室内采用Y型嗅觉仪测定不同浓度（1.0×10^-6，1.0×10^-5，1.0×10^-4和1.0×10^-3 mL/mL）水杨醛、水杨酸甲酯、苯乙醛、苯甲醛、桂醇5种化合物对酪蝇Piophila casei(L.)成虫的引诱效果。结果表明：1.0×10^-6和1.0×10^-5 mL/mL苯乙醛，1.0×10^-6 mL/mL苯甲醛，1.0×10^-5和1.0×10^-4 mL/mL水杨醛均对雌、雄虫表现明显的引诱效果。1.0×10^-3mL/mL苯乙醛、水杨醛和苯甲醛对酪蝇雌、雄虫具有明显的驱避效果。桂醇和水杨酸甲酯在所测试的浓度范围内对雄虫具有明显的驱避效果。水杨酸甲酯在浓度为1.0×10^-6 mL/mL对雌虫有明显的引诱效果，其它浓度均对雌虫有明显的驱避效果。桂醇对雌虫有明显的驱避效果。这表明在高浓度时芳香物质对酪蝇成虫有驱避效果，在低浓度时对酪蝇成虫有引诱效果。

Choice responses of skipper cheese adults, Piophila casei(L.), to five kinds of aromatic volatile including salicylaldehyde, methyl salicylate, phenylacetaldehyde, benzaldehyd, and cinnamyl alcohol at different concentration (1.0×10^-6, 1.0×10^-5, 1.0×10^-4, 1.0×10^-3 mL/mL) were conducted using Y_tube olfactometer in laboratory. The results showed that 1.0×10^-6 and 1.0×10^-5 mL/mL phenylacetaldehyde, 1.0×10^-6 mL/mL Benzaldehyde, and 1.0×10^-5 and 1.0×10^-4 mL/mL salicylaldehyde showed significant attraction to both sexes of the fly. However, benzaldehyde, phenylacetaldehyde and salicylaldehyde at the concentration of 1.0×10^-3 mL/mL showed significant repelling effect against female and male adults. Cinnamyl alcohol and methyl salicylate at all four concentrations showed repelling effect against the males. Methyl salicylate could attract females at the concentration of 1.0×10^-6 mL/mL, but repel females at the concentrations from 1.0×10^-5 to 1.0×10^-3 mL/mL. Cinnamyl alcohol showed repelling effect against females at all concentrations. It revealed that these aromatics could attract adult flies at lower concentration but repel at higher concentration.
