The sunn pests (Eurygaster spp.) which are important pests of wheat and barley, can lead to 100% yield loss in the case of an epidemic. This study was conducted to characterize the entomopathogenic fungi, obtained from the sunn pests collected from different overwintering areas of Turkey and determine their pathogenicity. Seventeen Beauveria pseudobassiana, 12 Beauveria bassiana, 16 Cordyceps farinosa, 1 Purpureocillium lilacinum, and 2 Clonostachys rosea species were identified. Pathogenicity tests were performed with three B. pseudobassiana, two B. bassiana, four C. farinosa, and one P. lilacinum isolates. B. pseudobassiana isolates BB34 and AF4 caused 100% death on the 9th day, and another B. pseudobassiana isolate E512 caused 100% death on the 12th day. C. farinosa isolate KOKA2 caused 95.8% death on the 15th day. Ultimately, B. pseudobassiana was determined to be the most prevalent and virulent species on sunn pests.

来自土耳其害虫的昆虫病原真菌的特征和毒力

wheat虫(Eurygaster spp。)是小麦和大麦的重要害虫,在流行时会导致100%的产量损失。进行这项研究的目的是鉴定昆虫病原真菌的特征,该真菌是从土耳其不同的越冬地区收集的晒黑害虫中获得的,并确定了它们的致病性。鉴定了17种白僵菌,12种白僵菌,16种冬虫夏草,1种紫紫线虫和2种玫瑰梭菌。致病性测试是对3个拟假单胞菌,两个B. bassiana,4个C. farinosa和1个进行的。体育紫丁香分离物。B. pseudobassiana隔离BB34和AF4造成100%死亡的第9天,和另一个B. pseudobassiana分离E512造成100%死亡的第12天。C. farinosa分离KOKA2导致在15日95.8%的死亡。最终,假单胞菌被确定为在sun害虫上最普遍和最有毒力的物种。
