采用气相色谱仪分析,发现沙柳木蠹蛾雌虫性信息素腺体中存在顺-7-十四碳烯醇(Z7-14:OH)、顺-5-十四碳烯醇乙酸酯(Z5-14:Ac)、顺-7-十四碳烯醇乙酸酯(Z7-14:Ac)和顺-9-十六碳烯醇乙酸酯(Z9-16:Ac)4种成分.通过化学合成获得相应的化合物,对这些标准品进行室内触角电化测定和林间生物测定,评价其对沙柳木蠹蛾的生物活性.结果表明:Z7-14:Ac和Z5-14:Ac按一定比例复配后有明显的引诱活性,在此二者的复配物中加入少量Z7-14:OH,诱蛾量稍有增加;将Z7-14:Ac,Z5-14:Ac和Z7-14:OH以10:8:1的比例配制成总含量为760 μg的诱芯,与三角形诱捕器结合可用于对沙柳木蠹蛾进行诱杀.

The carpenterworm moth, Holcocerus arenicola is a serious pest of desert thicket.Cis-7-tetradecen-1-ol (Z7-14:OH) , cis-5-tetradecen-1-yl acetate (Z5-14:Ac), cis-7-Tetradecen-1-yl acetate (Z7-14:Ac) and cis-9-hexadeceny-1-yl acetate (Z9-16:Ac) were preliminarily identified by gas chromatography (GC) from its sex pheromone gland extracts.These compounds were chemically synthesized in lab and their biological activities were evaluated in lab and field.The results showed that a blend of Z7-14 :Ac and Z5-14 :Ac had strong attractive activity.Addition of Z7-14 :OH to the blend enhanced slightly the trap catches.The synthetic compounds Z7-14:Ac, Z5-14:Ac and Z7-14:OH in a 10 :8:1 ratio at 760 μg per trap dosage, set in a triangle trap, were able effectively to attract and kill H.arenicola.
