A preliminary study was conducted to evaluate the effects of nine methanol fungal
extracts on fourth instar larvae of Aedes caspius and Culex pipiens (Diptera:
Culicidae). None of the extracts tested showed larvicidal activity except for the
Paecilomyces lilacinus extract, which showed 100 % mortality against the larvae
of Ae caspius after 24 h. The LC50 values of the P. lilacinus extract after 24 h were
190.66 μg/mL against Ae. caspius and 254.25 μg/mL against Cx. pipiens,
