Fall armyworm (FAW; Spodoptera frugiperda (J. E. Smith)) is emerging as the most destructive pest of maize in India since its report in May 2018. Its rapid spread to more than 90% of maize-growing areas of diverse agro-ecologies of India within a span of 16 months presents a major challenge to smallholder maize farmers, maize-based industry, as well as food and nutritional security. FAW has been reported from other crops as well like sorghum and millets with varied proportion of economic damage. In this review, the transboundary movement of FAW, role of ecology, its spread and damage are discussed. Management of FAW by developing and deploying various pest management tools is elaborated. The role of agro-ecological measures for reducing FAW damage with African experiences has also been highlighted.Keywords

The present study was conducted to identify male-specific active plant volatiles from maize against Chilo partellus. The gas chromatography-electroantennogram detector evaluation of volatile extracts collected from maize plant through dynamic headspace collection revealed the presence of six electrophysiologically active volatiles for male, viz. toluene, 2-ethyl-1-hexanol, 4-hydroxy-4-methyl-2-pentanone, 1,4-dichlorobenzene, p-isopropyl benzaldehyde (cuminaldehyde) and p-xylene. Electroantennogram analysis of selective synthetic volatiles against male moths revealed significantly higher response to geranyl acetate, cuminaldehyde, linalool and 2-ethyl-1-hexanol. Electroantennogram studies showed dose-dependent responses of male moths against geranyl acetate, cuminaldehyde, linalool and 2-ethyl-1-hexanol up to 50 mg, above which saturation of antennal response was noticed. These findings will help to study the synergistic activity of identified volatiles with pheromone compounds for developing more effective lure for C. partellus monitoring and mass trapping.Keywords
