摘要: 研究了3类助剂(矿物油、高级脂肪酸、非离子表面活性剂)、两种给药方式(点滴法、浸渍法)对非内吸性杀虫剂高效氯氰菊酯在粘虫Mythimna separata表皮渗透性的影响。证明对适宜的助剂和给药方式而言,该渗透性在一定范围内与药剂中助剂含量和给药后的时间成正相关。助剂的一些组合对渗透性具有一定的协同作用。

Abstract: The effects of various adjuvants (mineral oil, higher aliphatic acid and nonionic surfactant) and two application methods (topical and immersion) on the penetration of beta-cypermethrin across the armyworm (Mythimna separata Walker) epidermis were studied. The results showed that the penetration was directly correlated with the concentration of adjuvants and with the time course after application, within the definite range of adjuvant concentration. A coordination effect of two types of adjuvant on the penetration was found.
