Four isolates of Beauveria bassiana were tested against two age groups i.e. 0-24 hr and six day old larvae of Spodoptera litura by direct topical methods and crawling on treated leaves to observe the effect on growth and development. Six concentrations of each isolate were used against both the age groups and both the methods of application. Larval and pupal periods of neonate and 6 day old larvae were not affected by all isolates. However, percent pupation and adult emergence were significantly decreased in all isolates of B. bassiana at 106 to 108 spores per ml when applied on neonate larvae while low percent pupation and adult emergence were recorded only at 108 spores per ml when applied by both the methods.
