This book is related to the predatory potential of biocontrol agent (Coccinelids) on different species of aphid. Results showed that the Coccinellids (without starvation) consumed more number of M. persicae than A.nerii. Coccinelids (with 24 hrs starvation) showed maximum aphid consumption on B. brassicae, followed by R. padi, S. graminum and M. persicae. The life duration of Coccinellids was maximum on A. nerii and B. brassicae (65 days) followed by M. persicae (64 days), S. graminum (58 days) and R. padi (56 days).
