The presence of males is still necessary because there is no recruitment without fertilization. It is known to be very mobile; its wings allow it to be quite a capable flier. The Florida woods cockroach, Eurycotis floridana (Walker), is native to the southeastern United States, where it is often referred to as a palmetto bug. Figure 4: Double Stem and Leaf of Grasshopper Body and Leg Length in cm. Because these species can tolerate the human environment, and are easily reared in laboratories, they are often used for various biological studies. Ecological Monographs 23: 79-126. 9, Drexel Hill, Pa. It is also an occasional invader of the home, but lacks effective flight wings and is slow moving. Functionally, the pronotum is a versatile tool that can serve as a shield, shovel, plug, wedge, crowbar, and battering ram. 1988, Hebard 1917, Atkinson et al.

Dead Cockroach on a tiled floor. Although the gland for the defensive secretion is present in the last nymphal stage, it does not produce the chemical until after molting into a reproductive adult (Stay 1957). These glands are lined with setae that present the secretions as an offering to the female to lure her into an appropriate copulatory position (Barth 1968, Farine et al.

(iii) It has spiracles (respiratory openings) on lateral side of the segments of thorax and abdomen for exchange of gases. As an alarm pheromone, low doses provoked strong escape reactions in nymphs and females, with reduced response in males (Farine et al. The adults have well developed cerci and tooth-like projections at the edges of the dorsal segments that approach the cerci. 1990). 9.

Every abdominal segment of cockroach consists of two lateral sclerite plates called pleura along with a dorsal terga and a ventral sterna. 1970, Smith & Whitman 1992). Dorsal view of nymphs. Cockroaches, especially the peridomestic species, are best known for their fast running. Both males and females of Microdina forceps have the anterior pronotal margins extended into a pair of curved spines, resembling the forceps of earwigs or the mandibles of staghorn beetles (Fig. Lateral-dorsal view of an adult Florida woods cockroach, Eurycotis floridana (Walker).

The genus Eurycotis has one other member present in the United States that is confined to the Florida Keys, Eurycotis lixa Rehn (Gurney 1959). In Geo-scapheini (Blaberidae), males often have conspicuous pronotal tubercles that are absent in the female, and have the anterior edge thickened and prominently upturned (Walker et al., 1994); Macropanesthia rhinoceros is named for the blunt, horn-like processes projecting from the surface of the pronotum in males (Froggatt, 1906). In species with strong sexual differences in pronotal morphology, dimorphism is likely related to sexual competition among males.

The American cockroach is the largest of the house-infesting roaches and a major pest in the United States. At the base of each antenna, on inner side, a small rounded and light coloured area called fenestra … Defense sprays of roaches. The ootheca has roles in gas exchange, mechanical protection and osmoregulation using the substrate; substrates with excessive water retention will lyse the ootheca from extended water absorption and substrates with insufficient water retention will cause the ootheca to dehydrate (Bell et al. Hindgut- It is also known as proctodaeum. (C) Male of Princisia vanwaerebeki, lateral view. 8—9. The ootheca may be dropped prematurely if the adult is startled, harassed or in danger. Because of the size of E. floridana and the specialization parasitoids often exhibit towards specific hosts, Evaniidae, a common family of cockroach parasitoids, is ineffective against the Florida woods cockroach (Deyrup & Atkinson 1993).
