Cimex lectularius is a pest species in the Cimicidae family. It is a major nuisance pest in the world and its primary host is human. It produces alarm pheromones and has a dorso-ventrally flattened thorax.
Cimex lectularius
The bedbug Khatmal Cimex lectul-arius is a dorso-ventrally flattened insect that is about 5 mm long and 0.5 mm wide. It has long antennae that are made up of four segments. It has compound eyes on both sides of the head. Its body is sunken in the middle, and the head is partially enclosed in the body.
The family Cimicidae has approximately 100 species and is distributed around the world. They are ectoparasites of birds, bats, and humans. In some parts of the world, Cimicidae have become a major nuisance pest. In some regions, Cimex lectularius can become an incidental host for humans.
A number of scientists have tried using insecticides to control the population of these creepy crawlers. While these products have been effective at preventing and eradicating these insects, they have not been 100% effective. If a person is infested with these bugs, it’s essential to take measures to eliminate them from the home.
Khatmal Cimex lectul-arius is a widespread pest that eats human blood. While the bug is not known to transmit diseases, it can leave an unpleasant welt on the skin. The Environmental Protection Agency, Centers for Disease Control and Prevention, and United States Department of Agriculture consider this insect a public health pest.
Alarm pheromones
Alarm pheromones, also known as “buggy” odors, are a type of chemical produced by mosquitoes. These scents are most apparent when several bugs are confined together. Researchers have used different chemicals to study mosquito alarm pheromones.
In a study, a blend of the alarm pheromones and a desiccant was effective in driving bed bugs out of their harborages. It was found that alarm pheromones also enhanced the effect of desiccants. This is because alarm pheromones trigger the bed bugs to disperse, which decreases their survival rate.
The pheromones were tested on first-instar nymphs and adult females. Their effectiveness was evaluated using water loss rates after 24 h of exposure to the blend. The most effective blend was determined by comparing the effectiveness of the different compounds.
The alarm pheromone contains two major active ingredients: (E)-hexenal and (E)-2-octenal. The alarm pheromones are released to warn other bed bugs. The alarm pheromones can be triggered by unusual or unfamiliar touches, light, or even high levels of carbon dioxide/wind. The pheromones are detectable by the antennae of bed bugs.
Dorso-ventrally flattened insect
Bedbugs are small to medium sized insects with dorso-ventrally flattened bodies. They are brownish in color and lack wings. Female bedbugs lay about five eggs per day, in a sheltered location. The eggs hatch after about four to twelve days. Bedbugs have five nymphal stages, each requiring a blood meal. The fifth stage develops into an adult bed bug.
Bedbugs are members of the Cimicidae family, which also includes the minute pirate bugs. These bugs are obligate blood feeders and live inside the skin of their hosts. They have specialized organs for feeding. The genus includes 22 species, with 12 genera exclusively associated with bats and nine species associated with birds. Three species are associated with humans.
Three-segmented thorax
Bed bugs are classified as Hemiptera. There are two types, the common and the tropical. The common bed bug has a three-segmented thorax and an expanded lateral margin. The tropical bed bug, on the other hand, has a two-segmented thorax with flat extreme margins.
Histamine-binding heme protein
Researchers from the UK Department of Entomology have identified a novel Histamine-binding heme-protein in Khatmal Cimex lectullarius. The team analyzed the excretion of the histamine-binding protein in different life stages and populations of the insect. They also studied the effect of feeding on blood on histamine levels.
The study also discovered that bed bugs produce large quantities of histamine, which may be hazardous to humans. Histamine is a naturally occurring chemical in the human body that may cause inflammation and alert the immune system to threats. Excessive histamine is linked to respiratory problems, headaches, and gastrointestinal disorders.
Airborne aggregation pheromone
The airborne aggregation pheromeromone of the bed bug Cimex lectularius is a potentially valuable chemical lure. The aggregation pheromone is composed of five volatile compounds and is highly effective for attracting and arresting bed bugs. It can be detected in the air with the help of an olfactory detection device, and is used for detecting infestations in homes and commercial buildings.
The pheromone is also used to detect bed bugs. Several products have been developed to detect and kill bed bugs, including pheromone baits and gels. These products are not only effective for bed bug detection, but they are also safe for the environment.
Bedbugs feed on humans and other mammals, and have evolved to feed on birds close to humans. Several specialized lineages of these insects have become significant pests. Khatmal has the ability to spread through the air and attract a variety of animals.
Aggregation is an important feature of bed bug biology. Bed bugs are often found in large groups, consisting of both sexes and all stages of development. About 30% of a reproducing colony is comprised of aggregations. Aggregation is mediated by airborne and contact aggregation pheromones, and these pheromones decrease with hunger.
