Outline of Final Research Achievements |
Control researches of Anopheles by entomopathogenic fingi have evaluated only virulence, however in this study, we focussed on sub-lethal effect including host seeking behavior, blood sucking behavior, ovipositional behavior. As a result, in host seeking behavior, fungus infected mosquito was less able to detect heat, color, and odor. In blood sucking behavior, the amount and rate of blood sucking were decreased by fungal infection. In ovipositional behavior, follicle development was surpressed and the number of oviposition and hatching rate were decreased. Inhibition of these behaviors will directry affect to efficiency of infectious diseases transmission. It shows that it is possible to generate inactivated vector in epidemiological sense by infection of entomopathogenic fungi.
