A study on the acaricidal properties of foam soap containing the essential oil of Chenopodium ambrosioides leaves was carried out on Rhipicephalus lunulatus. Four doses (0.03, 0.06, 0.09, and 0.12 µL of essential oil per gram of soap) and a control (soap without essential oil) with four replications for each treatment were used for in vitro trial. Each replication consisted of 10 ticks in a Petri dish with filter paper impregnated with the foam soap on the bottom. Following in vitro trials, three doses (0.06, 0.09, and 0.12 µL/g) and the control in two replications were selected for in vivo test based on mortality rate recorded from the in vitro trial. Each replication was made up of 10 goats naturally infested with ticks. Results show that soap containing essential oil is toxic to R. lunulatus. The in vivo mortality rate in the control on day 8 was 22.69% whereas the highest dose (0.12 µL/g) killed 96.29% of the ticks on day 8. The LD50 of the foam soap containing essential oil was 0.037 and 0.059 µL/g on day 2 in the laboratory and on the farm, respectively. This indicates the potentially high efficiency of this medicated soap on this parasite.
对含有土荆芥叶精油的泡沫肥皂对扇头蜱的杀螨特性进行了一项研究。体外试验采用四个剂量（每克肥皂含0.03、0.06、0.09和0.12微升精油）和一个对照（不含精油的肥皂），每个处理重复四次。每次重复在一个培养皿中放入10只蜱，培养皿底部铺有浸有泡沫肥皂的滤纸。体外试验后，根据体外试验记录的死亡率，选择三个剂量（0.06、0.09和0.12微升/克）和对照进行两次重复的体内试验。每次重复由10只自然感染蜱的山羊组成。结果表明，含精油的肥皂对扇头蜱有毒性。对照组在第8天的体内死亡率为22.69%，而最高剂量（0.12微升/克）在第8天杀死了96.29%的蜱。含精油的泡沫肥皂在实验室第2天和农场的半数致死剂量分别为0.037和0.059微升/克。这表明这种药皂对这种寄生虫可能具有高效性。
