Abstract:
The present investigation on seasonal activity of pod fly, Melanagromyza obtusa (Malloch) (Diptera: Agromyzidae) and its relation with agro-climatic conditions of eastern Uttar Pradesh in pigeonpea, NDA- 2 crop during Kharif, 2018-19 revealed that pod damage and grain damage per cent by pod fly attained peak level during 15^th standard week with 14.33 per cent and 18.98 per cent respectively. The activity of pod fly, M. obtusa showed that the larval population attained peak level during 8^th standard week with 8.66/100 pods and pupal population during 11^th standard week with 24.66/ 100 pods. The simple correlation between pod fly (larvae and pupae) with weather parameter revealed that maggot population showed non-significant positive correlation with minimum temperature and maximum temperature (0.279 and 0.111) and pupal population manifested significant positive correlation with minimum temperature (0.650) and maximum temperature (0.667).
