摘要

许多褐飞虱是重要的经济作物和广泛种植的作物(如水稻、玉米和甘蔗)的主要害虫。在它们自然迁移或新引入的地区,这些昆虫有可能成为严重的农作物害虫。白腹飞虱,Stenocranus pacificus Kirkaldy, 1907,原产于热带南太平洋岛屿,于21世纪初出现在热带和亚热带亚洲。从那时起,太平洋葡萄球菌已经成为一些东南亚国家玉米的严重害虫,尽管它也以水稻、甘蔗、高粱和其他禾草为食。在此,我们报告了在日本大陆存在的S. pacificus,这是该物种在温带亚洲的首次记录。根据2019年和2020年在熊本县采集的7只雄性和17只雌性成年个体的形态特征和线粒体COI序列,鉴定为太平洋S. pacificus。此外,分子系统发育分析表明,S. pacificus与其他狭爪属形成了一个不同的分支,表明其属归属的不确定性。尽管温带地区尚未报告太平洋S. pacificus对作物的危害,但鉴于其广泛的寄主范围和未来范围扩大的潜力,应监测亚洲(包括温带地区)受损作物的存在。

First report of the invasive crop pest Stenocranus pacificus (Hemiptera: Delphacidae) in temperate Asia

First report of the invasive crop pest Stenocranus pacificus (Hemiptera: Delphacidae) in temperate Asia

Numerous delphacid planthopper species are major pests of economically important and widely cultivated crops (i.e. rice, corn, and sugarcane). These insects have the potential to become serious crop pests in areas where they have either naturally migrated or been newly introduced. The white-bellied planthopper, Stenocranus pacificus Kirkaldy, 1907, originally known from tropical South Pacific islands, appeared in tropical and subtropical Asia in the early years of the 21st century. Since then, Spacificus has become a serious pest of corn in some Southeast Asian countries, although it also feeds on rice, sugarcane, sorghum, and other grasses. Here, we report the presence of Spacificus in mainland Japan, representing the first record of this species in temperate Asia. Seven male and 17 female adult individuals collected in Kumamoto Prefecture in 2019 and 2020 were identified as Spacificus based on their morphological characteristics and mitochondrial COI sequences. In addition, molecular phylogenetic analysis showed that Spacificus formed a distinct clade from other Stenocranus species, indicating uncertainty in its generic assignment. Although crop damage by Spacificus has not yet been reported from temperate regions, given its wide range of plant hosts and the potential for future range expansions, damaged crops in Asia, including in temperate regions, should be monitored for the presence of this species.

期刊介绍: Entomological Science is the official English language journal of the Entomological Society of Japan. The Journal publishes original research papers and reviews from any entomological discipline or from directly allied field in ecology, behavioral biology, physiology, biochemistry, development, genetics, systematics, morphology, evolution and general entomology. Papers of applied entomology will be considered for publication if they significantly advance in the field of entomological science in the opinion of the Editors and Editorial Board.
