对 Mamestra configurata 和 Trichoplusia ni 幼虫的帽状体外侧和内侧茎突感觉器中的化学感应细胞进行了电生理学研究。在每个物种的两个感器上测试了黑芥子苷、蔗糖、肌醇和氯化钾（KCl）。 T. ni 的外侧和内侧感器中的四个细胞之一对黑芥子苷敏感，而在 M, configurata 中，仅外侧感器中的一个细胞对黑芥子苷敏感。 T. ni 的外侧黑芥子苷敏感细胞比 M. configurata 的相应细胞敏感八倍。两个物种的侧感器中的一个细胞对蔗糖敏感。 M. configurata 的内侧感器含有肌醇敏感细胞，但 T. ni 中不存在对肌醇敏感的细胞。两个物种的外侧和内侧感器中的一个细胞对 KCl 敏感。给出了两个物种中黑芥子苷敏感细胞的适应和剂量反应数据。这些是在其他鳞翅目报道的威慑敏感细胞的背景下讨论的。考虑了比较生理学和进化方面，并讨论了鳞翅目威慑细胞的一般概念。
Chemosensory cells in the lateral and the medial styloconic sensillia on the galea of larval Mamestra configurata and Trichoplusia ni were investigated electrophysiologically. Sinigrin, sucrose, inositol and potassium chloride (KCl) were tested on both sensilla of each species. One of the four cells in both the lateral and medial sensilla of T. ni was sinigrin-sensitive, whereas in M, configurata, one cell in only the lateral sensillum was sinigrin-sensitive. The lateral sinigrin-sensitive cell of T. ni was eightfold more sensitive than the corresponding cell of M. configurata. One cell in the lateral sensillum of both species was sucrose-sensitive. The medial sensillum of M. configurata housed an inositol-sensitive cell but no cell sensitive to inositol was present in T. ni. One cell in the lateral and medial sensilla of both species was KCl-sensitive. Adaptation and dose-response data are given for the sinigrin-sensitive cells in both species. These are discussed in the context of deterrent-sensitive cells reported from other Lepidoptera. Comparative physiological and evolutionary aspects are considered and the general concepts of the lepidopteran deterrent cell is discussed.
