A comparative study between diapaused Pectinophora gossypiella (Saunders) male and female larvae from five cotton varieties (Giza 70, 86, 87, 88 and 92) cultivated in Kafr El-Sheik governorate and the active laboratory 4th instar larvae, in the biochemical contents (triglycerides, free fatty acids and total proteins) and the metabolic enzymes (alkaline phosphatase, L.D.H., GOT and GPT), showed high significance in Triglycerides, free fatty acids in male and female of some varieties of diapause larvae than with the active larvae. While, the content of total protein was high in diapause male larvae of Giza 88 followed by Giza 70 and Giza 92 and was low in all female diapause larvae. Alkaline phosphatase, L.D.H. and GPT were higher in the active larvae than the diapause.
