Abstract

The toxic and biochemical effects of six medicinal plant oils (Pepperminent,
Marjorana , Lavender, Sweet basil, Speerment and Artemisia) on Sitophiius zeamais
were investigated in the laboratory. Marjorana hortensis oil was more toxic to the
insect than the other tested oils. The L050 treatment of all test oils caused depletion
in total proteins, lipids and carbohydrates . Disturbance (increase or decrease)were
found in amylase. transaminases(GOT& GPT) and acetylcholine esterase enzymes
