Abstract

Capric acid added to a food – whole wheat flour and dried brewers’ yeast – to constitute 2.5% or more of the foodstuff killed all Tribolium confusum Jacquelin du Val within 8 weeks. Lesser amounts of capric acid resulted in different degrees of mortality. By the end of 4 weeks similar results were inevitable when varied levels of capric acid were added to two representative dehydrated foods, tapioca pudding and macaroni and cheese. This uncustomary use of a long-recognized insecticidal fatty acid has some merit: for immixed with foodstuff it can control insect pests, and yet it, as a natural constituent of milk etc., is no stranger to metabolic systems of higher animals, so probably is not too hazardous to humans.
