Abstract

Forty-six water and soil samples were collected from various larval mosquito habitats of four districts of Madhya Pradesh for isolation of fungal pathogens against Aedes aegypti. Five fungal isolates, namely, Beauveria bassiana, B. nivea, Myrothecium roridum, Aspergillus flavus and Trichoderma harzianum, were found to have potential against the third instar larvae. Larvae of A. aegypti were found to be more susceptible to B. nivea (LD50 value of 1.2í—105 conidia ml−1). M. roridum yielded lowest LC50 value (67.61 µl ml−1) of extracellular metabolite, which was followed by A. flavus (107.15µl ml−1). Highest LC50 value (631.0µl ml−1) was obtained for T. harzianum. In case of M. roridum, larval mortality occurred due to toxic metabolites present in the sporodochia.
