The interaction of Coccinella transversalis Fabricius and lschiodon scutellaris (Fabricius) with the aphid, Aphis craccivora Koch was studied on green gram by estimating the prey and predator populations at weekly interval. Populations of both the predators had positive correlation with the aphid, attaining population peak simultaneously with their prey. The population decline of the prey was followed by their predators.
