Research and/or project statements There are five main areas to his research program: methyl bromide alternatives in flour mills, extreme temperatures, natural products, insect behaviour and biological control. He has examined: heat, cold, diatomaceous earth, sulfuryl fluoride and the combination of heat, phosphine and carbon dioxide to control insects in flour mills. He has done extensive work on the use of low temperature to control stored product insects. Studies on farms in storage facilities during the winter have demonstrated the ability of insects to become acclimatised to low temperatures. He has examined the use of natural products such as neem, pea extracts and diatomaceous earth to control stored-product insects in bulk grain and in food processing facilities. His work on insect behaviour has focussed on trap design and insect repellants. His work on biological control has focussed on the effects of natural products on stored-grain insect parasitoids and the use of Trichogramma to control Indian meal moth in warehouses and retail stores.
