Insect conservation is often impeded by a lack of species-specific data leading to difficulties in assessment of conservation and threat status. Utilising specimens and records held within natural history museums may help to overcome such limitations. We used specimens and their associated data from the New Zealand Arthropod Collection to provide a comparative analysis of threatened species and their related non-threatened congeners. A range of insect groups were covered, including families from the five mega-diverse insect orders. Data on the locality, date, habitat, and morphological measurements, were recorded for nearly 25,000 specimens from 460 species, of which 31 are Threatened and 104 are At Risk. Results found the Protected Area Network provided significantly less coverage for insect species classified as Threatened or At Risk. Body size, geographical distribution, and environmental variables were not consistent predictors of the current threat classification system. There were a disproportionately large number of At Risk species found on offshore islands. The current New Zealand threat classification system, based on trends in geographical occurrence and population sizes, does not accurately reflect the conservation needs of most insect species. This has significant implications for the utility of threat assessments for insect conservation.

利用博物馆数据对受威胁昆虫物种进行比较分析

昆虫保护往往因缺乏特定物种数据而受到阻碍,从而导致难以评估保护和威胁状况。利用自然历史博物馆内保存的标本和记录可能有助于克服这些限制。我们使用来自新西兰节肢动物收藏的标本及其相关数据,对受威胁物种及其相关的非受威胁同源物进行了比较分析。涵盖了一系列昆虫群,包括来自五个超级多样化昆虫目的科。记录了来自 460 个物种的近 25,000 个标本的地点、日期、栖息地和形态测量数据,其中 31 个受到威胁,104 个处于危险之中。结果发现保护区网络对被列为受威胁或处于危险中的昆虫物种提供的覆盖范围要小得多。身体尺寸,地理分布和环境变量并不是当前威胁分类系统的一致预测指标。在离岸岛屿上发现了大量不成比例的处于危险中的物种。当前的新西兰威胁分类系统基于地理发生和种群规模的趋势,并不能准确反映大多数昆虫物种的保护需求。这对昆虫保护威胁评估的效用具有重要意义。不能准确反映大多数昆虫物种的保护需求。这对昆虫保护威胁评估的效用具有重要意义。不能准确反映大多数昆虫物种的保护需求。这对昆虫保护威胁评估的效用具有重要意义。
