Field experiment was conducted to examine the biology of Callosobruchus chinensis (L.) during summer and winter season considering green gram (variety-Pratap) and black gram (variety-KU301) as host plants. In green gram, the incubation period was 4.92±0.14 days and 6.24±0.13 days, larval period was 17.50±0.12 days and 23.57±0.18 days, pupal period was 7.53±0.09 days and 9.41±0.07 days, total developmental period was 29.95±0.21 days and 39.22±0.22 days during summer and winter respectively. In black gram, the incubation period was 5.46±0.12 days and 7.37±0.15 days, larval period was 18.28±0.08 days and 24.50±0.12 days, the pupal period was 8.17±0.07 days and 10.12±0.12 days, the total developmental period was 31.91±0.15 days and 42.08±0.21 days during summer and winter respectively. The data revealed that the developmental period was shorter in the summer season than in the winter season and also the total developmental period was longer in black gram as compared to green gram.
