| 摘 要： | 草地贪夜蛾(Spodoptera frugiperda)是一种洲际迁飞性农业害虫,食谱广泛. 2019年5月已迁飞至重庆地区,对农作物造成严重危害.为了解入侵重庆地区草地贪夜蛾(Spodoptera frugiperda)肠道真菌菌群的组成,本研究以采集自重庆巫山玉米田及重庆江津高粱田中的草地贪夜蛾幼虫为材料,运用传统培养方法分离其粪便中的肠道优势真菌,并对其进行形态学观察和分子生物学鉴定.实验通过分离培养不同地区、不同食物的草地贪夜蛾肠道真菌,结合形态学观察及rDNA ITS测序完成了属水平的鉴定,共分离得到了5个属10个真菌分离株,其中分离自重庆巫山玉米田的草地贪夜蛾肠道真菌归为3个属,分别为念珠菌属(Candida)、掷孢酵母属(Sporobolomyces)和帚枝霉属(Sarocladium);分离自重庆江津高粱田的草地贪夜蛾肠道真菌归为3个属,分别为念珠菌属(Candida)、莫氏黑粉菌属(Moesziomyces)和毛霉属(Mucor).初步分离获得入侵重庆地区的草地贪夜蛾肠道真菌,丰富了对入侵草地贪夜蛾肠道微生物的认识.

| Abstract: | Spodoptera frugiperda is a migratory agricultural pest with a wide range of recipes. It migrated to Chongqing in May of 2019, causing serious damages to crops. In order to explore the structural composition of the intestinal fungal flora of S. frugiperda larvae in Chongqing, we used the larvae of S. frugiperda collected from the corn field in Wushan and the sorghum field in Jiangjin. The dominant intestinal fungi in the feces were isolated by traditional culture method and identified with morphological observation and ITS sequencing. In the experiments, ten fungal isolates were obtained and classified into five genera. The intestinal fungi isolated from the larvae in the Wushan corn field were classified into three genera, Candida, Sporobolomyces and Sarocladium. The intestinal fungi isolated from S. frugiperda of the Jiangjin sorghum field were classified into three genera, Candida, Moesziomyces and Mucor. This experiment initially isolated the intestinal fungi of S. frugiperda, thus enriching our understanding of the intestinal microbes of this pest. |
