Abstract
The field experiment was conducted at Spices Research Centre, Shibganj, Bogra, Bangladesh during Rabi season of 2014-15 to develop an integrated management approach against thrips-mite complex of chilli. The treatments were five including control. Spraying of Chlorphenapyr (Intrepid 10SC) @ 1ml/litre of water + White sticky trap @ 40 traps/ha resulted the lowest thrips (0.86 thrips/leaf) and mite (0.97 mite/leaf) population with highest marginal benefit cost ratio (33.02). The highest percentage of thrips (87.02%) and mite (87.32%) population reduction over control with maximum red ripe chilli yield (12.72 t/ha) was also obtained from Chlorphenapyr + White sticky trap. Thrips and mite populations are negatively correlated with Chlorophyll Concentration Index of leaf. However, the lowest percentage of upward (19.05%) and dounward leaf curl (21.08%) was also obtained from Chlorphenapyr + White sticky trap treated plot followed by White sticky trap + Abamectin + Success (22.75% and 25.15%, respectively) while the highest percentage of upward (71.25%) and dounward leaf curl (82.38%) was obtained from untreated control. So, installation of sticky white trap along with spraying of Chlorphenapyr may be recommended for effective management of thrips-mite complex in chilli.
