6种蝗虫消化道的超微结构与食性相关性研究

Study on the Relationship between Digestive Tract Ultrastructure and Feeding Habits of Six Grasshoppers

  • 摘要: 运用生理解剖和电镜扫描技术,对隶属于3个科的6种蝗虫消化道的外部形态,前胃和贲门的内壁结构进行了研究.结果表明:消化道形态结构在科间存在差异,尤其体现在前胃和贲门内壁的超微结构上;6种蝗虫中,隶属于斑翅蝗科的黄胫小车蝗,其前胃和贲门都较其他种类更为发达,这与其是典型的多食性蝗虫相呼应;主要以菊科蒿属植物为食的斑腿蝗的短星翅蝗,在前胃内壁齿的着生方式、贲门内壁齿的尖端角度等方面均不同于其他5种以禾本科植物为食的蝗虫.虽然消化道形态结构在科间存在差异,但食性相似的隶属于不同科的蝗虫间消化道的结构是存在相似性的.由此可见,消化道形态结构的差异性与食性之间存在紧密联系,二者协同适应.

     

    Abstract: The external morphology of the digestive tract of six species of locusts belonging to 3 families, the structure of the inner wall of anterior stomach and cardia were studied by physiological anatomy and electron microscope scanning techniques. The results show that digestive tract morphological and structural differences were found between famlies, especially in the ultrastructure of the inner wall of the foregastric and cardia. The foregastric and cardia of the plantar locusts belonging to the family Pteroptera are more developed than other species, which is typical polyphagous locust. The short-winged locust of the family Catantopidae, which mainly feeds on sagebrush in Compositae, the attachment mode of teeth on the inner wall of the foregastric, the angle of the tip of teeth on the inner wall of cardia are different from the other five species, which feed on grasses. It shows that although the morphological structure of the digestive tract is different between families, the structure of the digestive tract between grasshoppers in different families with similar diets is similar. It can be seen that the differences in the morphological structure of the digestive tract are closely related to the diet and adapt to each other.
