鲎(háo)Triops spp 是属于鳃脚亚纲 Branhiopoda 背甲目 Notostraca 的淡水甲壳类动物。现在局部地区如大坂府河内,长野市等地用它除治水田杂草。但普及速度慢,其原因是防治效果不如除草剂稳定,且人们对这种动物认识不足。由秋田、片山等研究了鲎的生理生态学方面的问题,及其除草机理和除草效果,取得了一些成果。一、关于鲎的生活习性在日本分布有 T·riops caniformis(欧洲种)、T·granarius(亚洲种)、T·logicaudatus(美洲种)三种。欧洲鲎只分布在山形县酒田市一带,亚洲鲎和美洲鲎则分布在关东至北九洲各地。有的同
Triops spp is a freshwater crustacean belonging to the Branhiopoda family, Notostraca. Now some areas such as Osaka Hanoi, Nagano and other places use it in addition to paddy field weeds. However, the spread is slow because the control effect is not as stable as herbicides, and people do not know enough about this kind of animal. From Akita, Katayama and other studies on the physiological and ecological problems, and its weeding mechanism and weeding effect, and achieved some results. First, on the living habits of the Japanese distribution in T riops caniformis (European species), T granarius (Asian species), T logicaudatus (American species) three. Europe 鲎 is only distributed in the vicinity of Sakata City in Yamagata Prefecture, while 鲎 and 美 in Asia are distributed throughout Kanto and Kitakyushu. Some of the same
