In-vitro evaluation of biopesticides (Beauveria bassiana, Metarhizium anisopliae, Bacillus thuringiensis) against mustard aphid Lipaphis erysimi kalt. (Hemiptera: Aphididae)

Abstract

In this study efficacy of bio-pesticides was evaluated against mustard aphid Lipaphis erysimi in-vitro condition at the Department of Entomology, University of Agriculture Faisalabad from July 2015 to May 2016. Mustard aphid Lipaphis erysimi (Homoptera: Aphididae) is the limiting factor of qualitative and quantitative losses by attacking and hurting the leaves and pods in growing areas of Pakistan and also develop resistance to some synthetic insecticides. Biopesticides are target specific, retard insect growth, metabolic process and has a less adverse toxicity to mammals. Five concentrations with three replications of each insecticide were used in several bioassays. The mortality data was recorded over a period of three days at 12h interval. Among entomopathogenic biopesticides M. anisopliae (83.23%) found most effective against mustard aphid followed by B. bassiana (78.33%) and B. thuringiensis (73%). Bio-pesticides can be used as a potential candidate for integrated pest management against mustard aphid after field efficacy.
