摘　　要：【目的】本研究旨在通过测定苯酚及其衍生物对台湾乳白蚁Coptotermes formosanus踪迹行为的影响,筛选对台湾乳白蚁具有踪迹活性的化合物,为白蚁引诱剂的研发提供新的思路。【方法】在定性滤纸上画Y型路径,用不同浓度的苯酚及12种苯酚衍生物沿茎和其中的一条分枝划线,另一条分支仅用不含化合物的丙酮划线;测试台湾乳白蚁工蚁和兵蚁沿化合物划线爬行距离,比较工蚁和兵蚁的踪迹行为。【结果】苯酚(0.05,0.5和5μg/cm)、对氯苯酚(0.005,0.05,0.5,5和50μg/cm)、苯甲酸苯酯(0.0005,0.005,0.05,0.5,5和50μg/cm)、乙酸苯酯(0.5,5和50μg/cm)、4-羟基苯甲醛(0.5,5和50μg/cm)、甲基苯乙基醚(5和50μg/cm)、苯乙醚(50μg/cm)和2-氟苯酚(0.5和5μg/cm)共8种化合物对台湾乳白蚁工蚁具有踪迹活性(平均爬行距离≥3.0 cm);此外,台湾乳白蚁工蚁和兵蚁沿苯酚(0.5μg/cm)、对氯苯酚(0.05μg/cm)或苯甲酸苯酯(0.5μg/cm)划线路径的爬行距离均无显著差异,且踪迹行为相似。【结论】苯酚及多种苯酚衍生物对台湾乳白蚁具有踪迹活性,但它们与此前报道的白蚁踪迹信息素具有不同的化学结构,具有作为白蚁引诱剂的应用潜力。【Aim】This study aims to investigate the effect of phenol and its derivatives on the trail-following behavior of the Formosan subterranean termite,Coptotermes formosanus,and screen compounds that have the trail-following activity for C.formosanus,so as to provide new insights for developing termite attractants.【Methods】A Y-shaped path was drawn on qualitative filter paper,with the stem and one branch drawn with varying concentrations of phenol or 12 phenol derivatives,while the other branch was drawn with chemical-free acetone.The trail-following distance of C.formosanus workers and soldiers in response to each compound was measured and the tail-following behaviors of workers and soldiers were compared.【Results】Eight compounds,including phenol(0.05,0.5 and 5μg/cm),p-chlorophenol(0.005,0.05,0.5,5 and 50μg/cm),phenyl benzoate(0.0005,0.005,0.05,0.5,5 and 50μg/cm),phenyl acetate(0.5,5 and 50μg/cm),4-hydroxy benzaldehyde(0.5,5 and 50μg/cm),2-phenylethyl methyl ether(5 and 50μg/cm),ethyl phenyl ether(50μg/cm),and 2-fluorophenol(0.5 and 5μg/cm),showed the trail-following activities for C.formosanus workers(mean tail-following distance≥3.0 cm).In addition,no significant differences were observed in the trail-following distance between worker and soldier termites along paths drawn with phenol(0.5μg/cm),chlorophenol(0.05μg/cm),or phenyl benzoate(0.5μg/cm),and worker and soldier termites showed similar trail-following behaviors.【Conclusion】Phenol and multiple phenol derivatives have trail-following activities for C.formosanus.These compounds have different chemical structures from previously reported trail-following chemicals in termites,and have the potential to be used as termite attractants.
