一个假设是建议，昆虫物种的数量与树是一个累积丰富的树在一个特定的地区在整个最近的地质历史（如在第四纪）的反映。这意味着占主导地位的树木将拥有最多的昆虫物种，而最近引入的昆虫物种最少。在英国、瑞典、俄罗斯和塞浦路斯的某些树木上发现的昆虫之间进行了一般性的比较，这些都支持了这一假设。对英国进行了更详细的测试，结果表明，与英国树木有关的主要食草昆虫目的物种数量与其第四纪遗迹的记录数量密切相关。当消除累积丰度的影响时，发现少数树木似乎特别抵抗昆虫定植，而其他树木则可能相反。
An hypothesis is suggested that the number of insect species associated with a tree is a reflection of the cumulative abundance of that tree in a particular area throughout recent geological history (e.g. in the Quaternary period). This means that dominant trees will have most insect species and recently introduced ones the fewest. General comparisons are made between insects found on certain trees in Britain, Sweden, Russia and Cyprus, and these support the hypothesis. A more detailed test is made for Britain, where it is shown that the number of species of major plant-feeding orders of insects associated with British trees is closely correlated with the number of records of their Quaternary remains. When the effect of cumulative abundance is eliminated it is found that a few trees appear to be especially resistant to insect colonization, and others probably the reverse.
