The experiment was conducted at Experimental Research Farm, Department of Agricultural Entomology, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, during the Kharif season of the year 2016-17 to study population dynamics of new insecticides against insect pests of chilli. The experiment was laid out in a randomized block design with 9 treatments replicated three times. The treatments comprised of fipronil 5 SC @ 1000 ml/ha, hexythiaziox 5.45EC @ 500 ml/ha, spinosad 45 SC @ 187.5 ml/ha, acetamiprid 20 SP @ 250 g/ha, fenpyroximate 5 EC @ 600 ml/ha, emamectin benzoate 5 SG @ 250 g/ha, spiromesifen 22.9 SC @ 250 ml/ha, diafenthiuron 50 WP @ 625 g/ha and untreated control. The observations on the effect of these insecticidal treatments on thrips, mites, white fly and fruit borer were recorded. The observations on population dynamics of thrips, mites, white fly and fruit borer also recorded. The infestation of thrips, Scirtothrips dorsalis Hood was initiated in the third week of August (33rd meteorological week) and remained continue up to fourth week of December (51st meteorological week) during 2016-17. The data on correlation between meteorological factors and thrips population revealed that the population exhibited a significant positive correlation with maximum temperature while the correlation was negatively non significant with evening relative RH and average rainfall. The whitefly, Bemisia tabaci Genn. appeared in the third week of August (33rd meteorological week) and continue up to fourth week of December (51st meteorological week). The population increased gradually and touched its peak in third week of October (42nd meteorological week). The population exhibited significant positive correlation with maximum temperature and evaporation whereas negative and non significant correlation with rainfall, morning and evening RH and minimum temperature. The mite population persist throughout the crop season from fourth week of August (34th meteorological week) and was continue up to fourth week of December (51st meteorological week). The population increased gradually and touched its peak in the third week of October (42nd meteorological week). The fruit borer population touched its peak in the fourth week of November and showed the negatively non significant correlation with rainfall, morning RH, evening RH and minimum temperature.
