    • Abstract

       

      In this paper quantitative estimations of free proteins, total carbohydrates/ glycogen and fatty acids from cockroach haemolymph and heart muscle are reported from normal and insecticide treated insects. High content of protein, carbohydrate/glycogen and fatty acids are found in the haemolymph and heart muscle of nymphal insects. Higher amount of carbohydrates/glycogen are found in adult males, while more protein and fatty acids were found in the females. After insecticide treatment, no sex variation was found in the percent depletion of metabolites. The difference in the depletion rates between nymph and adult was also insignificant. High percent depletion of the macro-molecules was found with insecticides which are found more toxic in bioassay studies. A correlation has been made between the rate of depeltion and insecticidal poisoning.
