Abstract:
The laboratory experiments were conducted to study the biology of Callosobruchus chinensis Linnaeus on different varieties of chickpea viz., Digvijay, Phule Vikram, Phule Vikrant, BDN-9-3, ICCV-3137, ICCCV-3137, BDN-797 and ICCL-86111 under laboratory conditions at the Post Graduate Laboratory, Department of Agril. Entomology, College of Agriculture, Latur during 2022-2023. The significantly highest mean incubation period (6.13 days) was observed on BDN-9-3 and the shortest (4.84 days) in ICCL-86111. The significantly percent egg hatchability was found to be highest on ICCL-86111 (87 percent) while lowest on BDN-9-3. The significantly highest larval-pupal duration was noticed on BDN-9-3 (26.26 days) and the shortest on ICCL-86111 (24.12 days). The significantly highest adult emergence (75.00 percent) was observed on Phule Vikrant and the lowest in BDN-9-3 (50 percent). The significantly maximum adult longevity of male and female was registered in BDN-9-3 (10.00 days) and Phule Vikram (12.91 days). The significantly lowest longevity of male was observed in Digvijay (8.87 days) and the lowest of female in ICCCV-3137 (9.98 days). The highest sex ratio was registered in BDN-797 (1:1.34) and the lowest in Phule Vikram (1:1.02 and Phule Vikrant (1:1.02).
