Abstract

The Asian longhorned beetle (ALB), Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), is a destructive invasive woodboring insect pest, and efforts are being made to find parasitoids for ALB biological control. Through a four-year survey in Korea using a sentinel log trap associated with host chemical cues potentially important for host finding by parasitoids, two parasitoid species were discovered attacking ALB. One species is Spathius ibarakius Belokobylskij & Maetô, which is known to also parasitize citrus longhorned beetle, Anoplophora chinensis (Forster). The other parasitoid species, whose offspring were dead before imago, could not be morphologically identified at the adult stage. We attempted molecular and morphological identification of the larvae/pupae of the unidentified parasitoid; however, only superfamily-level identification was possible. The parasitism rate recovered in the logs was 0.3% by the unidentified parasitoid in Gapyeong-gun in 2019, while it reached 29.2% by S. ibarakius in Busan city in 2022. Future efforts for exploring ALB natural enemies in the pest’s native range may focus on parasitoids with high parasitism rates.

利用改进的定点原木诱捕器在韩国寻找亚洲长角金龟寄生虫

亚洲长角甲虫(Anoplophora glabripennis (Motschulsky))(鞘翅目:天牛科)是一种具有破坏性的木材入侵害虫，寻找拟寄生物对其进行生物防治已成为研究热点。通过在韩国进行的为期四年的调查，使用与寄主化学线索相关的哨兵日志陷阱，发现两种寄主物种攻击ALB。其中一种是Spathius ibarakius Belokobylskij & Maetô，已知它也寄生于柑橘长角甲虫，anplophora chinensis (Forster)。其他拟寄生物的后代在成虫期就已死亡，在成虫期不能进行形态鉴定。对未鉴定的寄生蜂幼虫/蛹进行了分子和形态鉴定;然而，只有超家族水平的识别是可能的。2019年在加平郡发现的未查明寄生蜂在原木上的寄生率为0.3%，而2022年在釜山市发现的寄生蜂的寄生率为29.2%。今后对白蛉天敌的探索，可将重点放在寄生率较高的拟寄生蜂上。

期刊介绍： Parasite is an international open-access, peer-reviewed, online journal publishing high quality papers on all aspects of human and animal parasitology. Reviews, articles and short notes may be submitted. Fields include, but are not limited to: general, medical and veterinary parasitology; morphology, including ultrastructure; parasite systematics, including entomology, acarology, helminthology and protistology, and molecular analyses; molecular biology and biochemistry; immunology of parasitic diseases; host-parasite relationships; ecology and life history of parasites; epidemiology; therapeutics; new diagnostic tools. All papers in Parasite are published in English. Manuscripts should have a broad interest and must not have been published or submitted elsewhere. No limit is imposed on the length of manuscripts, but they should be concisely written. Papers of limited interest such as case reports, epidemiological studies in punctual areas, isolated new geographical records, and systematic descriptions of single species will generally not be accepted, but might be considered if the authors succeed in demonstrating their interest.
