Abstract:
The present investigation were carried out at laboratory of the Department of Agricultural Entomology, College of Agriculture, Dapoli, Dist. Ratnagiri 415 712 (Maharashtra). To protect the kabuli gram grains from bruchid infestation either 4 cm or 6 cm layers of five different cereals viz., red rice, nachani, wheat, bajara and maize were put above the kabuli gram and 5 pairs of adults C. maculatus were released in each treatment. The bruchid was not able to cause any damage to all the five cereal grains. Treatments comprised of either 4 cm or 6 cm layer of nachani, red rice and bajara were found effective in protecting kabuli gram grains from bruchid infestation. These treatments recorded least adult survival duration, no probing movement, no egg laying on kabuli gram grains, no damaged grains, no adult emergence and no weight loss.
