背景：除了性信息素外，信息素在害虫防治中的应用在很大程度上尚未被探索。高浓度的踪迹信息素会扰乱蚂蚁的踪迹跟踪和觅食，因此合成的踪迹信息素可以成为害虫蚂蚁的新型控制剂。本研究采用合成尾迹信息素、杀虫诱饵或两者对小面积区域（100平方米的城市住宅花园）进行了为期一年的处理，以开发一种新的控制入侵阿根廷蚁Linepithema humile（Mayr）的方法。结果：仅通过合成尾迹信息素和杀虫诱饵的联合处理，蚂蚁种群就可以维持在低于或接近初始水平。事实上，联合处理区的蚂蚁数量几乎总是最低的。在整个研究期间，用合成线索信息素或杀虫诱饵处理过的地块中的蚂蚁种群与未处理的地块相似。结论：联合处理可能是比传统方法更有效、更环保的控制入侵蚂蚁的方法。通过杀虫诱饵消灭蚂蚁和通过信息素抑制再次感染可能是联合作用的机制。这是第一项显示合成踪迹信息素对蚂蚁种群有显着影响的研究。版权所有© 2011 中国化工学会
BACKGROUND:Except for sex pheromones, use of pheromones in pest management has been largely unexplored. A high concentration of trail pheromone disrupts ant trail following and foraging, and thus synthetic trail pheromone can be a novel control agent for pest ants. In this study, a year‐long treatment of small areas (100 m2plots of urban house gardens) with synthetic trail pheromone, insecticidal bait or both was conducted to develop a novel control method of the invasive Argentine antLinepithema humile(Mayr).RESULTS:The ant population could be maintained lower than or similar to the initial level only by combined treatment with synthetic trail pheromone and insecticidal bait. Actually, the ant population was nearly always lowest in combination treatment plots. Throughout the study period, the ant population in plots treated with either one of synthetic trail pheromone or insecticidal bait remained similar to no‐treatment plots.CONCLUSIONS:Combination treatment may be a more effective and environmentally friendly method for controlling invasive ants than conventional methods. Extermination of ants by insecticidal bait and inhibition of re‐infestation by pheromone may be the mechanism of the combination effect. This is the first study to show a significant effect of synthetic trail pheromone on ant population. Copyright © 2011 Society of Chemical Industry
