聚集信息素,aggregation pheromone
1)aggregation pheromone聚集信息素
1.) produce a sex-specific compound, ethyl-4-methyl octanoate(C) which is anaggregation pheromone.雄性椰树犀牛甲虫分泌一种特别的化合物———4-甲基-正辛烷酸乙酯(C),它是一种聚集信息素,合成这种信息素包括3步反应;合成2-甲基已烯-3-醇(A)收率为85%,合成4反-甲基-正辛烷烯酸乙脂(B)收率为84%,合成4-甲基-正辛烷酸乙脂(C)收率为99。
2.Theaggregation pheromones can not only lead to aggregation,but also modify the density of aggregation.聚集信息素不仅具有引诱聚集的作用,其种类和数量还具有调节其聚集密度的效应。
3.The activity ofaggregation pheromones from different sources in the Oriental migratory locusts Locusta migratoria manilensis was assayed by electroantennogram (EAG).采用触角电位测定仪器测定不同来源的东亚飞蝗Locustamigratoriamanilensis聚集信息素的生理活性 ,结合行为生物测定的结果分析表明 :来源于粪便中的聚集信息素的活性较高 ,同时 ,使用较高极性溶剂抽提制备蝗蝻粪便中的信息素和采用中极性的溶剂制备成蝗粪便中的聚集信息素 ,其信息素的活性均较高 ;利用低极性溶剂从东亚飞蝗粪便中制备得到的聚集信息素的活性较低 ;采用层析柱吸附浓缩飞蝗粪便中自然挥发出的气味和飞蝗体表的气味并进行生物测定后表明 ,其EAG活性普遍较低 ;因此 ,来自于飞蝗粪便中的且采用合适的溶剂抽提制备的聚集信息素 ,具有较高的生物学活性。
