摘要
长角血蜱Ｈａｅｍａｐｈｙｓａｌｉｓｌｏｎｇｉｃｏｒｎｉｓ的交配行为包括７个时期，行为的完成依赖于性信息素的调节。生物测定表明：雄蜱的行为反应受雌蜱分泌的性信息素影响。堵塞雌蜱盾窝其行为受到抑制，点滴２，６ＤＣＰ或雌蜱盾窝腺提取物则被恢复。用气相色谱法测定了雌蜱盾窝腺中２，６ＤＣＰ的含量；吸血后１～２天含量最高（１１１２ｎｇ／只）；吸血后３～５天即交配前下降交维持在一较恒定的水平；吸血后６～７天即交配后明显降低；饱血后检测不到２，６ＤＣＰ。２，６ＤＣＰ是长角血蜱性信息素的一种成分。
The mating behaviour of Haemaphysalis longicornis consisted of 7 stages. Bioassay suggested that male response was regulated by the sex pheromone secreted by females. Blocking up female fovea, male response was inhibited; while topical application of 2,6 DCP or extract of female foveal glands could restore it. A highest level of 2,6 DCP content (11 12ng/individual) was reached during the 1st～2nd day after attachment when analysis by GC. The amounts of 2,6 DCP declined on the 3rd～5th day after attachment just before mating, but maintained at a relatively constant level. After mating, it declined singificantly and became undetectable after engorgement.
