摘要
针对当前杀螨剂毒力测定标准的适用局限性提出了适合所有杀螨剂类型毒力测定的新标准建议,并以水培花生叶培养二斑叶螨Tetranychus urticae Koch进行Potter喷雾法毒力测定为例,描述了测定其不同螨态的4种室内毒力的操作要点,阐明对螨类这种世代历期短、繁殖能力强、经济危害地位重要的特殊生物类群,采用新的杀螨剂毒力测定标准,不仅对正确评价杀螨剂的作用特性、指导科学合理用药非常必要,而且操作上是可行的。
A new standard for measuring acaricide virulence that can be applied to all kinds of acaricide is proposed to rectify the limitations of the current standard.An example of the application of the new standard is provided in which the Potter spray method was used to test acaricide virulence on 4 different stages of Tetranychus urticae Koch raised on groundnut leaves in a laboratory.The results indicate that the proposed new standard can not only accurately evaluate the effectiveness of acaricides but is also practical to use.
