is a perennial shrub native to Southeast Asia and is invasive in South Florida and Hawai'i, USA. During surveys of in Hong Kong from 2013-2018 for potential biological control agents, we collected larvae of the stem borer, . Larvae were shipped in stems to a USDA-ARS quarantine facility where they were reared and subjected to biology studies and preliminary host range examinations. is the most recent species to be described from males collected in Vietnam and Indonesia. Because the original species description was based on only two male specimens, we also provide a detailed description of the female, egg, larva, and pupa. Finally, we conducted preliminary host range trials utilizing , , and . emerged from a Florida-native shrub, and larvae were able to survive in non-target stems for over a year (>400 days). Based on these findings and difficulty in rearing, we do not believe is a suitable insect for biological control of at this time, but may warrant further study. This investigation also illustrates the importance of host surveys for conservation and taxonomic purposes.
是一种原产于东南亚的多年生灌木，在美国南佛罗里达州和夏威夷是入侵物种。在2013年至2018年对香港进行的潜在生物防治剂调查中，我们采集了蛀茎螟的幼虫。幼虫被装在茎中运往美国农业部农业研究局的检疫设施，在那里饲养并进行生物学研究和初步寄主范围检查。是从在越南和印度尼西亚采集的雄性个体中描述的最新物种。由于最初的物种描述仅基于两个雄性标本，我们还提供了雌性、卵、幼虫和蛹的详细描述。最后，我们利用、和进行了初步寄主范围试验。从一种佛罗里达州本土灌木中羽化，幼虫能够在非目标茎中存活一年多（超过400天）。基于这些发现以及饲养困难，我们认为目前不是用于生物防治的合适昆虫，但可能值得进一步研究。这项调查也说明了寄主调查对于保护和分类目的的重要性。
