Abstract

Fall armyworm arrived on the Indian subcontinent in May 2018 and now it has spread across  India, Nepal, Bangladesh, Sri Lanka and approaching more beyond South East Asia. Strong flying capacity, climate adaptability, and wide host range makes them a better colonizing agent than other species of armyworms. Despite maize being primarily infested  in this region, infestation on sugarcane, sorghum, cotton and cabbage have already been reported from India, Bangladesh and Sri Lanka. National agricultural research bodies  like ICAR, IIMR, NARC, BARI etc. as well as international organizations like FAO, CGIAR, CIMMYT and CABI are working at different levels in effort to develop managemen strategies to combat the pest. Since it is practically impossible to eradicate the pest now, it is essential to work for long term management and in keeping pest population below economically injury level. Reliance on synthetic pesticides only is a temporary way of dealing with the pest. Educating the farmers themselves about the pest and practicing integrated approach of management compatible and feasible in the region would be more sustainable. Identification and using native species of natural enemies, such as predators, parasites and parasitoids is the current need of research. The experiences of small holder farmers in Africa and South America in fall armyworm management might be relevant to South Asia.

Keywords:
Fall armyworm, South Asia, synthetic pesticides, agroecological approach, natural enemy.
