Abstract

Cover crops (CC) support populations of pest and beneficial arthropods. The status of these arthropods in the subsequent cash crop depends on several factors such as CC species, management, biomass production, and weather conditions. A systematic review was performed to identify how CC management influences pest and beneficial arthropods and to identify knowledge gaps for the future research efforts. Eight studies included in this review indicated that CC increase beneficial arthropods or some beneficial arthropods compared with the CC managed fields. A minority of the studies indicated an increase in pest presence when using CC. Cover crop species, termination time and methods, and CC management had variable responses on arthropod activity-density. The variable responses, differences on study designs, and complexity of CC management influence arthropod activity in a CC-corn [Zea mays L. (Poaceae)]/soybean [Glycine max L. (Fabaceae)] system, limiting our ability to draw a broad and effective conclusion about the CC management impact on arthropods. Local research studies are needed to identify the impact of CC biomass quality and quantity, CC biomass thresholds for pest and beneficial arthropods, and cash crop yield impact of CC management-arthropod-related studies. Studies using the standard farming practices of each U.S. region and using standard measurements are needed to guide farmers that use cover crops. This systematic review aims to provide a better understanding of how the complexity of management in cover crop-corn/soybean management affects arthropod activity-density and to identify potential gaps in research and address future research needs.

覆盖作物管理是否会影响美国随后的玉米和大豆作物中的节肢动物？系统评价

抽象的

覆盖作物（CC）支持害虫和有益节肢动物的种群。这些节肢动物在随后的经济作物中的地位取决于几个因素，例如CC种类，管理，生物量生产和天气状况。进行了系统的审查，以确定CC管理如何影响害虫和有益的节肢动物，并确定知识缺口以用于未来的研究工作。这篇综述中的八项研究表明，与CC管理的领域相比，CC增加了有益的节肢动物或某些有益的节肢动物。少数研究表明，使用CC时害虫的存在增加。覆盖的作物种类，终止时间和方法，以及CC处理对节肢动物活动密度的反应各不相同。反应不一，研究设计的差异，管理的复杂性和复杂性影响CC-玉米[Zea mays L.（Poaceae）] /大豆[Glycine max L.（Fabaceae）]系统中节肢动物的活动，从而限制了我们就CC管理影响得出广泛而有效的结论的能力。在节肢动物上。需要进行地方研究来确定CC生物量质量和数量的影响，有害生物和有益节肢动物的CC生物量阈值以及CC管理-节肢动物相关研究对经济作物产量的影响。需要进行研究，使用美国每个地区的标准耕作方法并使用标准测量方法，以指导使用遮盖作物的农民。
