Data underlying the publication: Arthropod predator identity and evenness jointly shape delivery of pest control services

Maximising the effectiveness of natural pest control requires a detailed understanding of how service delivery is affected by natural enemy community diversity and composition. Many studies have investigated the effects of natural enemy abundance and species richness on pest control. Studies examining the effects of evenness and species identity are fewer and have produced inconsistent results. Here we test the effects of arthropod predator community evenness and species identity on natural pest control by exposing aphid (<em>Sitobion avenae</em>) colonies in experimental cages to arthropod predator communities that had the same abundance and species richness but that differed in evenness and dominant species.

若要最大化自然害虫防控（natural pest control）的效能，需深入明晰天敌群落（natural enemy community）的多样性与组成如何调控害虫防控服务的实施效果。既往已有大量研究探讨了天敌种群丰度与物种丰富度对害虫防控的影响效应。但针对群落均匀度与物种特性（species identity）的研究相对较少，且所得结果并不一致。本研究通过将实验笼内的麦长管蚜（*Sitobion avenae*）种群暴露于种群丰度与物种丰富度一致，但群落均匀度和优势物种存在差异的节肢动物捕食者群落中，以此检验节肢动物捕食者群落的均匀度与物种特性对自然害虫防控的影响。
