环境压力的存在加速了农药暴露释放的抗性种群的遗传恢复。相比之下，环境压力的相关性，在农药暴露的耐药性的传播还没有研究。此外，不同的压力之间的相互作用的后果没有被考虑。在这里，我们表明，通过种内竞争的压力加速微进化，因为它增强了适应和非适应个体之间的适应性差异。相比之下，通过种间竞争或捕食的压力减少种内竞争，从而延迟微进化。这在接触杀虫剂毒死蜱的蚊子种群（致倦库蚊）中得到了证明。通过收获和与大型蚤的种间竞争进行的非选择性捕食推迟了对携带ace-1 R抗性等位基因的个体的选择。在无毒条件下，没有ace-1 R的易感个体占主导地位。同样，捕食延缓了种群对无毒环境的反向适应，而种间竞争的影响不显著。应用模拟模型，我们进一步确定了微进化通常是如何由竞争和捕食的类型和程度决定的。我们推断，与其他物种的相互作用，特别是在具有高生物多样性的生态系统中，可以延缓杀虫剂抗性的发展。
The genetic recovery of resistant populations released from pesticide exposure is accelerated by the presence of environmental stressors. By contrast, the relevance of environmental stressors for the spread of resistance during pesticide exposure has not been studied. Moreover, the consequences of interactions between different stressors have not been considered. Here we show that stress through intraspecific competition accelerates microevolution, because it enhances fitness differences between adapted and non-adapted individuals. By contrast, stress through interspecific competition or predation reduces intraspecific competition and thereby delays microevolution. This was demonstrated in mosquito populations (Culex quinquefasciatus) that were exposed to the pesticide chlorpyrifos. Non-selective predation through harvesting and interspecific competition with Daphnia magna delayed the selection for individuals carrying the ace-1R resistance allele. Under non-toxic conditions, susceptible individuals without ace-1R prevailed. Likewise, predation delayed the reverse adaptation of the populations to a non-toxic environment, while the effect of interspecific competition was not significant. Applying a simulation model, we further identified how microevolution is generally determined by the type and degree of competition and predation. We infer that interactions with other species—especially strong in ecosystems with high biodiversity—can delay the development of pesticide resistance.
