Chilies are the most common spice cultivated in India. Chilli or red pepper Capsicum annum L. belonging to family solanaceae is an important spice cum vegetable crop commonly used in Indian dietary and are widely used in many cuisines to add spiciness to dishes. Guntur district in Andhra Pradesh is traditionally a chilli growing district with high input usage under monocropping conditions. The crop is ravaged by many insect pests right from nursery till harvest. Bhede studied the population dynamics and bioefficacy of newer insecticide against chilli thrips, Scirtothrips dorsalis (Hood). The incidence of thrips was highest during 40th meteorological week when the prevailing maximum minimum temperatures, morning-evening relative humidities, rainfall and bright sunshine hours Were 35.8°C, 18.0°C, 76%, 34%, 0.00 mm and 11 hrs., respectively, regression equations worked out indicated that the population decreased by 0.03, 0.04 and increased by 0.303 per unit of evening relative humidity, rainfall and bright sunshine hours, respectively. Application of phosphamidon 40% + imidacloprid 2% SP @ 700 g/ha was most effective for suppression of thrips population and also increased the yield of green chilli.
