Maize (Zea mays L.) is a very important cereal crop of the world. In India, maize stands at third after wheat and rice both in acreage and production obtained. In Bihar, it holds a very special place among the farmers. In recent times maize crop is affected by both abiotic and biotic factors. Apart from diseases it is getting a major threat from a new insect pest called as fall armyworm (Spodoptera frugiperda Smith) Noctuidae: Lepidopteras. To study the extent of occurrence of Fall Armyworm besides the impact of different weather parameters on the occurrence of Fall Army Worm in Maize in Kosi Region of Bihar, a study has been undertaken at Bhola Paswan Shastri Agricultural College, Purnea. Under this project, block wise survey of farmers was done on both Kharif and Rabi season of maize. The nine different blocks of Purnea district, namely Kasba, Jalalgarh, Dhamdaha, B. Kothi, Bhawanipur, Dagrua, Amour, Purnea East and Rupauli were surveyed under the study. Survey data reveals that among the nine different blocks, maximum incidence of Fall Armyworm has been reported in Bhawanipur block (15%) followed by Jalalgarh, and B. Kothi (both reported 14% incidence) in Rabi. In Kharif also, the maximum incidence of FAW has been reported in Bhawanipur block (13%) followed by Dagurwa, whereas the minimum 5% of incidence of FAW in both the seasons during all the years of study has been reported from Kasba block. The study reveals that the average percent of damage to the maize crop due to the infestation of Fall Armyworm was in the range of (20 to 36 %) at farmer's field in Purnea and adjoining districts, resulting in the reduction of yield. Data showed that the larval population and percent damage has slowed down in the Rabi season, especially during the month of December and January, (15 Dec to 15 Jan) because of low temperature otherwise the temperature, humidity may be within the range of suitability for lifecycle of the pest.
