In laboratory trail-following bioassays of Argentine ant workers,Iridomyrmex humilis (Mayr), the geometric isomer, (E)-9-hexadecenal, of the trail pheromone component (Z)-9-hexadecenal elicited insignificant trail following as did the potentially more stable formate analogs, (Z)-7-tetradecenyl formate, (E)-7-tetradecenyl formate, and tetradecyl formate. Further, in direct choice tests, workers showed no preference for gaster extract trails (0.002 ant equiv/cm) over trails of (Z)-9-hexadecenal (0.2 ng/cm). Moreover, a 10-fold increase in synthetic trail concentration to 2.0 ng/cm caused (Z)-9-hexadecenal trails to be significantly preferred over gaster extract trails by trail-following ants.
在对阿根廷蚂蚁工蚁的实验室追踪生物测定中,(Z)-9-十六碳烯醛的几何异构体(E)-9-十六碳烯醛,以及可能更稳定的甲酸盐类似物(Z)-7-十四碳烯基甲酸盐、(E)-7-十四碳烯基甲酸盐和十四烷基甲酸盐,对追踪行为的激发作用不明显。此外,在直接选择测试中,工蚁对腹部提取物(0.002 蚂蚁当量/cm)的轨迹没有表现出明显的偏好,而对(Z)-9-十六碳烯醛(0.2 ng/cm)的轨迹也没有偏好。此外,合成轨迹浓度增加 10 倍至 2.0 ng/cm 时,(Z)-9-十六碳烯醛的轨迹明显比腹部提取物的轨迹更受追踪蚂蚁的青睐。
