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.
在脊椎动物中，已有研究表明双眼视觉体验对于发展正常的空间视觉是必要的。我们研究了这对于一种无脊椎动物——螳螂来说是否同样如此。螳螂是一种捕食性昆虫，其猎物定位涉及双眼视差的运用。我们饲养了在整个发育过程中一只眼睛被遮挡的螳螂，并测试了成年动物的单眼视觉注视和双眼距离估计。结果显示，在单眼饲养的动物中，注视和捕食行为功能均正常。因此我们得出结论，对于螳螂来说，双眼视觉基于一种固定的发育模式。
