Objective:To isolate the entomopathogenic fungus Metarhixium 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 LC,value 1.09×10~5 and LC_(50) value 1.90×10~(13) 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.

Methods: According to the standard procedure, M. isisopliae 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 LC, value 1.09 × 10 ~ 5 and LC_ (50) value 1.90 × 10 ~ (13) 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.
