dc.description.abstractIndia is the largest producer and exporter of chilli (Capsicum annuum) in the world and attack of insect pests is a major constraint in its production. Present study was conducted during kharif 2013 at Bharti Field Fresh Farm, Ladhowal, Ludhiana and during rabi 2014 at Department of Forestry and Natural Resources Research Farm, PAU, Ludhiana. In the present study population dynamics of insect pests of chilli, efficiency of sticky traps for monitoring alate insects in chilli ecosystem and effectiveness of various insecticides in managing the insect pest population was worked out. Forty one arthropod species were found to be associated with the chilli crop among which fourteen species were each of pests and natural enemies, twelve species of casual visitors and one species of pollinator. Order coleoptera occupied the maximum share (26.83%) in arthropod fauna recorded on chilli ecosystem. Diversity indices represented a highly diverse arthropod fauna which was evenly distributed and without dominance of any species during both the seasons. Peak activity period for aphid and thrips was recorded during October and May, for whitefly it was September and June, for mite peak population was during October and fruit borer demonstrated highest activity during May. Rectangular yellow sticky traps proved to be better in capturing alate insect pests of chilli as compared to the cylindrical traps. Among the various insecticide treatments tested Thiocloprid 21.7 % SC @ 200 ml/acre proved to be best for management of aphid and whitefly whereas Buprofenzin 25 EC @ 240 ml/acre was the best for managing thrips and mite. In case of fruit borer, Chlorantraniliprole 18.5 SL @ 50 ml/acre performed better than the other treatments.en_US
