Abstract
The biology of Pod fly, Melanagromyza obtusa Malloch (Diptera: Agromyzidae) was studied during 2004 - 2005 in the laboratory of Department of Life Sciences, Manipur University, Imphal (Altitude: 790 msl and Latitude: 23.830N - 25.680 N) at a temperature of 17.39 ± 0.230C and 59.16 ± 0.39% relative humidity. The mean longevity of the adult pod fly was 6.59 ± 0.38 days. The incubation period varies from 2.5 to 3.5 days, the average being 2.99 ± 0.16 days. There were three larval instars which took 7.75 ± 0.53 days to enter into pupal stage. The pupal period lasted for about 9 to 13 days with an average of 11.38 ± 0.74 days. The life cycle of M. obtusa was completed in 41.74 ± 0.81 days.
Key words: Pigeon pea, pod borer, Manipur, metamorphosis, instar, life cycle.
