Efficacy of the New Chemistry Pesticides on Nymph and Adult Population of Whitefly Bemisia tabaci Gen. and their Effect on Naturally Existing Beneficial Fauna of Cotton in Punjab, Pakistan

This study was conducted at Lodhran (Punjab, Pakistan) against cotton whitefly Bemisia tabaci Genn. (Hemiptera Aleyrodidae) in the field of a farmer. Modern insecticides, relatively safer to the natural beneficial fauna, commonly available and used by the farmers, viz. , buprofezin, Flonicamid, spintoram, pyriproxyfen, diafenthiuron, acetamiprid, spirotetramid were tested against a control treatment where no action was taken at all. The objective was to screen out the effective chemicals which are also safe for naturally existing beneficial fauna so that these could be included in effective IPM of whitefly. Two applications of the treatments were made in RCBD with 10 days interval.
