On account of chitinolytic nature of certain keratinophilic fungi, bioefficacy of Chrysosporium evolceanui spore suspension was tested against Anopheles stephensi and Culex quinquefasciatus larvae. The median lethal concentration of the spore suspension of the fungus was observed as 9.0 x 103 sp/ml and 5.6 x 103 sp/ml after 24 and 48 hours of exposure, respectively, against culicine larvae. The spores invaded the head region of the larvae, however, the entry restricted in thorax and abdominal region. It was found more effective in the case of anopheline larvae with LC50 1.4 x 103 sp/ml after 24 hours and 1.1 x 103 after 48 hours of treatment.
