本文用气相色谱法对长角血蜱饱血若虫，饥饿、吸血后和饱血后成虫盾窝腺中性信息素２，６－二氯酚（２，６－ＤＣＰ）含量进行了测定：２，６－ＤＣＰ仅存在于成虫，若虫中检测不到；雄虫只在吸血期产生２，６－ＤＣＰ，但含量甚微（约１ｎｇ／只），其生物学作用尚不清楚；雌虫性信息素的生物合成开始于成虫蜕出后４—５ｄ，之后其含量不断增加，吸血前后达到高峰，２，６－ＤＣＰ最高含量为１１．１２ｎｇ／只；吸血后３ｄ开始下降，但吸血后３—５ｄ即交配前保持在一较恒定水平。盾窝腺中２，６－ＤＣＰ含量的下降与雌虫不断释放以吸引雄虫有关，此期内并有新的信息素合成；吸血后６—７ｄ急剧下降；饱血后下降为零。本文用气相色谱法对长角血蜱饱血若虫，饥饿、吸血后和饱血后成虫盾窝腺中性信息素２，６－二氯酚（２，６－ＤＣＰ）含量进行了测定：２，６－ＤＣＰ仅存在于成虫，若虫中检测不到；雄虫只在吸血期产生２，６－ＤＣＰ，但含量甚微（约１ｎｇ／只），其生物学作用尚不清楚；雌虫性信息素的生物合成开始于成虫蜕出后４—５ｄ，之后其含量不断增加，吸血前后达到高峰，２，６－ＤＣＰ最高含量为１１．１２ｎｇ／只；吸血后３ｄ开始下降，但吸血后３—５ｄ即交配前保持在一较恒定水平。盾?
In this paper, the content of 2,6-dichlorophenol (2,6-DCP) in adult Dunnock’s gonads was determined by gas chromatography after saturated with blood-nymphs, starved, , 6-DCP was only present in adults and not detected in nymphs; male only produced 2,6-DCP during the blood-sucking period, but the content was very low (about 1ng / bird); its biological role was unclear; The biosynthesis of pheromone began 4-5 days after the adult molting, after which its content increased continuously, reached the peak before and after vampire, the highest content of 2,6-DCP was 11.12ng / only; 3d began to decline after vampire, but after vampire 3 -5d that before mating to maintain a more constant level. The decline of 2,6-DCP content in shield foramina was related to the continuous release of females to attract male insects. During this period, new pheromones were synthesized, and dropped sharply 6-7 days after blood-sucking.
