HCH AND MALATHION INDUCED CHANGES IN REDUCING SUGAR LEVEL IN HEMOLYMPH AND FAT-BODY OF THE LARVA OF RICE-MOTH CORCYRA-CEPHALONICA STAINTON (LEPIDOPTERA, PYRALIDAE)

The present study reveals changes in reducing sugar level in haemolymp h and fat body of the larva of rice-moth C. cephalonica following trea tment with sublethal doses of HCH and malathion. In the control larvae , the reducing sugar level was 2.71+/-0.23 mg/g in haemolymph and 1.05 +/-0.1 2 mg/g in fat body while in insecticide (HCH and malathion) tre ated larval groups, a marked dose dependent (p < 0.05) enhancement in these levels occur in both the tissues. It is obvious that HCH (a chlo rinated insecticide) appears to have more physiological toxic effect t han malathion (and organophosphorus compound).
