No-till agriculture, combined with the practices of continuous soil cover by retaining crop residues and of crop rotation, including cover crops, represents a relatively widely adopted management system that aims to increase soil organic matter content as well as long-term sustainability. However, its impacts on wireworm populations in the soil and risk of damage to crops are uncertain, and current recommendations may unjustifiably limit grower options. Consequently, this study examined the effects of no-tillage soil management on the population dynamics of Agriotes wireworm pests (Coleoptera: Elateridae) by bait sampling, maize plant damage assessments, and pheromone trapping (adults) within three farms in northeastern Italy, from 2011 through 2016, as compared to conventional tillage. The four-year cropping rotation consisted of winter wheat (Triticum aestivum), oilseed rape (Brassica napus), maize (Zea mays), and soybean (Glycine max) under both tillage treatments. The nature and intensity of damage caused by wireworms to maize early stages was assessed each year. Wireworms and beetles comprised of four different species (A. brevis, A. sordidus, A. ustulatus, and A. litigiosus) were captured, with the numerically dominant species (A. sordidus) accounting for over 90% of all captures. All species responded similarly to tillage practices. No effects of tillage operations were associated with beetle captures (P > 0.28) and larval densities (P > 0.45). No differences were observed between tillage treatments in wireworm feeding maize damage scores (P > 0.17; means for no-till and conventional tillage maize were 3.82 and 4.14 percent damage, respectively). These results suggest that switching from a conventional tillage system to a no-till maize production may not cause an increase of wireworm damage to maize, even though no-till conditions have been historically associated with increased wireworm damage risk. Possible causes of these results are discussed.

免耕农业与通过保留作物残留物和轮作作物（包括覆盖作物）进行连续土壤覆盖的做法相结合，代表了一种相对广泛采用的管理系统，旨在增加土壤有机质含量和长期可持续性。然而，它对土壤中线虫种群的影响和对作物的损害风险尚不确定，目前的建议可能会不合理地限制种植者的选择。因此，本研究考察了免耕土壤管理对Agriotes种群动态的影响。从 2011 年到 2016 年，与传统耕作相比，意大利东北部三个农场通过诱饵采样、玉米植物损害评估和信息素诱捕（成虫）对线虫害虫（鞘翅目：线虫科）进行了调查。在两种耕作处理下，四年轮作包括冬小麦（Triticum aestivum）、油菜（Brassica napus）、玉米（Zea mays）和大豆（Glycine max）。每年都会评估线虫对玉米早期造成的损害的性质和强度。线虫和甲虫由四种不同的物种（A. brevis、A. sordidus、A. ustulatus和A. litigiosus 组成）) 被捕获，数量上占优势的物种 ( A. sordidus ) 占所有捕获量的 90% 以上。所有物种对耕作方式的反应都相似。耕作操作的影响与甲虫捕获（P  > 0.28）和幼虫密度（P  > 0.45）无关。不同耕作处理在线虫饲喂玉米损伤评分上无差异（P > 0.17；免耕和常规耕作玉米的平均值分别为 3.82% 和 4.14%）。这些结果表明，从传统耕作系统转向免耕玉米生产可能不会导致线虫对玉米的损害增加，即使免耕条件历来与线虫损害风险增加有关。讨论了这些结果的可能原因。
