摘要
【背景】水果害虫铃木氏果蝇近年来传入许多国家,成为重要的入侵害虫,在我国的危害也呈现上升趋势。在水果生产中,铃木氏果蝇常与其他果蝇混合发生。【方法】在对我国水果产区果蝇进行系统调查的基础上,对分别采自山东威海、云南昆明、山东淄博、山东临沂地区的铃木氏果蝇、黑腹果蝇、海德氏果蝇、伊米果蝇的形态特征进行了比较,并利用线粒体COⅠ基因对所鉴别的果蝇物种进行了进一步验证。【结果】通过观察比较种间雄虫前翅和前足以及雌虫腹部和产卵器形态结构可以快速确定果蝇种类。【结论与意义】本研究认为,在宁德地区,互花米草在7月前侧重分蘖生长,7月后根茎开始快速生长,此结论为优化互花米草防治适期提供了参考。
[ Background ] The fruit pest Drosophila suzukii Matsumura has been introduced into many countries in recent years and has become a major invasive species. D. suzukii has been becoming more and more serious in China during the past several years as well. In fruit production, D. suzukii often co-occurs with other fruit fly species. [ Method ] The morphological characteristics of the adult D. suzukii, D. melanogaster, D. hydei and D. immigrans, which were collected from Weihai of Shandong, Kunming of Yunnan, Zibo of Shandong, and Linyi of Shandong, respectively, were compared. The mitochondrial cytochrome oxidase I （mtCOI） gene of the four fruit flies were used to further determine the species. [ Result] Drosophila species can be determined quickly according to the morphological characteristics of the male forewings, male forefeet, female abdomen, and female ovipositor. [ Conclusion and significance]The study shows that S. alterniflora mainly focuses on tiller growth before July, and start to grow quickly after July in Ningde area, which provides a theoretical reference for control of S. alterniflora.
