The plight of insects has generated worldwide attention from the scientific community and wider public. Recent interest was stimulated by a 27 year study1 suggesting a loss of 75% in the biomass of flying insects from Protected Areas in Germany, quickly labelled as 'ecological Armageddon'. If replicated in other habitats and regions, the scale of this loss is likely to have major implications for the role of insects in ecosystem functioning (e.g. pollination, pest control, nutrient cycling and as a food resource for other species). There is a need to understand the linkages between the status of insect populations and human-driven environmental changes, such as climate change and habitat degradation, and their impact on the resilience of ecosystem functions and services which underpin human well-being.

昆虫的困境引起了科学界和广大公众的广泛关注。最近的一项为期27年的研究激发了人们的兴趣，该研究表明德国保护区的飞虫生物量损失了75%，很快被称为“生态末日”。如果在其他生境和地区复制，这种损失的规模可能会对昆虫在生态系统功能中的作用产生重大影响（例如授粉、虫害控制、营养循环和作为其他物种的食物资源）。有必要了解昆虫种群状况与气候变化和生境退化等人为环境变化之间的联系，及其对支撑人类福祉的生态系统功能和服务的复原力的影响。
