Abstract

The toxicity of cypermethrin was determined in five different soft tick strains of Argas persicus Oken and Ornithodoros lahorensis Neuman by topical application method. The O. lahorensis Bij, O. lahorensis west O1, O. lahorensis Mesh, A. persicus Lor, A. persicus West Ap strains were collected from Bijar, Kurdistan province, Takab, Western Azerbaijan province, Meshkinshar, Ardebil province, Khoramabad, Lorestan province, Takab, Western Azerbaijan province of different areas of Islamic Republic of Iran, respectively during 2004 and 2005. In the topical application bioassay, the average LD50 of O. lahorensis Bij, West O1, Mesh and A. reflexus Lor and West AP strains were 0.03, 0.04, 1.7, 0.7 and 1.7 microg tick(-1), respectively and the steep slopes of dose-response curves indicated that the field population of these soft tick strains were homogenous in response to cypermethrin. Comparison of the resistance ratio of collected strains with susceptible strain showed a resistance ratio of 56.7 and 2.4-folds for cypermethrin in O. lahorensis Mesh and A. reflexus West Ap strains, whereas the O. lahorensis West O1 completely susceptible to cypermethrin.

摘要

通过局部涂抹法测定了氯氰菊酯对波斯锐缘蜱（Argas persicus Oken）和拉合尔钝缘蜱（Ornithodoros lahorensis Neuman）五个不同软蜱品系的毒性。拉合尔钝缘蜱Bij品系、拉合尔钝缘蜱西O1品系、拉合尔钝缘蜱Mesh品系、波斯锐缘蜱Lor品系、波斯锐缘蜱西Ap品系分别于2004年和2005年从伊朗伊斯兰共和国不同地区的库尔德斯坦省Bijar、西阿塞拜疆省Takab、阿尔达比勒省Meshkinshahr、洛雷斯坦省霍拉马巴德、西阿塞拜疆省Takab采集。在局部涂抹生物测定中，拉合尔钝缘蜱Bij品系、西O1品系、Mesh品系以及波斯锐缘蜱Lor品系和西Ap品系的平均半数致死剂量（LD50）分别为0.03、0.04、1.7、0.7和1.7微克/蜱，剂量反应曲线的陡峭斜率表明这些软蜱品系的田间种群对氯氰菊酯的反应是均匀的。将采集的品系与敏感品系的抗性比率进行比较，结果显示拉合尔钝缘蜱Mesh品系和波斯锐缘蜱西Ap品系对氯氰菊酯的抗性比率分别为56.7倍和2.4倍，而拉合尔钝缘蜱西O1品系对氯氰菊酯完全敏感。
