摘要:

采用玻片浸渍法,室内测定了11种常用药剂对北京地区蔬菜上朱砂叶螨的毒力效果。结果表明,阿维菌素对朱砂叶螨雌成螨毒力最高,其致死中浓度LC50为0.0007mg/L,甲氨基阿维菌素苯甲酸盐和氧苦?内酯的毒力较高,LC50分别为0.0130 mg/L和0.1461 mg/L;哒螨灵和虫螨腈的效果次之,其LC50分别为21.3122mg/L和34.8519 mg/L。其他药剂如克螨特、高效氯氟氰菊酯和多杀菌素对雌成螨毒性较低,螺螨酯、氯虫苯甲酰胺和噻螨酮对朱砂叶螨雌成螨毒力很差。

Abstract:

The toxicity bioassay of 11 common acaricides to the adult females of carmine spider mites, Tetranychus cinnabarinus, in vegetables in Beijing area was carried out using slide-dip method in the laboratory. The results showed that abamectin had the highest toxicity with the LC50 value of 0.0007mg/L. Emamectin benzoate and Oxymatrine?Prosuler also showed higher toxicity to the mites, with the LC50 of 0.0130mg/L and 0.1461mg/L, respectively. Chlorantraniliprole, Pyridaben and Chlorfenapyr exhibited a little of lower toxicity, having the LC50 of 21.3122mg/L and 34.8519mg/L, respectively. The other acaricides had low toxicity, and Envidor, Chlorantraniliprole and Hexythiazox showed the lowest toxicity to the adult females of spider mites.
