N2  - Spread of invasive pests and diseases, which are often considered one of the largest constrain in the production of agricultural crops has impact negatively in global agriculture. Some of these pests have caused significant damage in the production of the commodities which has caused difficulty in the food security. Maize is an important cereal crop and staple food for many people around the world. The Fall Armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) can affect all stages of development in maize and is difficult to control (USAID, 2017). According to Montezano (2018) FAW larvae can reportedly feed 353 different plant species but in Nepal this pest is a major threat especially for maize crop. Maize (the most preferable host of FAW) is the second largest crop cultivated in the country in terms of area and quantity of production with the total area of cultivation of 954158 hectare and total crop production of 2555847 metric tons (AICC, 2019/20). Maize crop in Nepal is mainly cultivated as summer crop but with the increased irrigation facilities in river basins and plain areas, the year-round cultivation of maize crop is also increasing (Poudyal et al., 2001). For FAW to be established, the temperature during pre-monsoon, monsoon and post monsoon is highly favorable. According to CABI (2019), the climatic conditions in Nepal are suitable for the establishment of FAW populations, which could potentially cause upto 100 percent crop loss. Thus, the infestation of this pest possesses very high risk of food and seed insecurity especially in the mid hill region of Nepal. FAW has been reported in maize and sorghum field so far in Nepal. The yield losses from FAW in Africa have been reported ranging from 21 to 53% in maize (Prasanna et al., 2018). FAW has affected maize crop in all seasons. The average area affected by FAW is estimated to be 371835 ha (38.97%) and estimated loss caused by FAW is about 16.51 % in the affected area (PQPMC, 2021 unpublished compilation)
