ABSTRACT
Recently, great attention has been paid towards exploitation of Bio-rational insecticides in plant pest management in perspective of the public concern over the level of pesticide residues in food and environment causing health and ecological problems. The indiscriminate use of synthetics insecticides in crop protection has also led to development of resistant strains of pests and have adverse effects on non-target organisms including natural enemies and pollinators. Amongst bio-rational insecticides, neonicotinoids and insect growth regulators (IGRs) may be exploited as eco-friendly approach in crop pest management. We therefore, evaluated the effectiveness of nitenpyram, Clothianidin, Momentum (Mixture of Nitenpyram and Chlorfenapyr) and Buprofezin against brinjal whitefly (Bemisia tabaci Genn.). The crop was grown in a randomized complete block design (RCBD) with three replicates each having five treatments with control. Pre-treatment data were collected before 24 h and Post treatment data were collected after 24, 72, 168 and 336 h of each spray. In this manner, the data for three sprays were collected. The order of effectiveness in decreasing sequence was found to be Nitenpyram, Buprofezin, clothianidin and momentum (75%), (65%) (64%) and (63%), respectively against whiteflies’ population.
