- 摘要:
- 选择2种虫生真菌对白星花金龟幼虫的室内致病力进行了测定。结果表明:累计校正死亡率Ma3最高,为80.8%,Ma1、Ma2、5SO3分别为68.4%、38.7%、32.5%;各处理在0.05和0.01水平上均呈极显著差异;僵虫率5SO3最高,为45.5%,Ma3、Ma1、Ma2分别为42.3%、37.5%、28.2%,各处理之间差异极显著。Ma1和Ma3的LT50较短为5 d,5 SO3和Ma2的LT50分别为6和8 d。
- Abstract:
- In this thesis,the virulence of two kinds of fungus to Potosia brevitarsis Lewis larva were detected.The results showed that adjust accumulative mortality rates of Ma3 was the highest,reached 80.8%,Ma1,Ma2,5SO3 were 68.4%,38.7%,32.5%,respectively;Cadaver rates of 5SO3 was the highest,reached 45.5%,Ma3,Ma1,Ma2 reached 42.3%,37.5%,28.2% respectively,LT50 of Ma1 and Ma2 were five days,5 SO3 and Ma2 were 6 days and 8 days.
