Abstract:
The laboratory experiment was carried out at laboratory of Department of Agricultural Entomology, College of Agricultural Dapoli, Ratnagiri Maharashtra during the year 2021-22. Eight different genotypes of cowpea were examined for the ovipositional preference and developmental period of C. maculatus. The overall study resulted that, the genotype SNJ-11 was observed to be the least preferred by C. maculatus for oviposition. Also, the minimum number of eggs (113.67) were laid on the same genotype with minimum hatching percentage (50%), adult emergence (27.00 adults). The genotype CP-13 was observed to be the most preferred by C. maculatus for oviposition. Also, the maximum number of eggs were laid (147.33) on same genotype with maximum hatching percentage (86.67%), adult emergence (49.72 adults) and the least adult longevity (7.40 days), total life cycle (22.63 days), respectively. The percent seed weight loss was also more (8.48%) in the CP-13 genotype.
