The word cockroach is rooted in the Spanish cucaracha. The cockroach is characterizable by a flat oval body, long threadlike antennae, and a gloss black or brown leathery integument. The head is aimed downward, and the mouthparts point backward instead of forward or downward as is the case with almost all other insects. The male often has two pairs of wings, while the female, who in some species, is wingless or possesses vestigial wings. The female produces eggs in egg cases (known as oothecae). These are sometimes held coming from her body or could be glued in protected places. After the female deposits an egg case, the soft, white nymphs emerge. As their exoskeleton solidifies, it turns brown in hue. The form and big size (some species demonstrate a wing measurement of longer than 12 cm [4.7 inches]) of cockroaches have turned them into a singular objective in the biological laboratory.
The cockroach takes a warm, humid, dark living and is often located in tropical or other mild locations. Just a couple species have become pests. The insect harms more material than it consumes and has a unpleasant odour. The food preference of the roach, which is both plant and animal products, goes from food, paper, clothing, and books to dead insects, including bedbugs. Insecticides should be used in roach termination.
The American cockroach (species Periplaneta americana) is 30 to 50 mm long (up to about 2 inches), reddish brown, and lives outside or in dark, heated indoor areas (e.g., basements and furnace rooms). In adult life, a time of about 1.5 years, the female generates 50 or more oothecae, each holding usually 16 eggs that hatch after 45 days. Nymphal life lasts from 11 to 14 months. The American cockroach, originally from tropical and subtropical America, possesses well-developed wings. However, the majority of species are rarely good at flying.
The German cockroach (Blattella germanica), a common pest in houses and is often erroneously labeled a waterbug, is light brown with two dark stripes on the prothoracic region. The female produces the ootheca three days from mating and carries it for generally around 20 days. Because it is tiny (about 12 mm [less than 0.5 inch] long), this cockroach frequently can be introduced into residences in grocery bags and boxes; it has been taken across the globe by boat. Three or more generations could breed yearly. This cockroach, abundant around the water pipes of the Croton Aqueduct in New York City, is called the Croton bug.
The brown-banded cockroach (Supella supellectilium) closely resembles the German cockroach but is even smaller. The male has completely developed wings and is brighter in colour than the female, whose wings are short and nonfunctional. Both sexes have two light-coloured bands over the back. The adult life span is around 200 days, and there might be two generations in a year. Eggs may be deposited in clothes, wood molding, or cracks in the floor. With the introduction of heated buildings this cockroach became more common in cooler areas.
The Oriental cockroach (Blatta orientalis) is thought to be one of the most disgusting of household pests. It is oval, shiny black or dark brown, 25 to 30 mm (1 to 1.2 inches) long, with a life cycle resembling that of the American cockroach. The male has short, fully developed wings, and the female possesses vestigial wings. This cockroach has been taken by vehicles of trade from its Asiatic origins to every temperate regions.
Wood roaches are non-domestic pests. Parcoblatta pennsylvanica, the common wood cockroach, is found beneath logs and stones in northern latitudes. The male and female are so unlike in appearance that they were first considered individual species. The male, 15 to 25 mm (0.6 to 1 inch) long, has wings that expand beyond the abdomen; the female is smaller and possesses much shorter wings. Cryptocercus punctulatus eats wood with the help of some protozoans in its digestive tract.
