphs are also yellow-white in color, while older nymphs and adults are reddish-brown. In order to complete a molting stage, each nymph requires a blood meal. At room temperature, nymphs molt and become adults within five weeks.

Adults Upon reaching maturity, bed bug adults often make weekly feedings. The life span of a bed bug most commonly ranges from four to six months. However, some bed bugs may live up to a year under cool conditions and with no food.

One of the most hotly contested debates today involves the recent uptick in violent crime and the extent to which increases in violence may be explained by the "Ferguson effect," whereby the increased scrutiny of police since the 2014 Ferguson unrest has been hypothesized to lead police officers to become more hesitant and less aggressive. Chicago is an epicenter for much of this controversy, and on numerous occasions President Trump has threatened to "send in the feds."

In an article published today in Significance, the official magazine and website of the Royal Statistical Society (RSS) and the American Statistical Association (ASA), Arizona State University professors Sherry Towers and Michael D. White examine violence in Chicago and test whether the trends are consistent with the "Ferguson effect." They also test a competing claim proposed by Former NYPD Commissioner William Bratton that much of the recent violence in Chicago is tied to the proliferation of guns in that city.

Towers and White found no evidence of a Ferguson effect in Chicago.

"Murders and gun assaults in Chicago began increasing before Michael Brown's death in Ferguson," says Towers, a research professor in the Simon A. Levin Mathematical and Computational Modeling Sciences Center at Arizona State University in Tempe.

They did find a strong association between firearms availability and gun violence in Chicago, supporting Commissioner Bratton's argument.

"Our analysis highlights the importance of including measures of firearms proliferation when studying trends in violence in Chicago and elsewhere," says White, a policing expert and professor in the ASU School of Criminology and Criminal Justice in Phoenix.

Bed Bug Life Cycle – City of Sioux Falls

Post date: April 5th, 2017

Life Cycle/Biology of Bedbugs

The female bedbug will seek out areas that meet three requirements: water, food, and shelter. Because humans are their main food source they will often find harborage in areas close to people where they can feed without being harmed. This is usually close to a bed where people sleep, on mattresses, headboards, footboards, or end tables. The female can lay up to 5 eggs a day throughout her life, which could be as long as 612 months; that is more than 1,000 eggs per female per lifetime!

The eggs are attached to a surface with a cement-like substance, making sure that they arent easily disrupted or dislodged. The eggs are very small and translucent. They will hatch approximately one week later to the first of five nymphal stages, or instars.

The nymph is originally very small (1 mm) and light in color. They require the blood of a host in order to molt to the next stage of development, progressively growing to 4 or 5 mm in size and getting darker as they mature. In the absence of a host, bed bugs can live for months without a blood meal and remain dormant until resources are available. The nymphs will progress through the five stages over a period of about one month before becoming adults.

Adult bedbugs are approximately 7 mm in size and can live for approximately one year in optimal environments. As long as adequate resources are available, they will thrive. You can imagine the number of bedbugs that can exist in an area if left unaddressed!

Comments Off on Bed Bug Life Cycle – City of Sioux Falls

A report out of Australia demonstrates for the first time that bed bugs can induce a potentially dangerous (and possibly even deadly) systemic reaction in individuals repeatedly exposed to them.

Editors note: This article is based on an Oct. 26, 2016, paper in Austral Entomology (Australian Entomological Society) titled Systemic and erythrodermic reactions following repeated exposure to bites from the Common bed bug Cimex lectularius (Hemiptera: Cimicidae). The paper can be found here. The following information is reprinted in PCT with permission of Stephen Doggett, Department of Medical Entomology, Pathology West Westmead Hospital, Westmead, Australia.

As always, pest management professionals should never offer medical advice to their clients. This article is provided for informational purposes only.

Bed bugs (Cimex spp.) readily bite humans, producing a range of cutaneous reactions. This article documents systemic reactions in two patients following repeated bites from the common bed bug, Cimex lectularius. Both patients had previously fed bed bugs on themselves without any serious complication, however, upon feeding a new batch of the insects, they subsequently developed systemic urticarial reactions. Both were admitted to an emergency department for treatment and subsequently made a full recovery.

Patient 1 fed 40 to 50 bed bugs on himself and after eight minutes, he developed itch, swelling of the face, lethargy, profuse sweating and widespread wheals on the torso and limbs. The reaction disappeared in five hours after treatment with systemic prednisone and antihistamines. Patient 2 developed a similar reaction after feeding five to six bed bugs on himself. In this case, the patient also developed chest tightness and breathing difficulties. Following a similar treatment, symptoms disappeared in four hours.

In light of the increasing exposure of this insect to the general public, systemic reactions in patients may present more commonly to the medical practitioner. This report demonstrates how bed bugs can be a serious threat to the health of the community. If people are constantly exposed to bed bug bites (especially in low-income housing), then the effects can be extremely harmful to the individual.

DISCUSSION. There are a limited number of published cases of systemic reactions to bed bugs and symptomology has been ill defined. Consequently, these reactions can create a diagnostic dilemma for health-care professionals. A diverse number of dermatological differential diagnoses exist. Multiple bed bug bites are typically characterized by a cluster or linear distribution of erythematous macular lesions and can progress to wheals and widespread urticarial (Doggett & Russell 2009).

Although rare, systemic reactions can involve widespread pruritis, asthma, anaphylaxis and fever (Doggett et al. 2012). There is increasing evidence to support sensitization after initial exposure to bed bugs with the latency period between bed bug bite and cutaneous reaction decreasing substantially between subsequent bites (Reinhardt et al. 2009).

In the case of the 28-year-old male, he had been exposed to bed bug bites since November 2012 and has developed progressively more severe cutaneous reactions from each subsequent bite.

CONCLUSION. Physical impacts of bed bug bites are of growing concern, and there has been a surge of legal disputes throughout the western world recently. State and local governments have been overwhelmed with complaints by residents in regards to bed bug infestations, which are at times resistant to pest control measures (Aultman 2013). Bed bug infestations have become a particular problem among the socially disadvantaged, where infestations often go untreated, leading to massive bed bug populations and ongoing bites. Therefore, patients with systemic reactions may increasingly present to medical practitioners.

During its lifetime, a bed bug will go through three distinct stages. The first stage is the egg. A bed bug egg measures roughly one millimeter which is approximately the size of two grains of salt next to each other. The egg itself is oval and is opaque white in color. This stage lasts from ten days to approximately two weeks. The next stage of the bed bugs life is the nymph stage. In the nymph stage the bed bug begins to feed. In fact, a bed bug must feed on blood at least once before it is able to molt and go on to its next nymph phase. The nymph stage can be broken into five phases because the nymph will molt five times before reaching maturity. In each of these phases the bed bug will grow approximately a half of a millimeter. At the first nymph phase they will be one and a half millimeters long, growing to four and a half millimeters long by the fifth stage. The nymph stage of the bed bugs life cycle takes from five to six weeks. The last stage of the bed bugs life is the mature bed bug stage. At this point a bed bug will both feed on human blood as well as have the ability to reproduce.
