| Abstract: | Micromelalopha troglodyta is an important leaf-eating pest of poplar in Dongting Lake area.There are 7 generations per year.In this paper,the control test on the 1st and 2nd instar of the first and second generations of M.troglodyta by releasing Beauveria bassiana in May or June was conducted.The results showed that,pathologic reaction of M.troglodyta appeared on the 4th d after releasing B.bassiana,M.troglodyta started to die 5d later,the peak of death emerged on the 7th d,and reached 55.4% of mortality rate on the 10th d.By means of natural disperse of spores or infection of larva feed,B.bassiana made a strong inhibitory effect on the population of M.troglodyta of following generations. |
