Repellant effect of neem formulation and aqeuous extract of Melia azedarach on greenhouse whitefly (Trialeurodes vaporariorum Westwood, Hemiptera: Aleyrodidae)
Journal Title: Journal of Applied and Natural Science - Year 2016, Vol 8, Issue 4
Abstract
The present study assessed the repellence activities of two biopesticides viz. a formulation of neem, neem baan and aqueous extract of Melia azedarach (Dharek) kernels against crawlers of greenhouse whitefly Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae). The maximum repellency (22.07%) was recorded at 10 % concentration of dharek extract followed by Neem Baan at 0.0025 % concentration (18.33%). The minimum repellency (4.71%) was observed at 0.0005 % concentration of Neem baan. These results indicate a potential use of neem baan and aqueous dharek kernel extracts in management of greenhouse whitefly.
