摘要
葛粉虫(Megacopta cribraria (F.) (Heteroptera: Plataspidae))原产于亚洲,2009 年首次在美国佐治亚州被发现,此后被认为是大豆(Glycine max (L.) Merrill; Fabales:豆科)的害虫。Megacopta cribraria 在 2009 年至 2013 年期间迅速扩散,之后扩散速度急剧下降。尽管出现了下降,但已建立的种群仍保持稳定。这一下降可能部分归因于野葛蝽的天敌。例如,自 2016 年和 2013 年以来,美国偶尔会发现外来卵寄生虫 Ooencyrtus nezarae Ishii(膜翅目:Encyrtidae)和 Paratelenomus saccharalis (Dodd)(膜翅目:Platygastridae)。我们从野葛(Pueraria montana Lour.(Merrill) var. lobata (Willd.))中发现了 O. nezarae。尽管有人根据葛虫卵的出孔来推测 O. nezarae 出现在佐治亚州南部,但据我们所知,本报告是首次记录并确认 O. nezarae 在田纳西州和佐治亚州的葛虫卵中的恢复情况。此外,在 2017 年采集时,这次恢复也是北美首次确认从葛藤中发现该物种。这种早季天敌与晚期出现的昆虫病原体 Beauveria bassiana (Balsamo-Crivelli) Vuillemin 相结合,可能会降低并维持葛粉虱的密度,从而减轻对大豆生产者的经济影响。
Ecological Insights and First Confirmed Record of Ooencyrtus nezarae (Hymenoptera: Encyrtidae) on Eggs of Megacopta cribraria (Hemiptera: Plataspidae) in Tennessee and Georgia1
The kudzu bug, Megacopta cribraria (F.) (Heteroptera: Plataspidae), is native to Asia, was first detected in Georgia, USA, in 2009, and has since been recognized as a damaging pest of soybean (Glycine max (L.) Merrill; Fabales: Fabaceae) in several southeastern states. Megacopta cribraria dispersed rapidly from 2009 to 2013, after which its spread rate declined sharply. Despite this decline, established populations have remained stable. This decline may be partially attributed to natural enemies of kudzu bug. For example, the exotic egg parasitoids Ooencyrtus nezarae Ishii (Hymenoptera: Encyrtidae) and Paratelenomus saccharalis (Dodd) (Hymenoptera: Platygastridae) have been occasionally detected in the United States since 2016 and 2013, respectively. We recovered O. nezarae from M. cribraria eggs collected from wild patches of kudzu (Pueraria montana Lour. (Merrill) var. lobata (Willd.)) throughout summer 2017. Although the occurrence of O. nezarae in southern Georgia has been suggested based on exit holes from kudzu bug eggs, to our knowledge, this report is the first to document and confirm recovery of O. nezarae from kudzu bug eggs in both Tennessee and Georgia. In addition, at the time of collection in 2017, this recovery was the first confirmation of this species from kudzu in North America. This early-season natural enemy combined with the later-occurring entomopathogen Beauveria bassiana (Balsamo-Crivelli) Vuillemin may reduce and maintain kudzu bug densities, which could lessen economic impacts on soybean producers.
