A biological and morphometrical study on pod fly, Melanagromyza obtusa Malloch (Diptera: Agromyzidae) was studied on pigeonpea early variety BDN-711 during Kharif-2017 at Entomological Research Laboratory VNMKV, Parbhani. The incubation period varies from 2.85 ± 0.03 days. Eggs were glistening white in colour and measured 0.75 ± 0.03, 0.20 ± 0.01 mm in length and width. There were three larval instars which took place within the pod and ranged from 8.22 ± 0.50 days to enter into pupal stage also the full grown maggot about 2.50 ± 0.05, 1.22 ± 0.03 mm in length and breadth. The pupal period ranged from 10.80 ± 0.22 days and measured 2.99 ± 0.10 and 1.25 ±0.06 mm in length and breadth, respectively. The life cycle of M. obtusa was completed in 28.59 ± 0.30 days. The mean longevity of the adult pod fly was 5.50 ± 0.45 days and average length and breadth of adult male fly 2.96 ± 0.08, 1.40 ± 0.09 however female fly was 3.20 ± 0.07, 1.55 ± 0.07 mm in diameter.
