Larvicidal efficiency of the mushroom Amanita muscaria (Agaricales, Amanitaceae) against the mosquito Culex quinquefasciatus (Diptera, culicidae)

Abstract

Introduction: We report the larvicidal activity of two formulations from Amanita muscaria against Culex quinquefasciatus, as well as the viability of the aqueous extract after storage. Methods: The larvicidal activity of aqueous extract and powder from A. muscaria, and the viability of the aqueous extract after storage, were evaluated. Results: The aqueous extract caused larval deaths, which varied from 16.4% to 88.4%. The efficiency of the powder varied from 29.2% to 82.8%. Storage did not interfere with the larvicidal efficiency of the aqueous extract of A. muscaria. Conclusions: These results show the potential of A. muscaria to control C. quinquefasciatus.
