The role of Cryptolaemus montrouzieri as an effective predator of Paracoccus marginatus Williams and Granara de Willink was often doubtful. Natural colonisation of C. montrouzieri was observed on papaya at Sathyamangalam (Tamil Nadu). The number of larvae were 18 to 30 per leaf. The massive colonisation of C. montrouzieri, will help in its effective utilisation against P. marginatus.
