摘　　要：近年来,褐梗天牛(Arhopalus rusticus)野外种群优势不断加大,已严重威胁我国森林生态安全,对褐梗天牛的防治已刻不容缓。本文通过一系列试验筛选得到对褐梗天牛有杀灭效果的层生镰刀菌(Fusarium proliferatum)CS-03,该菌株72 h发酵液处理褐梗天牛3 d的累计校正死亡率达86.7%,此发现为首次。同时,通过林间药效试验,发现经层生镰刀菌CS-03500倍稀释发酵液处理后,该区域平均虫口减退率在70%以上;说明层生镰刀菌CS-03能够有效防治褐梗天牛发生与扩散,在褐梗天牛的生物防治中具有广泛的应用前景。In recent years,the population dominance of Arhopalus rusticus in the wild has been increasing,which has seriously threatened the forest ecological security in China.Therefore,it is urgent to prevent and control the brown terrierArhopalus rusticus.In this paper,Fusarium proliferatum CS-03,which is effective in killing Arhopalus rusticus,is identified through a series of tests.The accumulative corrected mortality of Arhopalus rusticusafter 72 h fermentation solution treatment is 86.7%,which is the first discovery.At the same time,through the forest efficacy test,it was found that the average pest reduction rate in the area was more than 70%after the fermentation broth was diluted 500 times by the layer Fusarium proliferatum CS-03.These results indicate that Fusarium proliferatum CS-03 can effectively control the occurrence and spread of Arhopalus rusticus brown terrier,and has a wide application prospect in the biological control of Arhopalus rusticus brown terrier.
