ABSTRACT To examine selective effectiveness of specific pesticides on the citrus spider mites and their predator, we evaluated the contact toxicity of different plant-derived pesticides including dishwashing liquid, Dayabon, Palizin, Palizin + Citrol oil, Tondexir + Bartar soap, cpirodiclofen, spiromesifen, pyridaben, chlorpyrifos-ethyl and abamectin and control on the adult of Tetranychus urticae and Panonychus citri, Panonychus ulmi and their predator, Stethorus gilvifrons in the semi-field conditions. The results revealed that at 24, 48 and 72 h after treatment, Tondexir treatment of 3 ml/L + Bartar 1ml/L had the highest mortality rate on the T. urticae, P. citri, and P. ulmi. This value was 98.13, 84.48, and 80.62%, respectively, for 72 h after treatment for these mites. In addition to the mentioned cases, this treatment caused 72.88% mortality in the larvae and 16.13% in the adult predator during 72 h after treatment, while at the same time, the rate of mortality of chlorpyrifos-ethyl and abamectin treatments on ladybirds was 100%. The results of this study showed that herbal treatments have a high efficiency for integrated management programmes of the major harmful citrus mites and have little impact on their natural enemies and can replace the high-risk chemical pesticides.

选定的植物衍生农药在半田条件下对柑橘叶螨（Acari：Tetranychidae）及其捕食者 Stethorus gilvifrons 的毒性

摘要 为了检验特定杀虫剂对柑橘叶螨及其捕食者的选择性有效性，我们评估了不同植物来源的杀虫剂的接触毒性，包括洗碗液、Dayabon、Palizin、Palizin + Citrol oil、Tondexir + Bartar 肥皂、cpirodiclofen、spiromesifen、哒螨灵、乙基毒死蜱和阿维菌素，以及在半田间条件下对叶螨和柑橘全爪爪、全爪爪及其捕食者 Stethorus gilvifrons 成虫的控制。结果显示，在治疗后24、48和72 h，Tondexir 3 ml/L + Bartar 1 ml/L对荨麻疹、柑橘假单胞菌和乌梅假单胞菌的死亡率最高。对这些螨虫进行处理 72 小时后，该值分别为 98.13、84.48 和 80.62%。除上述病例外，这种治疗还造成了 72 起。处理后72小时内幼虫死亡率为88%，成年捕食者死亡率为16.13%，同时乙基毒死蜱和阿维菌素处理对瓢虫的死亡率为100%。本研究结果表明，中草药处理对柑橘主要有害螨类的综合治理效果较好，对其天敌影响小，可替代高危化学农药。
