The bioefficacy of insecticides mixtures against chilli thrips and mites were evaluated at College of Agriculture, Vellayani and Kalliyur Panchayath,Thiruvananthapuram, Kerala. Fipronil 40% + imidacloprid 40% WG @ 175 + 175 g a.i ha-1 was found to be effective in controlling both thrips and mites simultaneously followed by betacyfluthrin 8.91% + imidacloprid 19.81 % OD@ 15.75 + 36.75 g a.i ha-1. Spiromesifen 22.9 SC @ 96 g a.i. ha-1 was found to be effective in reducing chilli mite population alone. The leaf curling symptom due to the feeding of mites and thrips was least in spiromesifen and Fipronil 40% + imidacloprid sprayed plants.
