A field experiment to evaluate some IPM modules against major pests viz., Aphis gossypii, Myzus persicae, Bemisia tabaci and their natural enemies viz., coccinellids and spiders occurring in king chilli Capsicum chinense Jacquin was carried out during rabi (2014-16) at Jorhat, Assam. The results revealed that module M2 with seedling root dip treatment with imidacloprid 17.8 SL @ 40g a.i./ ha + growing of border crop (okra)+ spraying of imidacloprid 17.8SL @ 40g a.i./ ha at 20 days after transplanting at 15 days interval is the most effective in suppressing aphids and whitefly followed by lambdacyhalothrin instead of imidacloprid in both the seasons. The insecticidal treatment modules had a significant effect on the pest and the viral diseases, thereby increasing the yield, with maximum yield obtained in module M2 (3564.44 kg/ ha) and with a maximum cost-benefit ratio of 1: 4.85.
