The activity of pod fly, Melanagromyza obtusa (Malloch) (Diptera: Agromyzidae) attained peak level during 46th standard week while the population of M. obtusa was minimum (31/100 pods) during 49th standard week. The peak level of weekly per cent parasitization (18.18%) was observed during 51st standard week while minimum level of weekly per cent parasitization (6.52%) was observed during 47th standard week. Simple correlation was worked out between M. obtusa population and weather parameters and it revealed that positive significant correlation with minimum temperature (r = 0.769). Correlation between parasitization and percent was not significant. The regression revealed that the various abiotic factors was found to be most influencing factor, which contributed (R2 = 0.885 and 0.863) 88.5 and 86.3 per cent variation in M. obtusa population and per cent parasitization, respectively.Keywords
