| 摘 要： | 速杀威是由四川成都宏威制药有限公司研制的一种植物性杀虫剂．低浓度５０ｐｐｍ 的速杀威对萝卜蚜（Ｒｈｏｐａｌｏｓｉｐｈｕｍ ｐｓｅｕｄｏｂｒａｓｓｉｃａｅ）的毒力为９３．０２％，与克 敌乐尔１０８ｐｐｍ以及乐果２００ｐｐｍ的毒力相当．当速杀成浓度为１００ｐｐｍ时，其毒力 高于乐果２００ｐｐｍ，而与克敌乐尔２７０ｐｐｍ相当。速杀威ｌ００ｐｐｍ对茶二叉蚜（Ｔｏｘｏ ｐｔｅｒａ ａｕｒａｎｔｉｉ）的毒力与乐果２００ｐｐｍ以及克敌乐尔２７０ｐｐｍ相似。速杀威１００ｐｐｍ 对麦圆蜘蛛（Ｐｅｎｔｈａｌｅｕｓ ｍａｊｏｒ）的毒力与乐果２６６ｐｐｍ相当。速杀威对小绿叶蝉 （Ｅｍｐｏａｓｃ ｆｌａｖｅｓｃｅｎｓ）的ＬＣ５０值为２．１４±０.６８２５ｐｐｍ，低于克敌乐尔的ＬＣ５０３．３１ ±０．１５８６ｐｐｍ和乐果的ＬＣ５０４． ２７± ０． ５６５ｐｐｍ值．

| Abstract: | Sushawei(SSW), produced by Hongwei Company (group), is natural vegtable pesticide. At low concentration 50,ppm, its,virtulence to the aphid (Rhopalosiphum pseudobrassicae)was 93. 02%, similar to those of Kediluole 108 ppm and dimethoate 200ppm. The virulence of Sushawei at concentration 100ppm. however, was higher than dimethoate. 200 ppm and similar to Kedilaole 270 ppm. For the tea aphid (Toxoptera aurantii),virulence of Sushawei at 100ppm was equal to those of dimethoate 200ppm and Kediluole 270ppm.There was no difference of virulence to the green wheat mite (Penthaleus major)between sushawei 100ppm and dimethoate 266ppm.LC50 of Sushawei to the tea green fly (Empoasca flavescens )was 2.14± 0.6825ppm,lower than Kediluole (LC503.31±0.1586)and dimethoate (LC50 4.27± 0.565). |
