Radiation induced changes in the cuticular hydrocarbons of the granary weevil and their relationships to desiccation and adult mortality: Annual progress report, February 15, 1987 to February 14, 1988
Sitophilus granarius (L) is a major pest of stroed grains and is prone to irradiation treatment. There is considerable scope for use of radiation like Cesium-137 (as a source) as an alternative to chemical treatment for pest control. Study with regard to radiation damage and the effect of environmental factors like temperature and humidity on adult weevil mortality due to radiation effect is limited. Stored-grain insects live in an enviroment where liquid water is seldom available. Waterproofing and conservation of water by the insects is a critical factor for weevil survival. In some insects it has been noted that the rate of water loss through the integument has been associated with changes in the hydrocarbon composition of the epicuticle. Epicuticular hydrocarbons play an important role in preventing desiccation. Information on the effects of irradiation on epicuticular hydrocarbon of the adult weevils is limited. The present investigation sudies the after effects of radiation damage to granary weevil (Sitophilus granarius (L.) in terms of causing increased water loss from the body, weevil nortality and concommitant changes, if any, in the cuticular hydrocarbons that waterproof the insect. 23 refs., 22 figs., 7 tabs.
