Nature of Damage and its Management of Fall Armyworm (Spodoptera frugiprda) on Maize Crop: A Review

Abstract

Fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a polyphagous pest which is arising as one of the major threats to agricultural crop production. It has around 80 host species that cause severe damage to cereals and vegetable crops. This pest was first discovered in Africa (2016) and first collected and reported in Madhya Pradesh at Research Farm RVSKVV, Gwalior of the August Month in2019-20. The S. frugiperda larval are found in newly leaves, leaves whorls, tasseling or cobs according to their growth stages. Scrape leaves, pin hole symptoms due to early larval stage and pane window symptoms whereas in the later vegetative stages due to larval of fall armyworm, damage results in skeletonized leaves and seriously windows whorls. Whereas weather condition for insects firm is good for pest could cause about 100% losses in maize crop but not control in the time. Normal investigation, push and pull method, light traps are used, common botanical pesticides are available of neem locally available materials of ash and several suggested chemical pesticides with dose can be used for the management of S. frugiperda. In present a vital requirement for development of eco-friendly environment, cost-effectively and collectively adopted IPM strategies to easily the impacts of the S. frugiperda.
