Use of mycelial suspension and metabolites of Paecilomyces lilacinus (Fungi: Hyphomycetes) in control of Aedes aegypti larvae.

ABSTRACT

Mycelial suspension of possible was assessed to examine its Paecilomyces lilanicus, a fungus, detrimental effects on fourth instar larvae of Aedes aegypti. The immature stages suffered 64-68% mortality with 0.5-1% mycelial suspension. There was 12-16% adult emergence which was statistically significant (P < 001). Czapeckdox and PYG media metabolites were used against the third instar larvae in various concentrations. The effects were evaluated on several parameters like mortality, mean survival time and time taken for adult emergence. The results indicate that the fungus does not producae any toxic metabolites.
