Invasions of a number of tree-feeding beetles have increased globally and pose a mounting threat to the world's trees, production forests and natural habitats. An in-depth understanding of the determinants of invasion potential of a given species and invasibility of novel environments can help forecast future invasions and avert undesirable socio-economic impacts. Here, we quantitatively assess the (multivariate) drivers of historic invasions of the coconut hispid Brontispa longissima (Coleoptera: Chrysomelidae) across the Asia-Pacific region and critically assess its invasion potential for other key coconut-growing regions.
Genetic variation of B. longissima in its invaded range indicated multiple incursions, likely associated with (short-range) natural dispersal and (long-range) trade in ornamental palms and coconut plantlets. Interception records at China's ports of entry accentuate the role of traded planting material. The high fecundity and prolonged, yet adaptable, oviposition period of B. longissima further enhance the invasiveness of this species and aid its successful establishment. Coconut-growing areas are identified with high climatic suitability for B. longissima, and where strengthened biosecurity protocols can prevent future invasions.
A combined assessment of inter-country trade patterns, population genetics and species bio-ecology (e.g. climate-related development) illuminates the dispersal pathways of invasive species, assesses invasibility of particular geographies, guides quarantine interventions and thus can effectively avert future invasions. © 2019 Society of Chemical Industry.
大量的食树甲虫入侵在全球范围内不断增加，对世界上的树木、人工林和自然栖息地构成了越来越大的威胁。深入了解特定物种的入侵潜力和新环境的可入侵性，可以帮助预测未来的入侵，并避免产生不良的社会经济影响。在这里，我们定量评估了椰子鳞皮潜叶甲（鞘翅目：叶甲科）在亚太地区的历史入侵的（多变量）驱动因素，并批判性地评估了其对其他关键椰子种植地区的入侵潜力。
在其入侵范围内的 B. longissima 的遗传变异表明存在多次入侵，可能与（短距离）自然扩散和（长距离）贸易中的观赏棕榈和椰子幼苗有关。在中国入境口岸的截获记录强调了贸易种植材料的作用。B. longissima 的高繁殖力和延长但适应性强的产卵期进一步增强了该物种的入侵性，并有助于其成功建立。椰子种植地区具有高度适合 B. longissima 的气候条件，加强生物安全协议可以防止未来的入侵。
对国家间贸易模式、种群遗传学和物种生物生态学（例如与气候相关的发展）的综合评估揭示了入侵物种的传播途径，评估了特定地理区域的可入侵性，指导了检疫干预措施，从而可以有效地避免未来的入侵。© 2019 化学工业协会。
