Database of the list for associations between host plants and fruit flies

Insects tend to feed on related hosts. Coevolution tends to be dominated by interactions resulting from plant chemistry in defense strategies, and evolution of secondary metabolisms being in response to insect herbivory remains a classic explanation of coevolution. The present study examines whether evolutionary constraints existing in host associations of economically important fruit flies in the species-rich tribe Dacini (Diptera: Tephritidae) and to what extent these species have evolved specialized dietary patterns. We found a strong effect of host phylogeny on associations on the 37 fruit flies tested, although the fruit fly species feeding on ripe commercially grown fruits that lost the toxic compounds after long domestication are mostly polyphagous. We assessed the phylogenetic signal of host breadth across the fruit fly species, showing that the results were substantially different depending on partition levels. Further, we mapped main host family associations onto the fruit fly...昆虫通常取食亲缘关系相近的寄主（host）。协同进化（coevolution）往往由植物防御策略中的化学相互作用主导，而针对昆虫植食性演化次生代谢（secondary metabolism）的过程，仍是阐释协同进化的经典理论。本研究旨在探究物种丰富的寡鬃实蝇族（Dacini，双翅目：实蝇科）内具有重要经济价值的实蝇，其寄主关联是否存在演化限制，以及这些物种在多大程度上演化出特化的食性模式。我们对37种受试实蝇的分析显示，寄主系统发育（phylogeny）对其寄主关联具有显著影响；不过以经过长期驯化后丧失有毒成分的成熟商业化栽培果实为食的实蝇物种，大多属于多食性（polyphagous）类群。我们还评估了各实蝇物种寄主广度（host breadth）的系统发育信号（phylogenetic signal），结果表明，依据系统发育划分层级（partition levels）的不同，分析结果存在显著差异。此外，我们将主要寄主科的关联关系映射至实蝇……
