The introduction of alien species is one of the main problems in conservation. Many successful invaders cause severe economic and ecological damage. Such is the case of Leptoglossus occidentalis, a phytophagous true bug native to North America, which has become a pest in Europe, Asia, Africa and South America. Within the genus, another species whose distributional range is expanding toward the east of North America is Leptoglossus clypealis. As climate determines the successful establishment of insects, the identification of climatically suitable areas for invasive species based on ecological niche models (ENMs) offers an excellent opportunity for preventing invasions. In this study, ENMs were built for both species and their native climatic niches were compared. Their niche breath was also measured. The climatic niches of both species are identical and the niche breadth of L. clypealis is broader than that of L. occidentalis. In view of the great ecological resemblance between these two species, we believe that L. clypealis could became a major pest thus it should be carefully monitored. The results of the present worldwide ENMs showed numerous regions with suitable conditions for the establishment of both species. The future ENMs exhibited a retraction in the suitable areas in North America, Europe and Asia.

Leptoglossus clypealis 的生态位模型 (ENM) 是一种新的潜在全球入侵者:跟随 Leptoglossus occidentalis 的脚步?

引进外来物种是保护的主要问题之一。许多成功的入侵者造成了严重的经济和生态破坏。情况就是这样西洋舌鱼,一种原产于北美的植食性真虫,已成为欧洲、亚洲、非洲和南美洲的害虫。在该属内,另一个分布范围正在向北美东部扩展的物种是绦虫. 由于气候决定了昆虫的成功建立,因此基于生态位模型(ENM)确定适合入侵物种的气候区域为防止入侵提供了绝佳的机会。在这项研究中,为这两个物种建立了 ENM,并比较了它们的原生气候生态位。他们的利基气息也被测量了。两个物种的气候生态位相同,生态位宽度L. lypealisL. occidentalis. 鉴于这两个物种之间的巨大生态相似性,我们认为L. lypealis可能成为主要害虫,因此应仔细监测。目前全球 ENMs 的结果表明,许多地区具有适合建立这两个物种的条件。未来的 ENM 在北美、欧洲和亚洲的合适地区表现出退缩。
