为了提高粘蜱诱捕器对血红扇头蜱（Rhipicephalus sanguineussensu lato（s.l.）将性信息素（SP）、聚集信息素（AP）以及最佳浓度的SP + AP组合浸渍在蒸汽贴片中。不同阶段的R.血红湖使用皮氏培养皿生物测定法评估昆虫（即幼虫、成虫和成虫）对信息素的敏感性。将浸渍的蒸汽贴剂保留2个月，并重新评估其有效性。在随后的田间试验中，将浸渍有信息素的蒸汽贴片作为诱饵放置在用于控制狗窝中蜱的竹（Bambusa vulgaris）粘性诱捕器中。血红湖而SP则能有效地吸引未取食和取食的雄虫。血红湖田间试验结果表明，幼虫、成虫和雌虫的取食和摄食均能使幼虫、雌虫和雌虫的摄食量增加。血红湖对AP浸渍蒸汽贴片的吸引力大于SP和AP + SP浸渍蒸汽贴片。喂食和未喂食的雄蜱被单独的SP有效地引诱。SP + AP的组合没有表现出强的相加或协同效应。
Vapour patches dispensing pheromones were evaluated as lures to increase the attractiveness of sticky tick traps forRhipicephalus sanguineussensu lato (s.l.). Sex pheromone (SP), assembly pheromone (AP) and a combination of SP + AP at optimal concentrations were impregnated in vapour patches. The responses of the different stages ofR. sanguineuss.l. (i.e.larvae, nymphs and adults) to the pheromones were evaluated using a Petri dish bioassay. The impregnated vapour patches were retained as such for a period of two mo and their efficacy was reassessed. In a subsequent field trial, pheromone impregnated vapour patches were placed as lures in bamboo (Bambusa vulgaris) sticky traps designed for the control of ticks in dog kennels.In vitroAP impregnated vapour patches were effective in attracting the different life stages ofR. sanguineuss.l. whereas SP was effective in attracting the unfed and fed male stages ofR. sanguineuss.l. The field trial revealed that questing and engorged larvae, nymphs and females ofR. sanguineuss.l. were attracted more towards AP impregnated vapour patches than SP and AP + SP impregnated vapour patches. Fed and unfed male ticks were lured effectively by SP alone. The combination of SP + AP revealed no potent additive or synergistic effect.
