Effect of katel-sous dust and clove powder and their mixtures on the cowpea seed

Abstract

The present work was carried out to evaluate the toxicity of katel-sous dust and clove powder and its combinations. Evaluation has been conducted on Callosobruchus maculatus (F.) adults to determine the toxicological effect and the changes in insect biology caused by these products. The results referred to the availability to use these products to control cowpea seed beetle and consider clove powder as spiracle-blocking insecticides. Clove powder and katel-sous dust and its combinations made a sharp reduction in the number of eggs laid and the number of adults emerged. Mixing clove powder with katel-sous dust was helping in using katelsous dust in pest management without any problems such as; its high concentration which caused suffering from the expensive costs and hardly remove the dust.
