Abstract Mungbean varieties/genotypes viz., GM-06-08, GM-4, GM-08-01, GM-05-08, GM-04-02, GM-08-09, KM-10-1038, WGG-37, KM-10-1040, COGG-912, KM-10-1039, ML-1256, ML-1268, KM-10-1037 and K-851 were evaluated for their susceptibility to Callosobruchus maculatus. Among these ML-1268 suffered maximum apparent (12.70% and 47.68%, respectively) and real loss in weight (25.40% and 51.72%, respectively) after one generation and after four months of storage. Whereas, minimum apparent (3.09% and 34.52%, respectively) and real weight loss (7.00% and 38.72%, respectively) after one generation and after four months was observed in COGG-912. Comparative weight/volume ratio was highest in ML-1256 (1: 0.594) whereas, the least (1: 0.429) was observed in COGG-912. The % infested grains after four months, was significantly maximum (99.03%) in ML-1268 and minimum (83.20) in COGG-912. It was observed that seed width and seed weight had no correlation with oviposition. The genotypes ML-1268 was most preferred for the development of adult showing 9.60 emergence per ten eggs.
