dc.description.abstract	Mechanism of egg spacing behaviour and the olfactory response towards the oviposition marker in cowpea weevil Callosobruchus maculatus (F) Brazil strain was investigated. An ether soluble chemical substance (oviposition marker) secreted at the time of oviposition appears to be largely responsible for uniform egg spacing. The presence of this chemical is mediated by contact chemoreception. The study demonstrated that the adult females have the ability to distinguish their own oviposition markers and appear to ignore the oviposition markers deposited by o flier females in further oviposition on egg-laden seeds.	en_US
