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5d,5SO3和Ma2的LT50分别为6和8d。
In this thesis, the virulence of two kinds of fungus to Potosia brevitar.sis 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, Mal, 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.
