Contact chemoreceptors on the mouthparts and legs of the blowfly Phormia regina that normally respond to aqueous solutions of sapid substances also respond to compounds in the gaseous state. Effective vapors include organic and inorganic acids and various unrelated nonpolar compounds. In general, the acids stimulate the salt receptor. Some nonpolar compounds stimulate the salt receptor while others inhibit it. Others stimulate the water, sugar, or "fifth" receptor. Differential action cannot be attributed to pH or solubility. Not all compounds that are irritating to mammalian mucous membranes or amphibian skin stimulate the contact chemoreceptors of the fly. Sensitivity to these vapors is a phenomenon analogous to the common chemical sense of vertebrates.
丽蝇(Phormia regina)口器和腿部的接触化学感受器通常对美味物质的水溶液有反应,现在也发现它们对气态化合物有反应。有效的蒸汽包括有机和无机酸以及各种不相关的非极性化合物。一般来说,酸会刺激盐感受器。一些非极性化合物刺激盐感受器,而另一些则抑制它。还有一些刺激水、糖或“第五”感受器。差异作用不能归因于pH值或溶解度。并非所有刺激哺乳动物黏膜或两栖动物皮肤的化合物都会刺激苍蝇的接触化学感受器。对这些蒸汽的敏感性是一种类似于脊椎动物普通化学感觉的现象。
