Seven species of carabid beetles were examined in different "pH-Orgeln" for pH-preferences. Five of these species showed significant preferences for specific pH-fields. Presumably, this parameter of distribution found in the laboratory is also effective in the field. We caught the beetles in the field on soil of the same pH-values which they prefered in the laboratory. The pH-measurements taken by previous workers in the field match our results.The receptors for H-ions are probably located on the antennae, because the preference distribution of Pt. angustatus changed into a uniform distribution after amputation of the distal segments of the antennae. The structure of these receptors could not be identified in electron microscope pictures (REM) among the multitude of different receptors on the antennae.
研究人员在不同的“pH 培养皿”中检测了七种步甲科甲虫对 pH 值的偏好。其中五种甲虫对特定的 pH 范围表现出明显的偏好。据推测，在实验室中发现的这种分布参数在野外环境中同样有效。我们在野外捕捉到了这些甲虫，它们所处土壤的 pH 值与它们在实验室中偏好的 pH 值相同。之前研究人员在野外进行的 pH 测量结果与我们的一致。氢离子受体可能位于触角上，因为在切除触角远端节段后，狭翅步甲的偏好分布变成了均匀分布。在电子显微镜照片（REM）中，在触角上众多不同的受体中无法识别出这些受体的结构。
