昆虫数量的时间趋势因研究和栖息地而异，但驱动因素知之甚少。合适的长期数据很少，而且存在偏见，对趋势的解释仍然存在争议。相比之下，空间变化的驱动因素有大量的量化证据。通过观察和实验研究，我们对昆虫丰度和多样性较高的地方有了深刻的了解，并确定了潜在的环境条件、资源变化和干扰。因此，我们建议在研究昆虫减少的原因时增加对空间证据的考虑。这是因为对于目前可用的大多数时间序列，站点的数量和统计能力大大超过了研究的年份数。不同地点的比较可以量化昆虫种群风险、土地使用的影响、栖息地破坏、恢复或管理，以及化学和光污染、农药、割草或收割、极端气候或生物入侵等压力因素。值得注意的是，驱动因素可能不必改变强度就能对人口产生长期影响，例如每年重复的干扰或农业做法引起的死亡风险。空间换时间的问题一直存在争议。然而，来自复制良好的空间数据的证据可以为制止或扭转下降所需的紧急行动提供信息-在太空中实施。
Temporal trends in insect numbers vary across studies and habitats, but drivers are poorly understood. Suitable long-term data are scant and biased, and interpretations of trends remain controversial. By contrast, there is substantial quantitative evidence for drivers of spatial variation. From observational and experimental studies, we have gained a profound understanding of where insect abundance and diversity is higher—and identified underlying environmental conditions, resource change and disturbances. We thus propose an increased consideration of spatial evidence in studying the causes of insect decline. This is because for most time series available today, the number of sites and thus statistical power strongly exceed the number of years studied. Comparisons across sites allow quantifying insect population risks, impacts of land use, habitat destruction, restoration or management, and stressors such as chemical and light pollution, pesticides, mowing or harvesting, climatic extremes or biological invasions. Notably, drivers may not have to change in intensity to have long-term effects on populations, e.g. annually repeated disturbances or mortality risks such as those arising from agricultural practices. Space-for-time substitution has been controversially debated. However, evidence from well-replicated spatial data can inform on urgent actions required to halt or reverse declines—to be implemented in space.
