杨十斑吉丁虫(Melanophila decastigma Fabr.)病原真菌虽有一些记载,但尚未做寄主致病性测定及野外防治该虫的试验,1987—1989年我们在甘肃省酒泉市三合林场、敦煌县南河乡林场和阳关林场杨十斑吉丁虫发生地被害杨树(二白杨、小叶杨等)内剖到感病死亡的虫体,并调查统计了野外自然发病情况。经室内分离培养和致病性测定以及野外应用防治杨十斑吉丁虫幼虫
Although there are some records about pathogenic fungi of Melanophila decastigma Fabr, we did not test the host pathogenicity and test the field in the field. From 1987 to 1989, we studied in Sanhe Forest Farm, Jiuquan, Gansu Province, County Nanhe Township Forest Farm and Yang Guan Lin Yang Burson-& lt; / RTI & gt; spotted poplar (Populus tomentosa, Populus tomentosae, etc.) dissected to dead insects, and surveyed the natural incidence of the wild. After indoor culture and pathogenicity determination and field application prevention and control Yang ten spotted bugs larvae
