Abstract :
The aim of this study was to observe the influence of various intercrops on pod borers in black gram under rain fed condition. Among the different intercrops studied, marigold recorded the lowest mean population of spotted pod borer (0.74 larva/plant) and gram blue butterfly larva (0.88 larva/plant)and natural enemies like Coccinellids (2.68 beetles/plant) and spider population (1.73 spider/plant) was maximum in black gram intercropped with maize. The maximum equivalent yield was obtained from black gram intercropped with marigold (6.04 q/ha) followed by black gram intercropped with maize (5.24 q/ha).In conclusion marigold proved to be effective intercrop to control major pod borer and also enhance the population of natural enemies.
