Abstract
The effect of sublethal doses of DDT, endrin, sevin, thiodan and parathion on the larval duration growth and survival, pupal duration and survival, adult fecundity and sex ratio and viability of the eggs, of Tribolium castanaum has been ascertained by rearing it in wheat flour media containing 4 to 5 graded sublethal concentrations of each insecticide. The developmental period of the larvae of T. castansum is prolonged as a result of the pressure of sublethal doses of the insecticides contained in the medium this prolongation is directly proportional to the increase in the concentration of the toxicant within the sublethal range and it is more pronounced in the case of DDT, endrin sevin and parathion, than thiodan.
