Abstract

Five esters, butyl acetate, allyl acetate, ethyl acetoacetate, isopropyl acetate and propyl acetate, were screened as fumigants in the laboratory for 24 h at 27 (±2) °C against the adults of __Rhyzopertha dominic__a (F), Sitophilus oryzae (L) and Tribolium castaneum (Herbst). Of the compounds tested, allyl acetate was the most toxic, with LD~99~ values of 7.56, 12.81 and 11.42 mg litre^−1^ against R dominica, S oryzae and T castaneum, respectively. Tests with allyl acetate against mixed‐age cultures of Cryptolestes ferrugineus (Stephens), Oryzaephilus surinamensis (L), R dominica, S oryzae and T castaneum revealed that doses of 50–150 mg litre^−1^ with 24–120‐h exposures were necessary to achieve 100% mortality of all life stages. Cryptolestes ferrugineus was the most tolerant insect tested, whilst R dominica was highly susceptible. The insect toxicity data indicates that allyl acetate has potential as a fumigant of stored food grains. Copyright © 2004 Society of Chemical Industry
