Fall armyworm, shortly abbreviated as FAW, is a serious insect pest that causes significant yield losses in maize. The purpose of this study was to find out how different planting dates influence the incidence of FAW during kharif 2021 and rabi 2021-22. A total of six plantings have been taken up, and the maize hybrid DHM 117 was sown at fortnightly intervals. At varied planting dates, the percent plant infestation, larval population, and fecundity of fall armyworm were correlated with weather variables. The FAW infestation and larval population were negatively impacted by rainfall, relative humidity i.e, RH-I & RH-II, and minimum temperature, while maximum temperature exhibited a positive association. However, egg-laying was negatively influenced by every weather parameter studied. Thus, understanding the role of weather variables in FAW incidence is essential in developing forewarning models and sustainable management strategies.
