Corn, Zea mays L. (Cyperales: Poaceae), production is essential to Iowa’s economy and provides food, feed, and fuel beyond the state. Farmers face a number of challenges in corn production, including insect pests, and understanding farmers’ perceptions and concerns is critical for extension personnel to provide adequate and relevant programming. The Iowa State University Agriculture and Natural Resources Crops Team conducted a survey of Iowa farmers and agribusiness professionals during the 2019–2020 extension season. The goal was to understand farmer perceptions of corn pests and whether farmers experienced challenges with resistance to Bt traits or insecticides. Additionally, we aimed to realize farmers’ confidence in developing resistance management plans and discussing those needs with their input suppliers and advisors. Our survey revealed that northern corn rootworm, Diabrotica barberi Smith & Lawrence (Coleoptera: Chrysomelidae), was the pest of greatest concern across the state. People were generally more concerned about belowground Bt trait performance than aboveground traits, though only 12% of respondents reported Bt trait failure for corn rootworms. In general, people were not concerned about the performance of seed treatments or soil- or foliar-applied insecticides. Farmers generally felt very confident in developing a resistance management plan and discussing their needs with their advisors. The results of this survey will be used to target extension programming throughout the state and increase confidence for farmers and agribusiness employees to discuss resistance management plans together.

爱荷华州玉米害虫管理的需求评估

玉米,Zea mays L.(Cyperales:禾本科),生产对爱荷华州的经济至关重要,并为州外提供食物、饲料和燃料。农民在玉米生产中面临着许多挑战,包括害虫,了解农民的看法和担忧对于推广人员提供适当和相关的计划至关重要。爱荷华州立大学农业和自然资源作物小组在 2019-2020 年延长季节对爱荷华州农民和农业综合企业专业人士进行了调查。目的是了解农民对玉米害虫的看法,以及农民是否遇到了对 Bt 性状或杀虫剂抗性的挑战。此外,我们旨在增强农民对制定抗性管理计划的信心,并与他们的投入供应商和顾问讨论这些需求。我们的调查显示,北方玉米根虫 Diabrotica barberi Smith & Lawrence(鞘翅目:菊科)是全州最受关注的害虫。人们普遍更关心地下 Bt 性状的表现,而不是地上性状,尽管只有 12% 的受访者报告玉米根虫的 Bt 性状失败。一般来说,人们并不关心种子处理或土壤或叶面施用杀虫剂的性能。农民普遍对制定抗性管理计划并与顾问讨论他们的需求充满信心。该调查的结果将用于针对全州的扩展计划,并增强农民和农业综合企业员工共同讨论抗药性管理计划的信心。劳伦斯(鞘翅目:菊科)是全州最受关注的害虫。人们普遍更关心地下 Bt 性状的表现,而不是地上性状,尽管只有 12% 的受访者报告玉米根虫的 Bt 性状失败。一般来说,人们并不关心种子处理或土壤或叶面施用杀虫剂的性能。农民普遍对制定抗性管理计划并与顾问讨论他们的需求充满信心。该调查的结果将用于针对全州的扩展计划,并增强农民和农业综合企业员工共同讨论抗药性管理计划的信心。劳伦斯(鞘翅目:菊科)是全州最受关注的害虫。人们普遍更关心地下 Bt 性状的表现,而不是地上性状,尽管只有 12% 的受访者报告玉米根虫的 Bt 性状失败。一般来说,人们并不关心种子处理或土壤或叶面施用杀虫剂的性能。农民普遍对制定抗性管理计划并与顾问讨论他们的需求充满信心。该调查的结果将用于针对全州的扩展计划,并增强农民和农业综合企业员工共同讨论抗药性管理计划的信心。人们普遍更关心地下 Bt 性状的表现,而不是地上性状,尽管只有 12% 的受访者报告玉米根虫的 Bt 性状失败。一般来说,人们并不关心种子处理或土壤或叶面施用杀虫剂的性能。农民普遍对制定抗性管理计划并与顾问讨论他们的需求充满信心。该调查的结果将用于针对全州的扩展计划,并增强农民和农业综合企业员工共同讨论抗药性管理计划的信心。人们普遍更关心地下 Bt 性状的表现,而不是地上性状,尽管只有 12% 的受访者报告玉米根虫的 Bt 性状失败。一般来说,人们并不关心种子处理或土壤或叶面施用杀虫剂的性能。农民普遍对制定抗性管理计划并与顾问讨论他们的需求充满信心。该调查的结果将用于针对全州的扩展计划,并增强农民和农业综合企业员工共同讨论抗药性管理计划的信心。人们并不关心种子处理或土壤或叶面施用杀虫剂的性能。农民普遍对制定抗性管理计划并与顾问讨论他们的需求充满信心。该调查的结果将用于针对全州的扩展计划,并增强农民和农业综合企业员工共同讨论抗药性管理计划的信心。人们并不关心种子处理或土壤或叶面施用杀虫剂的性能。农民普遍对制定抗性管理计划并与顾问讨论他们的需求充满信心。该调查的结果将用于针对全州的扩展计划,并增强农民和农业综合企业员工共同讨论抗药性管理计划的信心。
