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.
