A laboratory study was carried out to evaluate the sublethal impact of synthetic pesticide on the histology of midgut in Callosobruchus chinensis L. This study reviews the sub-lethal impact of cypermethrin on the histology of midgut in Callosobruchus chinensis L. The experimental insect was subjected to a given sublethal dose of the selected pesticide. The exposure did not cause immediate death of the pest, but had delayed and prolonged sublethal impact on its midgut histology. The exposure caused progressive destructives changes in the histology of midgut of the experimental insect. The exposure disrupted the circular and longitudinal muscles in the midgut of the pest. The well-developed columnar epithelium of the midgut was altered. The peritrophic membrane of midgut which is usually attached with gut epithelium got constricted and detached from epithelial lining. It got highly degenerated and clustered at the centre of the gut cavity. The result of this study clearly demonstrate that the synthetic pesticide under investigation displayed significant sublethal impact on the histology of midgut in Callosobruchus chinensis L. Further the result of this study reveals that the selected pesticide can be used to control population of the experimental pest provided applied in controlled manner.
