Abstract

Seasonal incidence of fall army worm in maize at Dharwad indicated its occurrence both in and kharifrabi seasons The incidence was more during the season. Highest incidence of 50% was noticed during last . kharif week of August and second peak incidence of 30% was noticed during last week of December. Correlation between seasonal incidence of fall army worm and weather parameters indicated that there was a significant negative correlation with the rainfall (-0.60**) and morning humidity (-0.50*). Biology of fall army worm indicated that it completed its total life cycle in 31-44 days on maize comprising of six larval instar stages. Among the entomo-pathogens tested against the fall army worm,(2 x 10 cfu/g)Metarhizium (Nomuraea) rileyi 8 was found to be superior and it was at par with neem formulation (azadirachtin 3000 ppm) @ 5ml/l
