Abstract
Abstract The efficacy of EC formulations of four insecticides was tested on Prostephanus truncatus and other storage pests in traditional maize stores in southern Togo. Deltamethrin (2 ppm) and the mixture of fenvalerate (7.5 ppm) and fenitrothion (37.5 ppm) satisfactorily controlled a wide range of beetles for more than ten months. The difficulties related to loss assessment of maize stored in husks was fully discussed. The quantity of frass caused by P. truncatus during infestation was a reliable indicator of the degree of infestation of the larger corn borer. There is a close correlation between the frass and dry matter loss, the number of P. truncatus and the total number of beetles. The application of the acquired experiences in the rural area will be the objective of further experiments.
