TOXICOLOGICAL AND BIOLOGICAL STUDIES ON THE FLY,SYNTHESIOMYIA NUDISETA (WULP

ABSTRACTThe present work aimed to evaluate the toxicity of two volatile oils and four fixed oils and crude extracts, the two volatile oils are golden pillar, Cupressus macrocarpa and galangal, Alpinia officinarum, the four fixed oils are chicory, Cichoricum intybTreatment with the two volatile oils and the four fixed oils affects some biological aspects of S. nudesita. Significant reduction in pupation percent, adult emergence, fecundity and hatchability were observed. Also morphogenic aberrations were noticed liThe histological effects induced by oil treatments in the body wall were represent by the degeneration and detachment of hypodermis.The hisopathological effects that appeared in the mid-gut were vacuolation, degeneration of epithelium and muscularis. The histopathological effects in ovaries showed great reduction in the number of oocytes and their size, vacuolation in nurse cells, oopThe sublethal effects of plant oils on total carbohydrate, lipid, protein and protein fractions in third instar larvae of S. nudesita were studied. The results showed that both volatile and fixed oils have the same effect on carbohydrate content, as they
