Cimex lectularius, or the common bed bug, is a species of Cimicidae. Its primary hosts are humans, and it is one of the world's major "nuisance pests." Although bed bugs can be infected with at least 28 human pathogens, no studies have found that the insects are capable of transmitting any of these to humans. [1]
Bed bug bites are caused primarily by two species of insects: Cimex lectularius (the common bed bug) and Cimex hemipterus, found primarily in the tropics. [3] Their size ranges between 1 and 7 mm. [7] They spread by crawling between nearby locations or by being carried within personal items. [2]
The Cimicidae are a family of small parasitic bugs that feed exclusively on the blood of warm-blooded animals. They are called cimicids or, loosely, bed bugs, though the latter term properly refers to the most well-known member of the family, Cimex lectularius, the common bed bug, and its tropical relation Cimex hemipterus.

The evolutionary origins of traumatic insemination are disputed. Although it evolved independently in many invertebrate species, traumatic insemination is most highly adapted and thoroughly studied in bed bugs, particularly Cimex lectularius. [1] [3] Traumatic insemination is not limited to male-female couplings, or even couplings of the same ...
Bed bug nymph, Cimex lectularius, engorged with human blood. Chagas disease is a modern-day tropical disease caused by Trypanosoma cruzi and transmitted by kissing bugs, so-called because they suck human blood from around the lips while a person sleeps. [92] The bed bug, Cimex lectularius, is an external parasite of humans. It lives in bedding ...
Not all species of insects have frontal sutures, but in those that do, the sutures split open during ecdysis, which provides an opening for the new instar to emerge from the integument. The frons is that part of the head capsule that lies ventrad or anteriad of the vertex. The frons varies in size relative to the insect, and in many species ...
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
