摘要: 以稻水象甲为靶虫,对37株不同来源的绿僵菌菌株进行了致病性检测,结果有6株致病率大于90 %。对不同生育期的稻水象甲感病性测定表明,在寄主产卵期感病性最强,越冬期次之,新羽化代最低。在成虫产卵期施用绿僵菌,对控制稻水象甲有明显的作用。

Abstract: Pathogenicity of 37 isolates of Metarhizium anisopliae to Lissorhoptrus oryzophilus and the sensitivity of L.oryzophilus at different stages to M.anisopliae were tested. The results showed that 6 isolates of M.anisopliae parasitized over 90% of L.oryzophilus. L.oryzophilus was more sensitive to the infection of M.anisopliae at the reproductive stage, and mediate at the over wintering stage and less sensitive at the emerge stage.
