Repellency of botanicals against S. zeamais

What is it about?

This paper reports how some botanicals in the form of leaf powder, methanolic and ethanolic extracts exhibited repellent actions against the maize weevils infesting sorghum grains. Findings of this study reveal that E. balsamifera, L. inermis, M. hirtus and S. obtusifolia were repellent against the weevil and could be used to protect sorghum grains against the insect infestations.

Why is it important?

Botanical repellency against insect pests is one of the important criteria used for assessing ability to protect grains from infestations during storage. This paper shown how some botanicals could be used to repel S. zeamais away from sorghum grains so that the insects might not result in any infestation and hence a reduction in post-harvest losses.
