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.
