Fall Armyworm ( Spodoptera frugiperda) Invasive Pest of Agriculture and Their Biological Control: A Review

Abstract

Spodoptera frugiperda is also known as fall armyworm, one of the important pests of agronomic and horticulture crops, and spread throughout the tropics and subtropics areas, threatening food security, economic advancement, and the lives of millions of cereal farmers. FAW is the world's major migratory pest, mainly damaging jade Rice, paddy rice, sorghum, sugarcane, cotton, pasture, and sugar beet more than 80 kinds of plants Although FAW has received extensive scientific attention in its home range in the Pakistan, chemical inputs play a key role in its mitigation, and biological control adoption is behind globally. Here, a quantitative review of the first report in Pakistan and different countries, potential risks of fall armyworm, collected and organized based on the monitoring, morphological, bio ecology, and geographical distribution of S. frugiperda invasive sites, further, the natural enemies of S. frugiperda, such as parasitic wasps, nematodes, pathogenic fungi, virus; Pheromones traps supporting technologies, Monitoring methods and suggestions, to study the potentially suitable areas of S. frugiperda. A risk assessment was carried out, the occurrence of this insect in Pakistan will affect my country's production industry Therefore, further develop relevant new technology research, strengthen the protection and utilization of natural enemies, and prevent the spread and disaster of S. frugiperda should be paid attention to in disaster-prone areas through the organic combination of biological control and chemical control.
