Abstract:
The present study attempts to analyze the virulence of Beauveria bassiana on Culex pipiens pallens from different habitats, such as sewage at Tangkou Town hospital ( A) , polluted piggery water at the outskirts of Jining City ( B) , drainage ditch of paddy field in Weishan Lake ( C) , vats in Shandong Institute of Parasitic Diseases ( D) and laboratory ( E) , and to provide a theoretical basis for biological control of mosquitoes.Spore suspension of B.bassiana was used to process the larvae of Cx.pipiens pallens collected from different habitats.The dead number of larvae was recorded and the median lethal time ( LT50 ) was calculated.The larval mortality was more than 95%10 d after treatment by B.bassiana.The LT50 values of A, B, C, D and E were 6.2 d, 6.4 d, 5.7 d, 5.8 d and 3.8 d, respectively.The LT50 of larvae reared in laboratory was lower.Under laboratory conditions, B.bassiana showed efficient control effect on Cx.pipiens pallens collected from different habitats.The peak value of dead larvae reared in laboratory was 2-3 days in advance than those collected outdoors.It is expected to use B.bassiana in the biological control of mosquitoes.
