Abstract

Objective

To isolate the entomopathogenic fungus Metarhizium anisopliae (M. anisopliae) in the local environment, and evaluate its efficacy against the suspected dengue vector Aedes albopictus in Pakistan.

Methods

According to the standard procedure, M. anisopliae was isolated from the dead mosquitoes which were collected from the field or dead after the collection. Bioassay was performed to determine its efficacy.

Results

The results indicated that M. anisopliae had larvicidal effect with LC50 value 1.09×105 and LC90 value 1.90×1013 while it took 45.41 h to kill 50% of tested population.

Conclusions

Taking long time to kill 50% population when compare with the synthetic insecticides, is the only drawback for the use of entomopathogenic fungus but these bio-pesticides are safe for the use.
