| 摘 要： | 在室内采用浸叶法测定了氧化乐果、杀扑磷、毒死蜱、灭多威、吡虫啉、高效氯氰菊酯、阿维菌素及矿物油对新菠萝灰粉蚧若虫的毒力,结果表明处理24h后,对1龄若虫的毒力大小顺序为:毒死蜱>灭多威>高效氯氰菊酯>氧化乐果>吡虫啉>杀扑磷>阿维菌素>矿物油;对2龄若虫的毒力大小顺序为:毒死蜱>灭多威>吡虫啉>氧化乐果>杀扑磷>高效氯氰菊酯>阿维菌素>矿物油;对3龄若虫的毒力大小顺序为:毒死蜱>灭多威>吡虫啉>杀扑磷>高效氯氰菊酯>氧化乐果>阿维菌素>矿物油。测定了氧化乐果、杀扑磷、毒死蜱、灭多威、吡虫啉及高效氯氰菊酯对新菠萝灰粉蚧雌成虫的毒力,结果表明处理24h后,对雌成虫的毒力大小顺序为:杀扑磷>毒死蜱>吡虫啉>高效氯氰菊酯>氧化乐果>灭多威。结果表明毒死蜱、灭多威、吡虫啉和杀扑磷等可作为控制新菠萝灰粉蚧发生的药剂。

| Abstract: | The toxicity of Omethoate,Methidathion,Chlorpyrifos,Methomyl,Imidacloprid,Beta-cypermethrin,Abamectin and Petroleum oil to the nymphs of Dysmicoccus neobrevipes Beardsley were studied by using dip method in the laboratory.The study results showed that the toxicity order of these insecticides to the 1st-instar nymph of D.neobrevipes was Chlorpyrifos>Methomyl>Beta-cypermethrin>Omethoate>Imidacloprid>Methidathion>Abamectin>Petroleum oil,and the toxicity order of these insecticides to the 2nd-instar nymph was Chlorpyrifos>Methomyl>Imidacloprid>Omethoate>Methidathion>Beta-cypermethrin>Abamectin>Petroleum oil,and the toxicity order of these insecticides to the 3rd-instar nymph was Chlorpyrifos>Methomyl>Imidacloprid>Methidathion>Beta-cypermethrin>Omethoate>Abamectin>Petroleum oil.The toxicity order of Omethoate,Methidathion,Chlorpyrifos,Methomyl,Imidacloprid and Beta-cypermethrin to the female adults of D.neobrevipes was Methidathion>Chlorpyrifos>Imidacloprid>Beta-cypermethrin>Omethoate>Methomyl.The results showed that Chlorpyrifos,Methomyl,Imidacloprid and Methidathion might be use as pesticides of D.neobrevipes management. |
