摘要
Spodoptera frugiperda (J E Smith) 是高粱的一种重要害虫，在埃塞俄比亚造成了严重损失。本研究于 2020 年和 2021 年的主要耕种季节在埃塞俄比亚贡达尔的梅特马试验场进行，采用随机完全区组设计，三次重复，以确定选定的杀虫剂对 S. frugiperda 幼虫的适当杀虫率。使用的 Melkam 品种播种量为 15 kg ha-1，小区面积为 22.5 m2。按照公司推荐的比例喷洒 Proven 和 Agrolambacin 的地块降低了幼虫发生率，并提高了谷物产量。成本效益分析表明，喷洒普罗旺斯的净效益最高（63410.3 ETB ha-1），其次是 Agrolambacin 55535 ETB ha-1。
Efficacy of Insecticides against Fall Army Worm Spodoptera frugiperda (J E Smith) on Sorghum
Spodoptera frugiperda (J E Smith) is an important pest of sorghum, which is causing heavy losses in Ethiopia. This study was conducted at the Metema experimental site Gondar, Ethiopia during main cropping seasons of 2020 and 2021 to determining appropriate rate of selected insecticides against S. frugiperda larvae using randomized complete block design with three replications. Melkam variety used at a seed rate of 15 kg ha-1 and plot size of 22.5 m2 was used. Plots sprayed with Proven and Agrolambacin in company recommendation rate reduced the incidence of larvae and gave higher grain yield. Cost benefit analysis showed that maximum net benefit (ETB 63,410.3 ha-1) was obtained with followed by Agrolambacin 55535 ETB ha-1.
