B Chiranjeevi and NR Patange
The field biology of pod fly, Melanagromyza obtusa Malloch (Diptera: Agromyzidae) was studied during 2015-16 in the Research Farm, Agriculture Research Station, Badnapur (Vasantrao Naik Marathwada Krishi Vidyapeeth (VNMKV, Parbhani)), Maharashtra, India (Latitude: 19º 86' 66" N; Longitude: 75º 70' 72" E; and Altitude: +519.62 m MSL) when the maximum and minimum temperature; morning and afternoon relative humidity; and wind velocity ranged from 27.57 to 31.29 ºC and 12.14 to 14.57 ºC; 62.86 to 90.71 percent and 18.14 to 47.00 per cent; and 2.43 to 3.14 kmph. The incubation period of M. obtusa eggs varied from 4.0 to 5.0 days and the average being 4.4 days. The larval period varied from 8.0 to 11.0 days and took 9.5 days on an average to enter into the pupal stage. The pupal period lasted for about 8.0 to 11.0 days with an average of 9.6 days. The longevity of the adult pod fly varied from 6.0 to 11.0 days and the mean longevity was 8.4 days. The life cycle of M. obtusa has completed in 31.9 days.
