Delphacid planthoppers (Hemiptera: Delphacidae) are a group of economically important sap-feeding insects that vector plant pathogens and are pests of crops, such as maize, wheat, and rice. This study was conducted to evaluate planthopper diversity, abundance, and the presence of potential vectors on maize crops and associated edge grass habitats. In Jalisco, west-central Mexico, delphacids were sampled using a sweep net in two different habitats (with and without irrigation) during the dry and rainy seasons of 2013 and 2014. A total of 5,621 specimens were collected and nine species were identified: Metadelphax propinqua (Fieber), Delphacodes koebelei Muir and Giffard, Delphacodes arcuata Beamer, Sogatella kolophon (Kirkaldy), Syndelphax fulvidorsum (Metcalf), Chionomus balboae (Muir & Giffard), Toya idonea (Beamer), Syndelphax humilis (Van Duzee), and Tagosodes cubanus (Crawford) (Hemiptera: Delphacidae), all belonging to the tribe Delphacini (Delphacinae). A high diversity of delphacids was found in the edge grasses during the dry season and rainy season. Planthopper abundance was higher in the edge grasses than in the maize fields during the rainy season. The most abundant species was M. propinqua representing 67.5% of the specimens collected. Populations of M. propinqua in edge grasses peaked during the dry season in December and January. Metadelphax propinqua, S. kolophon, and T. cubanus are known to be potential plant pathogen vectors.

墨西哥玉米作物和边缘草上飞虱（半翅目：飞虱科）的多样性

Delphacid 飞虱（半翅目：Delphacidae）是一组具有重要经济意义的以汁液为食的昆虫，它们是植物病原体的载体，是玉米、小麦和水稻等作物的害虫。本研究旨在评估飞虱的多样性、丰度以及玉米作物和相关边缘草生境中潜在载体的存在。在墨西哥中西部的哈利斯科州，在 2013 年和 2014 年的旱季和雨季期间，在两个不同的栖息地（有灌溉和没有灌溉）中使用扫网对飞蚊进行了采样。总共收集了 5,621 个标本，并确定了九个物种： Metadelphax propinqua (Fieber), Delphacodes koebelei Muir and Giffard, Delphacodes arcuata Beamer, Sogatella kolophon (Kirkaldy), Syndelphax fulvidorsum (Metcalf), Chionomus balboae (Muir & Giffard), Toya idonea (Beamer), Syndelphax humilis（Van Duzee）和Tagosodes cubanus（Crawford）（半翅目：Delphacidae），都属于Delphacinae（Delphacinae）部落。在旱季和雨季的边缘草中发现了高度多样性的飞燕草。在雨季，边缘草中的飞虱丰度高于玉米地。最丰富的物种是 M. propinqua，占收集到的标本的 67.5%。M. propinqua 在边缘草中的数量在 12 月和 1 月的旱季达到顶峰。Metadelphax propinqua、S. kolophon 和 T. cubanus 已知是潜在的植物病原体载体。在雨季，边缘草中的飞虱丰度高于玉米地。最丰富的物种是 M. propinqua，占收集到的标本的 67.5%。M. propinqua 在边缘草中的数量在 12 月和 1 月的旱季达到顶峰。Metadelphax propinqua、S. kolophon 和 T. cubanus 已知是潜在的植物病原体载体。在雨季，边缘草中的飞虱丰度高于玉米地。最丰富的物种是 M. propinqua，占收集到的标本的 67.5%。M. propinqua 在边缘草中的数量在 12 月和 1 月的旱季达到顶峰。Metadelphax propinqua、S. kolophon 和 T. cubanus 已知是潜在的植物病原体载体。
