柴油及其与阿维菌素复配对柑橘全爪螨卵的作用

Effect of Diesel Oil and its Mixture with Abamectin on the Eggs of Panonychus citri McGregor

室内测定了柴油对柑橘全爪螨卵的毒力及其与阿维菌素复配植物油基新型乳油的杀卵作用。结果表明,柴油对柑橘全爪螨卵的LC50为2790.39μg/mL;两种柴油与阿维菌素复配新型乳油1000、750和500倍液3种浓度下的杀卵率均高于90%,其中添加了印楝油的复配剂3浓度的杀卵率与对照药剂24%螺虫乙酯SC 3000倍液相当。

Toxicity of diesel oil against eggs of Panonychus citri and ovicidal action of diesel oil mixed with abamectin were determined in the lab.It was shown that,for the contact toxicity of diesel oil to eggs of Panonychus citri,the LC50 value was 2790.39 μg/mL.Besides,the ovicidal rate of two kinds of new type EC of abamectin-diesel oil combination were all above 90% treated with 1000,750 and 500 times diluted emulsion.Especially,the ovicidal rate of mixture at three concentration as above,which added neem oil,were as high as control pesticide of spirotetramat.So the new type EC of diesel oil mixed with abamectin had extensive application prospect in controlling pest mite.
