昆虫的减少及其驱动因素最近引起了相当大的关注。萤火虫和萤火虫是标志性的昆虫，它们引人注目的生物发光求偶展示具有独特的文化意义，使它们具有生态旅游景点的经济价值。尽管有证据表明萤火虫数量下降，但缺乏对全球约2000种萤火虫物种的保护状况和面临的威胁的全面审查。我们对来自不同地理区域的专家进行了一项调查，以确定萤火虫种群和物种持久性的最突出的威胁。栖息地丧失、光污染和农药使用被认为是最严重的威胁，尽管各地区的排名差异很大。我们的调查结果伴随着全面审查目前的证据，这些压力对萤火虫种群的影响。我们还讨论了可能增加某些物种对特定威胁的脆弱性的风险因素。最后，我们强调有必要建立监测计划，以跟踪长期人口趋势的风险萤火虫类群。
Insect declines and their drivers have attracted considerable recent attention. Fireflies and glowworms are iconic insects whose conspicuous bioluminescent courtship displays carry unique cultural significance, giving them economic value as ecotourist attractions. Despite evidence of declines, a comprehensive review of the conservation status and threats facing the approximately 2000 firefly species worldwide is lacking. We conducted a survey of experts from diverse geographic regions to identify the most prominent perceived threats to firefly population and species persistence. Habitat loss, light pollution, and pesticide use were regarded as the most serious threats, although rankings differed substantially across regions. Our survey results accompany a comprehensive review of current evidence concerning the impact of these stressors on firefly populations. We also discuss risk factors likely to increase the vulnerability of certain species to particular threats. Finally, we highlight the need to establish monitoring programs to track long-term population trends for at-risk firefly taxa.
