本文首次报道了埃塞俄比亚和肯尼亚农民对秋粘虫的认识、看法和管理措施。对343个玉米小农户进行了调查。埃塞俄比亚和肯尼亚的大多数农民都了解秋粘虫;他们主要在幼虫阶段就能识别它。此外，埃塞俄比亚（93%）和肯尼亚（97%）的大多数农民在其农场中遇到了秋粘虫的损害。他们估计，埃塞俄比亚平均有32%的作物受损，肯尼亚平均有47.3%的作物受损，估计产量减少0.8至1吨/公顷。近一半的农民依靠化学杀虫剂来控制这种害虫。肯尼亚的大多数农民（60%）认为杀虫剂对控制秋粘虫无效，而埃塞俄比亚的大多数农民（46%）认为化学喷雾对控制秋粘虫有效。在埃塞俄比亚，26%的农民将手工采摘幼虫与杀虫剂喷雾相结合，而15%的农民只进行手工采摘。本研究强调需要根据农民的需要和优先事项制定秋粘虫管理战略。
This paper reports for the first time on farmers' knowledge, perceptions and management practices of the fall armyworm (Spodoptera frugiperda) in Ethiopia and Kenya. A survey of 343 smallholder maize farmers was conducted. Most farmers in Ethiopia and Kenya had knowledge about fall armyworm; they could identify it mainly during its larval stage. Furthermore, most farmers in Ethiopia (93%) and Kenya (97%) encountered damage by fall armyworm in their farms. They estimated an average of 32% crop damage in Ethiopia and 47.3% of crop damage in Kenya, with an estimated yield reduction between 0.8 to 1 tonnes/ha. Nearly half of the farmers relied on chemical insecticides to control this pest. The majority (60%) of the farmers in Kenya perceived that insecticides were not effective in controlling fall armyworm as compared to most farmers (46%) in Ethiopia who perceived that chemical spray is effective for the control of fall armyworm. In Ethiopia, 26% of the farmers combined handpicking larvae with insecticide sprays, whilst 15% of the farmers practiced only handpicking. The present study highlights the need to develop management strategies for fall armyworm based on farmers' needs and priorities.
