摘要:

采用玻片浸渍法测定了依维菌素等4种药剂对二斑叶螨雌成螨的室内毒力,并进行了防治二斑叶螨的田间药效试验。室内测定结果表明,几种药剂对二斑叶螨的毒力顺序为:依维菌素>甲氰菊酯>高效氯氟氰菊酯>螺虫乙酯,其中依维菌素对二斑叶螨的室内毒力最高,其LC50值为0.01 mg/L。田间试验结果表明,0.5%依维菌素乳油9、18 g/hm 2用量,药后3、7、10天对二斑叶螨的防治效果在90%以上,可作为防治二斑叶螨雌成螨的首选药剂。

Abstract:

The laboratory toxicity of ivermectin and other three pesticides to female adult mites of Tetranychus urticae was determined by slide impregnation method, and the field control efficacy test was carried out. The results of indoor toxicity test showed that the toxicity of these four insecticides against Tetranychus urticae was ranked as follows: ivermectin> fenpropathrin>beta-cyhalothrin>spironoethyl ester, and ivermectin exhibited the highest indoor toxicity to Tetranychus urticae with LC50 value of 0.01 mg/L. The results of field experiment showed that the control effect of 0.5% ivermectin EC at 9 and 18 g/hm 2 dosage were more than 90% at 3, 7 and 10 days after the treatment, and it could be used as the first choice to control female adult mites.

Key words: insecticides, Tetranychus urticae Koch, indoor toxicity, field efficacy
