What is a Cockroach?
The word cockroach is taken from the Spanish cucaracha. The cockroach is characterizable by a flattened oval body, long thin antennae, and a glossy black or brown leathery integument. The head is aimed downward, and the mouthparts point to the rear instead of forward or downward as is the case of many other insects. The male generally has two pairs of wings, unlike the female, who in some species, is wingless or appears with vestigial wings. The female produces eggs in egg cases (labeled oothecae). These are occasionally held protruding from her body or might be glued in protected areas. After the female generates an egg case, the soft, white nymphs emerge. As their exoskeleton solidifies, it turns brown in hue. The form and big size (particular species possess a wingspread of higher than 12 cm [4.7 inches]) of cockroaches have made them a significant area in the biological laboratory.
The cockroach enjoys a warm, humid, dark environment and is usually found thriving in tropical or other mild temperatures. Only a small number of species have become pests. The insect inflicts damage upon more material than it digests and has a unpleasant scent. The eating habits of the roach, which should be both plant and animal product, ranges from food, paper, clothing, and books to dead insects, especially bedbugs. Insecticides could be preferred in roach control.
The American cockroach (species Periplaneta americana) is 30 to 50 mm long (up to about 2 inches), reddish brown, and lives out of doors or in dark, heated indoor spaces (e.g., basements and furnace rooms). During its adult life, lasting 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, indigenous to tropical and subtropical America, has well-developed wings. However, most species are not usually great flyers.
The German cockroach (Blattella germanica), a common pest in houses and sometimes erroneously labeled a waterbug, is light brown with two dark stripes on the prothoracic area. The female deposits the ootheca three days post mating and carries it for about 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 gone between nations by ship. Three or more generations may breed yearly. This cockroach, abundant through the water pipes of the Croton Aqueduct in New York City, has become called the Croton bug.
The brown-banded cockroach (Supella supellectilium) is like the German cockroach but is a little bit smaller. The male has totally developed wings and is lighter in shade than the female, whose wings are short and nonfunctional. Both sexes have two light-coloured bands along the back. The adult life span is about 200 days, and there could be two generations a year. Eggs are be dropped 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 held as one of the filthiest 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 possesses short, fully developed wings, and the female has vestigial wings. This cockroach has been carried in vehicles of trade from its Asiatic origins to almost all the temperate regions.
Wood roaches are feral pests. Parcoblatta pennsylvanica, the common wood cockroach, habits under logs and stones in northern latitudes. The male and female are so varied in appearance that they were first believed to be different species. The male, 15 to 25 mm (0.6 to 1 inch) long, has wings that extend past the abdomen; the female is smaller and possesses much shorter wings. Cryptocercus punctulatus consumes wood with the assistance of particular protozoans in its digestive tract.
