The study was conducted to manage the population of aphids on wheat by augmentation of predators
(Coccinellids and C. Carnea). The release of predators showed significant control of aphids under natural
conditions almost at all the post treatment intervals. However, the plots where both predators were released
showed significantly minimum population of aphids. The population of predators showed negative and nonsignificant effect on the population of aphids at most of the post treatment intervals except coccinellids versus
aphids at 7 days after first release and aphid versus C. carnea at 7 and 15 days after second release, which
showed significant and negative correlation. The maximum increased (3.83%) in 1000-grain weight over control
was observed in those plots where both predators were released.
