Abstract

Six pesticides and two spray oils were tested against Polyphagotarsonemus latus. The chemicals were evaluated under laboratory conditions, requiring the development of a novel bioassay method, which is reported here. The pesticide toxicities fell into three distinct groups, namely abamectin, conventional pesticides and oils. The relative pesticide toxicities at the LC50 level were abamectin 4.9 x 10(-8) g ai 1(-1), endosulfan 1.1 x 10(-3) g ai 1(-1), fenpyroximate 2.3 x 10(-3) g ai 1(-1), pyridaben 4.1 x 10(-3) g ai 1(-1), tebufenpyrad 4.4 x 10(-3) g ai 1(-1), dicofol 4.5 x 10(-3) g ai 1(-1), petroleum spray oil 3.4 x 10(-1) g ai 1(-1) and canola oil 4.1 x 10-(1) g ai 1(-1). The calculation of the LC99.9 values allows for resistance monitoring in P. Latus and the suggested discriminating concentrations are abamectin 1.0 x 10(-4) g ai 1(-1); endosulfan, pyridaben and dicofol 1.0 x 10(-1) g ai 1(-1) fenpyroximate and tebufenpyrad 5.0 x 10(-1) g ai 1(-1).

摘要

对六种杀虫剂和两种喷雾油进行了防治侧多食跗线螨的测试。这些化学药剂是在实验室条件下进行评估的，这需要开发一种新的生物测定方法，本文对此进行了报道。农药毒性分为三个不同的组，即阿维菌素、传统农药和油类。在LC50水平下的相对农药毒性分别为：阿维菌素4.9×10⁻⁸克有效成分/升，硫丹1.1×10⁻³克有效成分/升，唑螨酯2.3×10⁻³克有效成分/升，哒螨灵4.1×10⁻³克有效成分/升，四螨嗪4.4×10⁻³克有效成分/升，三氯杀螨醇4.5×10⁻³克有效成分/升，石油喷雾油3.4×10⁻¹克有效成分/升，菜籽油4.1×10⁻¹克有效成分/升。计算LC99.9值有助于监测侧多食跗线螨的抗性，建议的区分浓度为：阿维菌素1.0×10⁻⁴克有效成分/升；硫丹、哒螨灵和三氯杀螨醇1.0×10⁻¹克有效成分/升，唑螨酯和四螨嗪5.0×10⁻¹克有效成分/升。
