Abstract

Entomopathogenic fungi have significant potential to control mosquito population. The culture filtrates of Fusarium oxysporum, Lagenidium giganteum, Trichophyton ajelloi, and Culicinomyces clavisporus were evaluated against adults of Cx. quinquefasciatus. The culture filtrates were obtained by filtering the broth through Whatman-1 filter paper. These culture filtrates of C. clavisporus have been found significantly pathogenic with LC50-2.5, LC90-7.24, and LC99-8.7 ML, respectively, after exposure of 24 h. However, the culture filtrates when were combined, in ratios 1 : 1 : 1 of Fusarium oxysporum, Lagenidium giganteum, Trichophyton ajelloi the mortalities were significantly increased. The LC50-3.71, LC90-8.12, and LC99-11.48 were significantly recorded after exposure of 10 hrs. Similarly, the culture filtrates of T. ajelloi, Culicinomyces clavisporus, and L. giganteum have been combined in ratios 1 : 1 : 1. Similarly the LC50-1.94, LC90-4, and LC99-6.16 ML Were recorded after exposure of 10 hrs. The results of present study show promise for the use of selected fungal metabolites for control of Cx. quinquefasciatus in the Laboratory.
