Data from: Honeydew associated with four common crop aphid species increases longevity of the parasitoid wasp, Bracon cephi (Hymenoptera: Braconidae)

Data are from a laboratory experiment conducted to examine the potential effects of honeydew from six different aphid species by crop species combinations on the longevity of Bracon cephi Gahan (Hymenoptera: Braconidae), the most important biological control of the wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), a major pest of wheat in the northern Great Plains of North America. We quantified the number of days parasitoids lived on each honeydew type.
Abstract from published manuscript:
The absence of sugar resources can be an important factor in limiting the success of parasitoids as biological control agents. Restoring vegetation complexity within agricultural landscapes has thus become a major focus of conservation biological control efforts, with a traditional emphasis on nectar resources. Aphid honeydew is also an important source of sugars that is infrequently considered. We carried out a laboratory experiment to examine the potential effects of honeydew from six different aphid species by crop species combinations on the longevity of Bracon cephi Gahan (Hymenoptera: Braconidae), the most important biological control of the wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), a major pest of wheat in the northern Great Plains of North America. The benefits of honeydew for parasitoid longevity varied significantly among different aphid and crop species, illustrating the complexity of these interactions. However, honeydew produced by four aphid species commonly found in wheat, pea, and canola crops significantly increased the longevity (by two- to threefold) of the parasitoid. The study suggests that honeydew provisioning could be an important mechanism underlying the benefits of crop diversification to support biological control that merits further research.

本研究数据来源于一项旨在探究六种不同蚜虫种类分泌的蜜露对小麦茎麦秆蝇（Hymenoptera: Braconidae）重要生物防治物种 Bracon cephi Gahan 生存寿命影响的实验室实验。小麦茎麦秆蝇，即 Cephus cinctus Norton（Hymenoptera: Cephidae），是北美北部大平原地区小麦的主要害虫。本研究量化了寄生蜂在不同蜜露类型上的存活天数。摘要来自已发表的手稿：糖资源的缺失可能是限制寄生蜂作为生物防治剂的成效的重要因素。因此，在农业景观中恢复植被复杂性已成为保护生物防治努力的重点，传统上这一努力集中于花蜜资源的恢复。蚜虫蜜露也是糖的重要来源，但其重要性往往被忽视。本研究通过实验室实验，考察了六种不同蚜虫种类分泌的蜜露通过作物种类组合对小麦茎麦秆蝇重要生物防治物种 Bracon cephi Gahan 生存寿命的影响。不同蚜虫和作物种类产生的蜜露对寄生蜂寿命的影响存在显著差异，揭示了这些交互作用的复杂性。然而，在小麦、豌豆和大豆作物中常见的四种蚜虫分泌的蜜露显著增加了寄生蜂的寿命（增加两至三倍）。该研究提出，蜜露的供应可能是作物多样化支持生物防治成效的重要机制，值得进一步研究。本数据集中包含以下资源：
