Abstract

The identification of alternatives to synthetic contact insecticides for the protection of durable foodstuffs has become a focus for research worldwide during the last 15 years. Candidate materials have included plants and plant extracts, inert dusts, insect growth regulators (IGRs) and microbial insecticides. The aim has been to find products to replace or enhance current control methods which rely on fumigation and insecticide application. Progress of research into the use of IGRs and microbial insecticides is reviewed. So far, only methoprene and Bacillus thuringiensis have been approved for application; details of their current uses are described. Other candidate materials are either still at the early stages of evaluation, or have been discarded because their levels of persistence are too high. In these cases, results from both laboratory and field trials are outlined. A few materials which have shown potential against agricultural, medical or veterinary insect pests have been included as they may be tested against storage pests in the future. Recent experience with fenoxycarb has indicated that prolonged persistence may render some materials unsuitable for use on stored foodstuffs. Inclusion of a material in this review does not imply its recommendation as a grain protectant. Novel insecticides are subject to the same stringent regulations as other pesticides, and their eventual approval will be a long and costly exercise. It is concluded that although IGRs and microbial insecticides show considerable potential for the protection of stored products, further research is needed.
