| Abstract | ||||
| Quick lime, Beauveria bassinet, Metarhisium anisopliae and Hostathion [triazophos] were used as poisonous baits mixed with molasses and wheat brain (2: 1: 4) against Anacridium aegyp < /span>tium adults under laboratory and field conditions. Quick lime was the most efficient material against A. aegyp < /span>tium after 72 hr. when used at the quantity of 1.75 kg and achieved 90% mortality, followed by both M. anisopliae at the concentration of 1.75 x107 spores /ml., Hostathion at the concentration of 1.75 ml/l and B. bassinet at the concentration of 1.75 x107spores /ml .compared to the control. Starved adults were exposed to the concentrations of LC50 without plants in the laboratory for 24, 48 and 72 hr. Quick lime also achieved higher mortality (54%) after 72 hrs. compared with any entomopathogen and Hostathion. In the field trails, A. aegyptium were exposed to double concentrations of the quick lime, fungal entomopathogen, and Hostathion for 2, 4 and 6 days. Fewer grams of quick lime and Hostathion insecticide semi-hard cake were consumed and achieved higher mortality after 6 days compared with the two other biological agents and the control. | ||||
