一个长期存在的假说声称，植物饲养昆虫专门对特定的宿主植物，因为负面的相互作用（权衡）之间的适应替代主机，但经验证据这种权衡是稀缺的。大多数研究都在寻找昆虫物种内部的微进化性能权衡，但宿主使用也可能受到上位性和历史偶然性引起的宏观进化权衡的限制。另一方面，对不同宿主的适应之间的进化相互作用可能是中性的或积极的，而不是消极的。在这里，我们使用了系统发育的方法来估计的微观和宏观进化之间的相关性使用的替代寄主植物内两个主要订单的植物饲养昆虫：鳞翅目（毛虫）和半翅目（真正的错误）。在1604毛毛虫物种，我们发现使用不同的主机类群之间的正相关和负相关，与整体网络模式表明，不同的主机使用的限制作用在微观和宏观进化的时间尺度。与此相反，主机使用模式的955个真正的错误物种揭示了均匀的正相关性存在于同一主机类群在两个时间尺度。跨时间尺度和昆虫订单缺乏一致的模式表明，主机使用的权衡是历史上偶然的，而不是普遍的限制。此外，我们观察到一些负相关的整体，尽管广泛的分类和生态多样性的焦点主机类群，这表明主机使用的适应，而不是权衡之间的积极相互作用，占主导地位的长期演变的主机使用植食性昆虫。
A long-standing hypothesis asserts that plant-feeding insects specialize on particular host plants because of negative interactions (trade-offs) between adaptations to alternative hosts, yet empirical evidence for such trade-offs is scarce. Most studies have looked for microevolutionary performance trade-offs within insect species, but host-use could also be constrained by macroevolutionary trade-offs caused by epistasis and historical contingency. On the other hand, evolutionary interactions between adaptations to diverse hosts could be neutral or positive rather than negative. Here we used a phylogenetic approach to estimate the micro-and macroevolutionary correlations between use of alternative host plants within two major orders of plant-feeding insects: Lepidoptera (caterpillars) and Hemiptera (true bugs). Across 1604 caterpillar species, we found both positive and negative pairwise correlations between use of diverse host taxa, with overall network patterns suggesting that different host-use constraints act over micro-and macroevolutionary timescales. In contrast, host-use patterns of 955 true bug species revealed uniformly positive correlations between presence on the same host taxa over both timescales. The lack of consistent patterns across timescales and insect orders indicates that host-use trade-offs are historically contingent rather than universal constraints. Moreover, we observed few negative correlations overall despite the wide taxonomic and ecological diversity of the focal host taxa, suggesting that positive interactions between host-use adaptations, not trade-offs, dominate the long-term evolution of host use in plant-feeding insects.
