AN ANTIFEEDANT AGENT WITH INSECTICIDAL EFFECT

摘要

Acetophenone, ethyl butyrate and 2-phenyl ethanol were used as additives to media on which young adult Tribolium castaneiim (Herbst) and Lasioderma serricorne (Fabricius) were cultured for 65 days. A mixture of the three flavour volatiles deterred the insects from feeding well which subsequently affected the growth of the insects and after just 65 days, all the insects died. But when the concentration was increased, the insects became weak and died within a few minutes. Similar findings were observed with direct exposure to the mixture. Thus a mixture of the three flavour volatiles could be used in the formulation of effective control measures for the two insect pests both as an antifeedant and insecticide.
