They normally inhabit houses, restaurants, hotels, bakeries, food stores and also railway compartments and ship holds.
Cockroaches are nocturnal insects which remain hidden during the daytime in cracks, holes or crevices of kitchens, godowns, hotels, public toilets, neglected bags, boxes and other articles but emerge at night so that you can obtain their nutrition. They may be fast runners and run quickly on being disturbed. Cockroaches likewise use their wings to fly as a way to get away from their predators. Body colour varies from brown to brownish black. Is dorsoventrally flattened measuring 3-5 cm in length. Mouth bears mandibulate type of mouth parts. Eyes are compound like other arthropods suited for mosaic vision using a single ocellus. Antennae bear around 100 segments and therefore are filiform healthy. Pronotum is characteristically large in the dorsum with the head like a hood. Forewings are somewhat thickened and are designated as tegmina as the hind wings are membranous and fan shaped. Legs are cursorial. The male is identified by the use of a couple of styli about the last abdominal segment known as sternum. Females bear a lower life expectancy ovipositor about the seventh abdominal segment. External genitalia of male are asymmetrical healthy.

The breeding season for cockroaches originates from March-September where they remain very active. Copulation is followed by egg laying. Eggs are laid in bag like structures known as ootheca that happen to be deep brown in colour. Oothecae are marked by sculptured patterns this will let you definite shape which is sign of a species. The quantity of eggs within an ootheca varies from 15-40 arranged in double rows. Formation of ootheca takes several days and quite often may be found attached to the substratum. Female lays around 100 oothecae in her overall expected life each containing 16 eggs. The hatching of eggs is determined by the temperature and humidity in the environment. They hatch after 35 days in summers but take 100 days during winter. The larval development is also dependent upon the weather conditions. Nymphs or perhaps the larvae become adults in A few months in summers but may take Two years to get adults in winters. The roll-out of nymphs into adults is of hemimetabolous type and they also shed their cuticle during moulting. 10-13 moults have already been notice within the life reputation cockroaches. Under favourable conditions 2-3 generations happen in per year otherwise only a single generation is available.
Cockroaches are omnivorous and feed on many different food materials. They're dirty, distasteful and odoriferous creatures and so are attracted towards garbage, food stuffs consumed by humans. They enter any food material consume it, discolour and spot it with faecal material and leave behind a foul smell. Also, they are generally known as transmitters of some diseases like tuberculosis, cholera, leprosy, dysentery and typhoid. Infestion of cockroaches in homes can be prevented by maintaining all of the pipelines, safety tanks, tightly sealed. Food stuffs must be completely covered. Insecticides can be employed in order to control them. Cockroaches could be attracted perfectly into a eating place after which may be killed. All the crevices and cracks from the houses needs to be sealed.
