中文摘要: 室内人工大量继代饲养小菜蛾Plutella xylostella L.,是开展小菜蛾各种研究的基础。本文介绍用三月慢青菜萝卜苗法饲养小菜蛾的方法。在(24±1)℃、相对湿度60%~70%、光周期L∶D=14∶10条件下,小菜蛾能连续继代健康繁衍,卵的孵化率和蛹的羽化率可达90%以上。该方法简单实用,成本低,管理方便,可为室内生物测定工作提供发育基本一致的虫源。
英文摘要: Artificial rearing of the diamondback moth, Plutella xylostella L., has been the foundation of research on this species. When reared on green vegetables and white radish at a temperature of (24±1)℃, R.H. of 60%—70% and a photoperiod of L∶D=14∶10 hatching and the adult emergence rates can exceed 90%. This method is simple, practical and economical; a very convenient way to manage and supply insects for research.
