Selective use of spatial information in insect visual navigation

亚社会性蝽，Parastrachia japonensis运输宿主核果到其若虫在木材中的洞穴。在机动过程中，利用林冠间隙作为路径积分的罗盘参考，监测目标的方位信息，但这种定位系统存在严重的问题。复眼的尾侧缺少小眼，因此，该虫的背部有一个盲区。即使在实验性的竞技场中，只有一个人造的圆形缝隙进入盲区，这种虫子也能完成往返飞行。然而，当盲间隙和非盲间隙都存在时，错误可以选择性地使用非盲间隙。因此，我想强调的是，空间信息的选择性使用受到昆虫导航员感觉器官结构限制的影响。

Subsocial stinkbug, Parastrachia japonensis transports host drupes to its nymph-containing burrow in a wood. In the provisioning excursion, it uses canopy gap for compass reference in its path integration to monitor the directional information, but it has serious problems on this orientation system. The compound eye lacks ommatidia on the caudal side, therefore, the bug has a blind area to its back. The bug could perform the round trip even in an experimental arena with only an artificial round gap entering the blind area. However, when both blind and no-blind gaps were presented, bugs could selectively use a no-blind gap. Thus, I would like to emphasize that the selective use of the spatial information is influenced by the structural limitation of sensory organ of the insect navigators.
