Abstract

The biology of Pod fly, Melanagromyza obtusa was studied during 2004–2005 at a temperature of 19.58°C and 70.15% relative humidity. The mean longevity of the adult was 6.59 ± 0.38 days. The incubation period varied 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.
