| Abstract |
The activity of amino transferases and the histological structure of the integument were studied in the larvae of cotton leafworm, Spodoptera littoralis after treatment with the LC50 of chitin synthesis inhibitor, Flufenoxuron; Nuclear Polyhydrosis Virus and Bacillus thuringiensis var. kurstaki. Aspartate amino transferase (AST) and alanine amino transferase (ALT) were significantly decreased due to treatment with the three tested compounds. The decrease in amino transferases was more pronounced in flufenoxuron treatment than in the other two bioinsecticides. AST was more active than ALT in both non-treated and treated larvae. Flufenoxuron completely disrupted the formation of epicuticle and most of the endocuticular deposition of the late 6`" instar larvae. Treatments with the microbial agents slightly affected the three layers as compared to flufenoxuron.
