Abstract

Fall armyworm, Spodoptera frugiperda (J.E.Smith) (Noctuidae: Lepidoptera) is a highly destructive invasive insect pest and has become a serious pest on maize across India and other countries. It causes immense damage to leaf, so in order to manage this pest and to overcome health, environmental and resistance related problems due to indiscriminate use of insecticides effective and sustainable pest control eco-friendly approaches are tested here. Among the selected ecofriendly approaches Metarhizium. rileyi recorded least larval population with corresponding 51.35 and 60.60 per cent reduction over control in larval population during first and second spray, respectively and with least leaf damage of 27.92 per cent. This stood effective and superior to all the treatments in the trail. This was followed by Azadirachtin 3000 ppm, B. bassiana and pongamia oil. Comparatively lesser effectiveness was recorded in the treatment of sand and lime while highest larval population and leaf damage was recorded in untreated check.
