Efficiency of quick lime is a natural control bait against Gryllotalpa Gryllotalpa, (Orthoptera: Gryllidae) under laboratory and field conditions [electronic resource].

Includes references.

Quick lime, Beauveria bassiana, Metarhisium anisopliae, and Hostathion were used as poisonous semi-hard cake which contains one of each of above-mentioned materials, sugar can molasses and wheat brain (2: 1: 4) against Gryllotalpa gryllotalpa adults under laboratory and field conditions. Quick lime was used at quantity of 1, 1.5and 1. 75 kg, Quick lime was the most efficient material against G. gryllotalpa after 72 hr. when used at the quantities of 1. 75 kg and achieved 95% mortality, followed by Hostathion at the concentration of 1.75 ml/1 (80%) and both M anisopliae at the concentration of 1.75 x107 spores /ml., (79%) and B. bassiana at the concentration of 1.75 x107spores /ml(65%).compared to the control. M anisoplia, B. bassiana were applied at the concentrations of lxl05, 1.5x106 and 1.75x107 spores / ml respectively. and Hostathion insecticide was applied at the concentration of 1, 1.5andl.75L Starved adults were exposed to the concentrations of LC50 without plants in the laboratory for 24, 48 and 72 hr. Hostathion.q and quick lime also achieved higher mortality (59 and 58%) after 72 hrs. compared with any entomopathogens and Hostathion. In the field trails, G. gryllotalpa 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
