Evaluation of botanicals against: Mosquito Larvae to the Extracts of Fungus Beauveria Species

The larvicidal activity of Beauveria species on mosquito Culex quiquefaciatus, Armegeries subalbatus and Anopheles species was done, penicilliumis a large genus of filamentous fungi widely distributed in soil and in associated with plants. It was observed that more toxicity of Beauveria extract towards the larvae of Anopheles species than Culex quinquifaciatus, The toxicity was lesser in Aremgeries subalbatus, The toxicity range was observed between 100 ppm to 250 ppm. The toxicity on mosquito may be due to the toxins, and secondary metabolites of Beauveria species. Cyanide also creates toxicity on larvae, Beauveria based mosquito control can be done after field trials under controlled environment.
