| 摘 要： | 樗蚕（ＰｈｉｌｏｓａｍｉａｃｙｎｔｈｉａＷａｌｋｅｒｅｔＦｅｌｄｅｒ）在保定１ａ发生２～３代，以２代为主，以蛹在茧内于树上越冬。越冬代成虫羽化高峰期为５月８日，第１代成虫羽化高峰期为７月１６日。４龄幼虫排粪量为２６粒／头。４龄幼虫期平均抓着力为４２ｇ，５龄幼虫平均抓着力为１９５ｇ。樗蚕性比为雌∶雄＝１∶１０３。在河北省主要寄主植物有臭椿、臭檀、花椒、枣树、泡桐等，另外有１３种植物，共１８种，分别隶属于１６科。

| Abstract: | Ailanthus silkworms (Philosamia cynthia) have 2 or 3 generations,most of them have 2 generations,in Baoding.They overwinter with pupa in cocoon on trees.The peak period of emergence of the overwintered generation is on May 8,and that of the first generation is on July 16.A fourth instar larva can excretes 26 grains of excrements.The average clutching power of the larva is 42g,and that of fifth instar larva is 195g.The sex ratio of the insects is 1103.There are 18 species of plants including Ailanthus altissima,Evodia daniellii,Zonthoxylum bungeanum, etc,are damaged by this insect in Hebei. |
