Laboratory evaluation of certain insecticides against pigeonpea pod borer, Maruca vitrata Geyer

摘要

The relative efficacy of selected new and eco-friendly insecticides against the 3rd instar larvae of Maruca vitrata showed that indoxacarb and spinosad were highly effective and were at par with conventional insecticide, endosulfan. The two bio pesticides, namely Bacillus thuringiensis and Metarhizium anisopliae were moderately effective while botanical pesticide, neem fruit extract was ineffective against M. vitrata.
