Spodopterafrugiperda(J.E.Smith),秋季粘虫(一汽),多食夜蛾害虫,于2016年在乌干达首次报道。农民接受了识别和管理害虫的培训,但是缺乏关于农民知识的信息,为控制它而部署的观念和实践。因此,我们进行了一项调查,以评估玉米农民的知识,入侵期间害虫的感知和管理。我们使用结构良好的问卷采访了乌干达10个种植玉米的农业生态区(AEZ)的1,289个玉米农民。使用R版本4.2.3分析数据。受访者面临许多限制,包括害虫,干旱,贫瘠的土壤和劳动力的限制。在害虫中,大多数受访者(85%)将一汽列为玉米头号害虫问题,一些农民报告说早在2014年就注意到了这一点。到2018年,90%以上的农民看过或听说过一汽,大约80%的人在他们的领域看到了一汽。玉米种植者报告的最常见的一汽症状是开窗,隧道附近的损坏,和玉米棒上的洞。农民确定的一汽发育阶段包括鸡蛋(10%),幼体(78.7%),成熟幼虫(73.5%)和成蛾(6.7%)。杀虫剂是主要的控制策略,尽管一些农民使用植物提取物,手工采摘,沙子,还有灰.农民从各种来源获取有关一汽的信息,包括农民同胞们,收音机/电视,扩展代理,输入经销商,打印介质,研究和非政府组织推广。有必要为农民打包清晰统一的信息,并制定和推广一汽管理的可持续解决方案,包括利用生物控制和文化习俗。
Spodoptera frugiperda (J.E. Smith), fall armyworm (FAW), a polyphagous Noctuid pest, was first reported in Uganda in 2016. Farmers were trained to identify and manage the pest, but there was a lack of information on farmer knowledge, perceptions and practices deployed to control it. Therefore, we conducted a survey to assess maize farmers\' knowledge, perceptions and management of the pest during the invasion. We interviewed 1,289 maize farmers from 10 maize-growing agro-ecological zones (AEZ) of Uganda using well-structured questionnaires. The data were analyzed using R version 4.2.3. The respondents faced many constraints, including pests, drought, poor soils and labor constraints. Among the pests, FAW was ranked by most (85%) of the respondents as the number one pest problem in maize, and some farmers reported having noticed it way back in 2014. By 2018, more than 90% of the farmers had seen or heard about FAW, and about 80% saw FAW in their fields. The most common FAW symptoms reported by maize farmers were windowing, near tunnel damage, and holes on the cobs. The developmental stages of FAW identified by farmers included eggs (10%), young larvae (78.7%), mature larvae (73.5%) and adult moths (6.7%). Insecticides were the major control tactic, although some farmers used plant extracts, hand-picking, sand, and ash. Farmers sourced information on FAW from various sources, including fellow farmers, radio/TV, extension agents, input dealers, print media, research and NGO extension. There is a need to package clear and uniform information for the farmers and to develop and promote a sustainable solution for FAW management, including harnessing biological control and cultural practices.
