Abstract

We report the establishment of the invasive eucalyptus weevil Gonipterus platensis in the high elevation Nilgiri Plateau in the state of Tamil Nadu, India. Its presence was first brought to light by observations uploaded on iNaturalist, a citizen science platform, from Eucalyptus globulus plantations. Specimens collected from the plantations were examined morphologically and dissected to reveal the diagnostic characters of G. platensis. DNA sequences of the cytochrome c oxidase gene (COI) amplified from Indian specimens were 0.3% different from G. platensis sequences from Tasmanian populations and over 4% different from any other Gonipterus species for which DNA data are available. Sequence data from 6 invasive populations of G. platensis indicates multiple, independent invasions from a Tasmanian source population to different parts of the world. The collection of specimens, including larvae, over multiple years indicates that the population in the Nilgiris is persistent, with the earliest evidence for its presence in the region being March 2019. We recommend further monitoring and assessment of population growth and spread of Gonipterus platensis to minimize the economic impact of this potentially important pest of Eucalyptus in India. Citizen science played a critical role in this discovery, and we recommend that subject experts engage with nature enthusiasts on platforms like iNaturalist so that the wide reach of public participation is harnessed to effectively monitor biodiversity.

在印度泰米尔纳德邦建立了非本地桉树象鼻虫Gonipterus platensis(鞘翅目:树象鼻虫科)。
本文报道了在印度泰米尔纳德邦高海拔尼尔吉里高原建立的入侵桉树象鼻虫高原Gonipterus platensis。它的存在最初是由公民科学平台iNaturalist上传到桉树种植园的观察结果引起的。对各人工林标本进行了形态学检查和解剖,以揭示其诊断特征。从印度标本中扩增的细胞色素c氧化酶基因(COI)序列与塔斯马尼亚种群的G. platensis序列差异0.3%,与任何其他可获得DNA数据的Gonipterus物种的DNA序列差异超过4%。6个platensis入侵种群的序列数据表明,platensis从塔斯马尼亚源种群向世界不同地区进行了多次独立入侵。多年来收集的标本(包括幼虫)表明,Nilgiris的种群是持久的,其在该地区存在的最早证据是在2019年3月。我们建议进一步监测和评估platipterus的种群增长和传播,以尽量减少这种潜在的重要害虫对印度桉树的经济影响。公民科学在这一发现中发挥了关键作用,我们建议学科专家在像iNaturalist这样的平台上与自然爱好者接触,这样就可以利用广泛的公众参与来有效地监测生物多样性。

期刊介绍: The Journal of Insect Science was founded with support from the University of Arizona library in 2001 by Dr. Henry Hagedorn, who served as editor-in-chief until his death in January 2014. The Entomological Society of America was very pleased to add the Journal of Insect Science to its publishing portfolio in 2014. The fully open access journal publishes papers in all aspects of the biology of insects and other arthropods from the molecular to the ecological, and their agricultural and medical impact.
