Abstract

Two species of predacious bugs, Eocanthecona furcellata (Wolff) and Andrallus spinidens (Fabr.) (Hemiptera:Pentatomidae) were found effectively preying on Spodoptera frugiperda (Smith) in organically grown maize from 28 to 56 days at GKVK, Bangalore. Population of E. furcellata in one square metre was more than A. spinidens during the 38th and 39th standard meteorological weeks. Adults and nymphs of both the species preyed on different stages of S. frugiperda larvae. These two species being initial colonizers has a potential in integrated management of fall army worm.
