A comparative study of repellent effects of dichloromethane extracts of Lantana camara L. and Calotropis procera Ait. on Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae)
Abstract
Dichloromethane extract from Lantana camara L. and Calotropis procera Ait. were evaluated for their repellent effect on a stored grain pest, Tribolium castaneum (Herbst). Both plant extracts exhibited a significant repellency. The results indicated that Lantana camara showed 60% repellency against Tribolium castaneum as compared to Calotropis procera which showed 72% repellency during an exposure time of 24 hours at 8mg/ml concentration.
