Abstract

The studies on seasonal incidence of Fall armyworm (FAW) Spodoptera frugiperda (J.E. Smith) on Maize in India was carried out at Maize research centre Rajendranagar, Hyderabad, during Rabi 2022-23. The correlation studies revealed that the percent infestation of FAW was found to be negatively significant with maximum temperatures (-0.491*) and positively significant with morning relative humidity (0.565*). Correlation of natural enemies (coccinellids, spiders, earwigs) with weather parameters (Maximum temperature, Minimum temperature, Relative humidity during morning and evening) revealed that coccinellids, spiders and earwigs were found to be positively significant with maximum temperature and spiders found to be negatively significant with evening relative humidity. They were found to be non-significant with remaining parameters.
