Abstract

Investigation on seasonal incidence of fall army worm Spodoptera frugiperda on maize was undertaken at the Department of Entomology, VNMKV, Parbhani. The studies were done during kharif on the maize variety Komal. Laval incidence was observed from 31st SMW (Standard Meteorological Week) i.e. fifth week of July and to till 43rd SMW i.e. fourth week of October with a peak incidence observed (4.05 larvae/plant) during 39th SMW. Thereafter larval count showed declining trend (1.9 larvae/plant) during 42nd SMW. Larval infestation also recorded in %age and under observation highest infestation 38.98% during 39th SMW i.e. fourth week of September. The correlation between larval incidence and weather parameters was showed negatively non-significant with minimum temperature, evening relative humidity and rainfall, whereas positive relationship was observed with maximum temperature and bright sunshine hours. The correlation with morning relative humidity evaporation with FAW population wee positively and negativity significant respectively evaporation was negative significant.
