During the period of major tick activity, in April and May 1998, in the Saint-Maixent l'Ecole area of Poitou, a comparative study was carried out in order to evaluate the protective effect of garments impregnated with permethrin cis/trans 25/75. Three groups of soldiers made up respectively of 208, 218 and 427 men were involved for 2 or 3 days in this experiment. Respectively 107, 107 and 215 wore impregnated uniforms. Out of a total of 319 ticks, 3 were lxodes ricinus, 305 Dermacentor marginatus and 11 D. reticulatus. There was a significant difference in both the intensity (number of ticks per individual, P < 0.0001) and prevalence (number of individuals with ticks, P < 0.001) of ticks on individuals between impregnated and non impregnated uniforms. The repellent effect of permethrin on ticks was observed at the site of preferential tick attachment (normally the head of the host for these two species of Dermacentor in France) where the number of ticks was significantly lower in impregnated uniforms.
在1998年4月和5月蜱虫活动频繁的时期，在普瓦图的圣马克森莱科勒地区，开展了一项比较研究，以评估顺式/反式比例为25/75的氯菊酯浸渍服装的防护效果。三组士兵分别由208名、218名和427名男性组成，参与了为期2或3天的该实验。分别有107名、107名和215名穿着浸渍制服。在总共319只蜱虫中，有3只为蓖麻硬蜱，305只为边缘革蜱，11只为网纹革蜱。浸渍制服和未浸渍制服的人员身上蜱虫的强度（每人蜱虫数量，P<0.0001）和患病率（有蜱虫的人员数量，P<0.001）均存在显著差异。在蜱虫优先附着的部位（在法国，这两种革蜱通常优先附着在宿主头部）观察到氯菊酯对蜱虫的驱避作用，浸渍制服上的蜱虫数量明显较少。
