尖突水龟虫形态结构的观察

摘要

Hydrophilus acuminatus Motschulsky from Nenjiang River were dissected for morphological observations with anatomical lens, magnifying glass, and microscope. Functions of the main body parts, including head, thorax, abdomen and their adnexa, as well as the body systems, including digestive system, respiratory system, reproductive system, circulatory system, excretory system and muscular system, were discussed aiming to provide scientific materials for further studies on development and utilization of water scavenger beetles. However, it needs more experimental confirmations on the structure and functions of the nervous system.%利用解剖镜、放大镜、显微镜等对野外嫩江水域的尖突永龟虫头部及附器、胸部及附器、腹部及附器以及内部的消化系统、呼吸系统、生殖系统、循环系统、排泄系统、肌内系统的形态结构进行了观察研究,并阐述了各结构的功能.
