| Abstract |
The biological and biochemical activities of the entomopathogenic bacterium, Serratia marcescens, that produced chitinase and the chitin synthesis inhibitory insecticide Lufenuron were determined using LCso values against S. littoralis (Boisd.). Treatment of sawdust as pupation medium with S. marcescens caused a significant increase in the pupal weight while, lufenuron significantly decreased it. Both adult emergence and malformation were significantly changed. Significant increase in chitinase and amylase activities was observed after 3 and 13 days of pupation in lufenuron- treated sawdust. S. marcescens caused a significant increase in the acid and alkaline phosphatases activity in pupal stage at the P day of pupation. Both S. marcescens and lufenuron caused a significant decrease in total carbohydrate contents during the pupal stage.
