| Abstract | ||||
| To evaluate the initial and bio-residual efficacy of Bancol on Schistocerca gregaria(Froskal), the last nymphal stadium were fed with 100 ppm on the 2nd-3rd day after moulting to analysis fat body and haemolymph on day 6. Two days before eclosion and on day 5 after final ecdysis a basic metabolism that affected Bancol treatment which are generated in the central nervous system was established. Derived a cessation of some metabolism in nymphs such as carbohydrates, protein, lipid and cholesterol. This is due to decrease of triglycerides reaching 56.82% and 80.28% for alkaline phosphatase. Reflectional, decreased the amount of food intake by 53.26% and pellets 49.32% besides 45.55% mortality in 5th instar. The change is due to interference with the central nervous system rather than to the altered feeding behaviour. Thus, the mortality of adult was 100% at 5th day old in spite of increase of metabolism in fat body (site of synthesis), but did no uptake to haemolymph. This is due to decrease of alkaline phosphatase reaching 85.03% and the enzyme of transaminase it was 77.93%. Consequently, it could be recommended to use the Bancot in frame of an integrated pest management system. | ||||
