用扫描电镜观察了德国小蠊下颚须的超微结构。结果表明，德国小蠊下颚须分为５节，第１、２节较短，第３～５节较长。雌虫第１～４节有鳞片，第５节无鳞片，雄虫第１～５节均有鳞片。第３节内侧端１／５处有１椭圆形凹陷，内有乳突状突起。第４节末端内侧有１凹陷，内有许多锥形感器。第５节内侧有大、小两个凹陷区，底部有许多带槽锥形感器，侧壁有许多不规则锥形感器和少量刺形感器Ｂ。在５个节段上均有刺形感器Ｂ。刺形感器Ｃ和帽状感器分布于第５节。
The ultrastructure of the jaw of German cockroach was observed by scanning electron microscopy. The results showed that the German cockroach jaw should be divided into five sections, Section 1, 2 short, Section 3 to 5 longer. Females 1 to 4 with scales, the first 5 sections without scales, males have scales 1 to 5. Section 3 medial end 1/5 at an oval depression, papillae-like protrusions. There is a depression on the medial side of section 4, with many conical sensors inside. Section 5 inside the large and small two recessed area, the bottom of the groove with a tapered sensor, the side wall has a lot of irregular pyramidal sensors and a few thorns B. Barbed sensors on both segments. Thorn sensors C and cap sensors are located in Section 5.
