Abstract
Globally, maize is known as âQueen of cerealsâ because of its highest genetic yield potential and has many types including yellow, white, popcorn, baby corn, sweet, coloured, waxy, protein-rich and high-oil. A field experiment was conducted to record the seasonal activity of S. frugiperda in maize during Rabi season. The infestation of fall armyworm started in the 4th week of November (47th SMW) with a mean population of 0.87 larvae per ten plants and mean plant damage with 28.3 per cent per ten plants. The infestation of fall armyworm was reached to its maximum with 1.20 larvae per ten plants and plant damage of 38.7 per cent was observed in fourth week of December (52th SMW). The adult of fall armyworm catches in trap were reached to its maximum adult population of 9.0 in first week of December (49th SMW). Mean larval and adult population showed that the non-significant correlation with weather parameters. Whereas, plant damage per cent had significant negative with maximum temperature and sunshine hours.
