Abstract

Chemical analysi!': of total lipids and fatty acid composition of Trogodenna
granan'um was carried out to envisage Ihe effect of irradiated hosts diet on these
constituents. Total body lipids were affected indirectly by feeding of arvae on the
irradiated diet. The results showed that the fatty acids changed according to the host.
There were qualitative and quantitative differences In the individual fatty acid
composition between male and femsle.
Radialion was effective in changing the saturated and unsaturated fatty acid
concentrations especJally for 18: 2 and 18 : 3 which are essential for n rmalgrowth.
development and adult emergence.
In general, it coutd be concluded thaI ratty acid compcsluon affected indirectly
by feeding of larvae on the irradiated hosts diet, and consequcentry affect the
biological activity of insects.
