PROBLEM TO BE SOLVED: To provide a feed for wild silkworms by which wild silkworm cocoons can be obtained, which are high grade products, several times a year, and to provide a processing method therefor, a method for raising the wild silkworms and a method for producing the wild silkworm cocoons by using the feed for wild silkworms.SOLUTION: The problem is solved by a method for processing the feed for the wild silkworms that has: a step of putting tree leaves for the feed for the wild silkworms, such as collected Quercus acutissima and the like, and water into a container and freezing the same a step of bringing the frozen tree leaves into contact with boiling water or approximately boiling water at a temperature difference of 100°C or more and a step of preserving the contacted tree leaves after being dried. The method for raising the wild silkworms is to raise by feeding to larvae the feed for the wild silkworms returned by adding water to the tree leaves preserved by the processing method. The method of producing the wild silkworm cocoons is to raise the wild silkworms indoors or in a house using the feed for the wild silkworms and to produce cocoons twice or more a year.COPYRIGHT: (C)2016,JPO&INPIT【課題】高級品である天蚕繭を一年に数回得ることができるようにした天蚕用餌、その加工方法、及びその天蚕用餌を用いた天蚕の飼育方法及び天蚕繭の生産方法を提供する。【解決手段】採取したクヌギ等の天蚕用餌用樹葉と水とを容器に入れて冷凍する工程と、冷凍した前記樹葉と沸騰水又略沸騰水とを温度差100℃以上で接触させる工程と、接触させた前記樹葉を乾燥した後に保存する工程とを有する天蚕用餌の加工方法によって上記課題を解決する。天蚕の飼育方法は、その加工方法によって保存された樹葉に水を加えて戻した天蚕用餌を、幼虫に与えて飼育する方法である。天蚕繭の生産方法は、天蚕用餌を用いて天蚕を屋内又はハウス内で飼育し、年に2回以上の繭を製造する方法である。【選択図】図1
