A pair of receptors, responding tonically to pressure applied internally, occurs on the ventral body wall of abdominal segments two to five in the adult of the blood-feeding insect, Rhodnius prolixus. These receptors are located in a region of the body wall subject to forces directly related to the size and movement of the stomach, an enlarged region of the midgut which stores the blood meal, and are therefore well suited for monitoring the degree of distension there. The initiation of many endocrinological processes in Rhodnius is known to be associated with the detection, over a period of several days, of abdominal distension, and these sensory receptors are capable of responding to abdominal distension for extended periods of time.
一对受体在吸血昆虫 R. prolixus 的成年个体的第二至第五腹节的腹壁上，对内压呈紧张性反应。这些受体位于一个与胃的大小和运动直接相关的体壁区域，胃是中肠的一个扩大区域，储存着血液餐，因此非常适合监测那里的膨胀程度。Rhodnius 中的许多内分泌过程的启动被认为与对腹部膨胀的检测有关，这个过程持续几天，这些感觉受体能够对腹部膨胀做出长时间的反应。
