摘要。从Schistocerca gregaria在第三或第四龄早期去除触角导致第五龄幼虫具有绿色血淋巴和角质层。与对照昆虫相比，切除触角的成虫具有较低的体干重和较小的脂肪体。此外，它们的性发育速度增加，它们的一些形态参数发生了改变。将咽侧体植入四龄幼虫体内，几天后血淋巴呈绿色。这表明，触角切的血吸虫成虫allatum激素的有效性增加，其伴随的影响若虫色素沉着，生长和发育，和成人形态。有人进一步建议，密集蝗虫的触角切除术可能会模仿，对他们来说，不拥挤的条件下，通过减少感官输入。
ABSTRACT. Removal of the antennae from Schistocerca gregaria early in the third or fourth instar resulted in fifth instar nymphs with a green haemolymph and cuticle. Antennectomized adults had a lower somatic dry weight and a smaller fat body than operated control insects. In addition, their rate of sexual development increased and some of their morphometric parameters were altered. Implantation of corpora allata into fourth instar nymphs induced a green coloration of the haemolymph after a few days. It is suggested that antennectomy of Schistocerca nymphs resulted in an increased effectiveness of the corpus allatum hormone with its concomitant effects on nymphal pigmentation, growth and development, and adult morphometries. It is further suggested that antennectomy of crowded locusts may mimic, for them, the uncrowded condition, by reducing sensory input.
