The present study was undertaken to screen some plants belonging to family Lamiaceae against
Callosobruchus chinensis Linn.. Among fourteen important insect pests of stored grains, the pulse beetle C.
chinensis (Coleoptera: Bruchidae) is one such pest causing considerable damage to stored pulses. The eggs are
laid on the host grains; the larvae bore inside and after feeding and pupating emerge out as adults leaving
behind damaged hollow seed-grains. Looking into the hazards of chemical insecticides, there is an utmost need
to search for some alternate methods for protection against the damage caused by insects. The leaves of the
select plants viz., Ocimum basilicum, O. sanctum and Mentha spicata were employed in the form of various
formulations and mortality of the pest insect was assessed. A significant increase in mortality of C. chinensis
was observed in all the experimental sets as compared to normal and control sets during the present study.
When comparisons were made on the basis of ANOVA to compare the effect of the three plants on mortality,
it was found that the treatments of O. basilicum were superior over M. spicata and O. sanctum. The findings
overall suggest that all the three plants screened have a potential to be used against the pest C. chinensis and
can be employed as an alternate to chemical insecticides in household and storehouses to minimize the
infestation and damage caused by the bruchid.
