摘要

The fall armyworm Spodoptera frugiperda (J.E. Smith) is an insect pest native to tropical and subtropical regions of the Americas, causing significant yield losses. The present study done in 2017 at the Amhara Region Agricultural Research Institute (ARARI) evaluates the efficacy of certain insecticides against this pest. A laboratory bioassay and field experiment were conducted with 14 insecticides along with an untreated check in a Complete Randomized Design replicated thrice. From the bioassay, thechi-square test revealed that chlorpyriphos ethyl, profenophos+ lambda cyhalothrin, profenophos+ cypermethrin, spinosad and indoxacarb were the best giving maximum larval mortality. In the field experiment, only profenophos+ cypermethrin and spinosad were effective giving maximum mortality of the sixth instar larva in the whorls; these were followed by profenophos+ lambda cyhalothrin and indoxacarb. Whorl application and spraying over the canopy had no significant difference. The results conclude thatspraying over the canopy would be more effective against earlier larval instars since these could not hide in the whorl like those of the sixth instar.

Smith)是一种原产于美洲热带和亚热带地区的虫害,导致产量损失。 2017年在阿哈拉地区农业研究所(Arari)完成了本研究评估某些杀虫剂对该害虫的疗效。用14个杀虫剂进行实验室生物测定和现场实验,并在完整的随机设计中复制三次杀虫剂。从生物测定中,Thechi-Square测试表明,氯吡啶酚乙基,胚乳+λCyhalothrin,Profenophos + cypetmethrin,Spinosad和吲哚虫草是最大的幼虫死亡率。在田间实验中,只有促进型蛋白质+硫酰胺和锭剂有效地在螺旋中产生最大的第六龄幼虫的最大死亡率;这些是胚乳溶液+λ用吲哚肝素和吲哚卡马拉。螺旋施用和喷洒在树冠上没有显着差异。结果总结说,由于这些无法像第六仪器那样藏在螺旋中,因此对冠层进行了更有效的。
