English: Bombay canary, ship cockroach; Dutch: Kakerlac.
Blatta americana Linnaeus, 1758, America.
Grows to 1.1-1.7 in (28-44 mm) in size. Tegmina and wings developed in each ####es. Reddish-brown, with pale yellow zone across the fringe of the pronotum.
An vital cosmopolitan pest in tropical and subtropical areas, having been distributed by commerce to many areas of the world.
Its authentic residence was Africa, the place it's discovered generally each inside and outside human dwellings. In the United States it in all probability is present in all city areas. This species prefers a heat, moist habitat and in tropical and subtropical America is widespread open air and could also be present in dumps, woodpiles, sewers, and cesspools.
May fly brief distances every now and then. Gregarious and will construct up big populations. After spraying the partitions of a trickling filter plant in Florida, over 2.5 cu yd (2.three m3) of American cockroaches had been collected, and several other instances that amount died within the adjoining woods. Females produce a pheromone that may entice the male from as distant as 98 ft (30 m).
FEEDING ECOLOGY AND DIET
Probably omnivorous; identified to feed on human feces.
Five-year life-history examine underneath room situations in Lafayette, Indiana (64.4-80.6°F, or 18-27°C, throughout winter, with a most summer time temperature 95°F, or 35°C), discovered common period of larval growth to be 468 days for females and 551 days for males. Females lived, on common, 441 days and produced 58 oothecae (most of 90). Oothecae contained 16 eggs, and the incubation interval was 53 days. In one other examine performed at 86-96.8°F (30-36°C), larvae went by means of 9 to 13 molts. When reared in teams, females required 161 days and males 171 days to mature.
SIGNIFICANCE TO HUMANS
Together with the German cockroach, in all probability essentially the most im- portant cockroach pest. Many micro organism, viruses, fungi, and helminths, quite a few them pathogenic to man, have been discovered within the American cockroach.
