摘要在脊椎动物中，已经证明双眼视觉经验对于发展正常的空间视觉是必要的。我们已经研究过这种情况是否也适用于一种无脊椎动物，螳螂。螳螂是一种捕食性昆虫，其中猎物定位涉及使用双眼视差。我们提出了螳螂，其中有一只眼睛闭塞在整个发展和测试单眼视觉固定和双眼距离估计成年动物。结果表明，在单眼饲养的动物中，固定和捕食行为都是正常的。因此，我们得出结论，在螳螂，双眼视觉是基于一个固定的发展模式。
Abstract In vertebrates, it has been shown that binocular visual experience is necessary to develop normal spatial vision. We have investigated whether this is also true for an invertebrate, the praying mantis. The praying mantis is a predatory insect in which prey localization involves the use of binocular disparities. We raised mantids which had one eye occluded throughout development and tested monocular visual fixation and binocular distance estimation in the adult animals. The results revealed that both fixation and prey catching behavior were normally functional in the monocularly reared animals. Thus we conclude that, in mantids, binocular vision is based on a fixed mode of development.
