The anatomical organization of distinct regions in the insect brain often reflects their functions. In the present study, the brain structure of Apolygus lucorum was examined by using immunolabeling and three-dimensional reconstruction. The results revealed the location and volume of prominent neuropils, such as the antennal lobes (AL), optic lobes (OL), anterior optic tubercles (AOTU), central body (CB), lateral accessory lobes (LAL), mushroom lobes, and distinct tritocerebral neuropils. As expected, this brain is similar to that of other insects. One exception, however, is that the antennal lobes were found to be the most prominent neuropils. Their size relative to the entire brain is the largest among all insect species studied so far. In contrast, the calyx, a region getting direct input from the antennal lobe, has a smaller size relative to the brain than that of other species. These findings may suggest that olfaction plays an essential role for A. lucorum.

猪poly脑组织:具有突出的触角叶的半翅目物种。

昆虫脑中不同区域的解剖结构通常反映了它们的功能。在本研究中,通过免疫标记和三维重建检查了lu肉的大脑结构。结果显示了突出的神经毛的位置和体积,例如触角叶(AL),视神经叶(OL),前视神经结节(AOTU),中心体(CB),侧副叶(LAL),蘑菇叶和独特的三脑神经纤维。不出所料,该大脑类似于其他昆虫的大脑。但是,一个例外是,发现触角叶是最突出的神经毛。迄今为止,它们相对于整个大脑的大小是所有昆虫物种中最大的。相反,花萼是从触角叶直接输入的区域,相对于大脑而言,它的大小要小于其他物种。这些发现可能暗示嗅觉对A. lucorum起着至关重要的作用。
