中华稻蝗人工饲养技术初探

Preliminary Studies on Artificial Rearing Technique of Chinese Rice Grasshopper Oxya chinensis(Thunberg)

根据中国林蛙取食的特点 ,提出以中华稻蝗替代或部分替代黄粉虫作为中国林蛙饵料的设想 ,并对其人工饲养技术进行了初步研究。试验结果表明3龄前饲以活体狗尾草优于水稻 ,而3龄后则相反。活体植株饲养累积死亡率呈S型 ,而剪叶饲养的累积死亡率呈J型。

According to the preying habit of Chinese forest frog, this article gave an idea to feed it with Chinese rice grasshopper as a substitute food or at least a part, and preliminary studies were carried out on artificial rearing technique of Chinese rice grasshopper. The results indicated that the living bristlegrass was better than rice in feeding Chinese rice grasshopper before 3rd instar, but it was conversed for the subsequent instars. The accumulated mortality of Chinese rice grasshopper fed with living grass showed a 'S' shape with time, while it showed a'J'shape when fed with leaves. According to this study, we proposed to rear Chinese rice grasshopper with living bristlegrass befor 3rd instar outdoor and then with leaves in door.
