Trehern & Pichone , 1972). Paint over the entire head (except mouth appendages) causes cockroaches to “free-run” in 24 hour light/dark cycles (LD 12∶12): the paint, therefore, blocks the normal pathway of light signals which otherwise would entrain the rhythm.

The Suspend SC contains an active ingredient called Deltamethrin, which poisons the roaches’ central nervous system, where their nerve cells become overly excited which causes paralysis and eventual death. This affects the central nervous system of the cockroach and kills it as quickly as possible. This paralyzes the front legs of the cockroach. In cockroach, sexes are separate, so dioecious. 2) The crucial part of this experiment is the dissection. The mirid bug Apolygus lucorum (Meyer-Dür), a polyphagous pest, is dependent on olfactory cues to locate various host plant species and mates. It comprises of the following components.
