摘要: 笔者采用自动微量点滴法及测定筒滤纸药膜法测定灭蚊菊酯对蚁、蝇成虫的毒力,用Peet-Grady法测定灭蚊菊酯对蚊、蝇的击倒效果及八氯二丙醚对它的增效作用。灭蚊菊酯对雌成蚊的LD50是0.0673μg/虫,LC50为428mg/m2;对蝇成虫的LD50是0.104μg/虫;对蚊、蝇毒力较EBT弱。配成酊剂对蚊、蝇成虫的击倒中时在剂量为0.6mga·i/m3时是4.25及8.63min;与剂量为0.1mga·i/m3的EBT配剂的击倒速度相近。研究发现,灭蚊菊酯与八氯二丙醚按1:4~6比例复配,对蚊、蝇的击倒活性明显提高。

Abstract: cyanc-2-methy -penten-2-y1-a1-cis.trans-2,2-dimethy-3-(2,2-dichlorvinyl)cuclopropanecarboxylate or JS-88 was synthesized and manufactured in China recently.Its insecticidal activity was tested on Culex pipiens quinquefasciatus and Musca domestica and a lower knockdown and lethal activity were observed in comparision with the bioallethrin's.The knockdown effect was strongly synergised by S-421 at 1:4-6 ratio.
