The German cockroach, colloquially known as the croton bug, is a species of small cockroach, typically about 1.1 to 1.6 cm long. In color it varies from tan to almost black, and it has two dark, roughly parallel, streaks on the pronotum running anteroposteriorly from behind the head to the base of the wings. Although B. germanica has wings, it can barely fly, although it may glide when disturbed. Of the few species of cockroach that are domestic pests, it probably is the most widely troublesome example. It is very closely related to the Asian cockroach, and to the casual observer, the two appear nearly identical and may be mistaken for each other. However, the Asian cockroach is attracted to light and can fly like a moth, while the German cockroach cannot.
Ectobiidae is a family of the order Blattodea (cockroaches). This family contains many of the smaller common household pest cockroaches, among others. They are sometimes called wood cockroaches. A few notable species include:
The Asian cockroach, is a species of cockroach that was first described in 1981 from insects collected on Okinawa Island, Japan. It is a small species of cockroach, typically 1.3 to 1.6 centimetres long and tan to dark brown in colour with dark parallel stripes on the back of their heads. It is commonly mistaken with the German cockroach for their similar appearance. It is commonly found in the United States in and around houses.
The smokybrown cockroach is a large species of cockroach, winged, and growing to a length of 32–35 millimetres (1.3–1.4 in).
The brown-banded cockroach is a species of small cockroach, measuring about 10 to 14 mm long and the most well-known in the genus Supella. It is tan to light brown and has two light-colored bands across the wings and abdomen, they may sometimes appear to be broken or irregular but are quite noticeable. The bands may be partly obscured by the wings. The male has wings that cover the abdomen, while the female has wings that do not cover the abdomen completely. The male appears more slender than the female, the female appears wider.
Cockroaches are a paraphyletic group of insects belonging to Blattodea, containing all members of the group except termites. About 30 cockroach species out of 4,600 are associated with human habitats. Some species are well-known as pests.
Waterbug or water bug can refer to any of several things:
The death's head cockroach is a species of cockroach belonging to the family Blaberidae. It is often confused with the discoid cockroach, Blaberus discoidalis, due to its similar appearance. It is distinguished by jet black cloak-like marking on its wings and a skull-shaped, amber/black marking on its pronotum. The name death's head comes from the markings on the top of the pronotum: "cranii", which is Latin for "of the head", and "fer", meaning "carry" or "carrier". Due to their unique appearance and certain characteristics, they make an easy to care for pet or display insect for entomologists and hobbyists.
Blaberus giganteus, the Central American giant cave cockroach or Brazilian cockroach, is a cockroach belonging to the family Blaberidae.
Sex pheromones are pheromones released by an organism to attract an individual of the same species, encourage them to mate with them, or perform some other function closely related with sexual reproduction. Sex pheromones specifically focus on indicating females for breeding, attracting the opposite sex, and conveying information on species, age, sex and genotype. Non-volatile pheromones, or cuticular contact pheromones, are more closely related to social insects as they are usually detected by direct contact with chemoreceptors on the antennae or feet of insects.
Periplanone B is a pheromone produced by the female American cockroach, Periplaneta americana. It is a sexual attractant to male cockroaches, especially at short ranges.
Blattabacterium is a genus of obligate mutualistic endosymbiont bacteria that are believed to inhabit all species of cockroach studied to date, with the exception of the genus Nocticola. The genus' presence in the termite Mastotermes darwiniensis led to speculation, later confirmed, that termites and cockroaches are evolutionarily linked.
Schizodactylus inexspectatus is a species of dune cricket (Schizodactylidae) endemic to sand dunes of Çukurova and Göksu Deltas, Turkey.
Blattellinae is a subfamily of the wood cockroach family, Ectobiidae. It includes the global household pest Blattella germanica, the German cockroach, and a number of endangered species. It contains about 70 genera.
Blattella is a genus of cosmopolitan and wild cockroaches in the family Ectobiidae.
Dc1a is a potent insect-selective poisonous 57-residue peptide that is produced by the desert bush spider (Diguetia canities). It promotes the opening of voltage-gated Na channels (Nav) in German cockroach (Blattella germanica) by interacting with the paddle motif in domain II.
Nephridiophaga is a genus of single cell eukaryotes, now considered to be fungi, that pathogenically inhabit the Malpighian tubules of insects. Ivanic described the type species from honey bees.
