Effect of entomopathogenic fungus, <i>Beauveria bassiana </i>on larvae of three species of mosquitoes

Abstract

<i>Beauveria bassiana, </i>an entomopathogenic fungus, was evaluated for its potenti al against second and third instar larvae of <i>Culex quinquefasciatus, Anopheles stephensi </i>and <i>Aedes aegypti. </i>Conidiospores of this fungus were effective in causing infection leading to mortality of different larval instars. Larvae of <i>Cx. quinquefasciatus </i>were more susceptible to infection than <i>An. stephensi </i>and the second instar larvae of these two species were more susceptible than third in star larvae. Larvae of <i>Ae. aegypti </i>were resistant to infection by <i>B. bassiana.</i>
