沙棘木蠹蛾性信息素林间诱蛾活性试验

为比较沙棘木蠹蛾性信息素不同配方的诱集效果，该文利用人工合成的性信息素组分顺7-十四碳烯乙酸酯(Z7-14:Ac)、反3-十四碳烯乙酸酯(E3-14:Ac) 和反7-十四碳烯乙酸酯(E7-14:Ac)按照不同比例配置的4种配方进行了野外诱集试验.结果表明:4组不同配方的性信息素均具有较强的诱集效果，其中平均诱蛾量最高的达17头/诱捕器，日诱蛾量最高的为11头/d，持效期达26 d，不同配方的有效诱捕距离分别达100和150 m.通过比较两种不同诱捕器的野外诱集效果发现:沙棘木蠹蛾实用新型诱捕器的诱蛾效果稍差于三角形诱捕器，但其具有使用方便、易于操作、可长时间使用等特点，诱捕器的最佳悬挂高度为1 m.用性信息素诱杀害虫作为一种高效、无毒、无污染的新方法为沙棘木蠹蛾的综合防治提供了一条崭新的途径. 

Field trapping trials of sex pheromone for Holcocerus hippophaecolus ( Lepidoptera : Cossidae )

Four sorts of sex pheromones that were mixed at different ratios with three kinds of main sex pheromone components of seabuckthorn carpenter moth: (Z)-7-tetradecenyl acetate (Z7-14:Ac), (E)-3-tetradecenyl acetate (E3-14:Ac) and (E)-7-tetradecenyl acetate (E7-14:Ac), were experimented in the field. The results showed that four kinds of pheromones all had strong, attractive effects on male moths. The largest numbers of moths trapped were 17 males per trap and 11 males per day. The most effective pheromone can last up to 26 days. The effective trapping distances of the different attractants reached 100 and 150 m respectively. Comparing the effects of the two traps to capture male carpenter moths, it is found that the new and practical trap is slightly less effective than the triangle trap, while it is convenient, easily operated and can last a long time. The best height to hang the trap is 1 m. So the application of this sex pheromone provides a new technique for the integrated control of H. hippophaecolus since it is highly effective, nonpoisonous and non-polluting.
