桃蛀野螟Diohocrocis punctiferalis Guen(?)e是一种分布广、食性杂的农、林、果害虫。我国、朝鲜、日本、大洋洲、南亚和东南亚都有分布。在浙江省长兴、金华、余杭和安吉县的马尾松林时有发生,而且有时成灾。 1982—1983年,我们对为害马尾松pinusmassoniana Lamb的桃蛀野螟进行了部分生物学观察,现就发现的一些问题提出讨论。 一、桃蛀野螟为害马尾松的特点 1.以老幼虫群聚松梢虫苞内越冬1982年4月下旬,1983年5月初,在金华和龙泉县观察和采集被害的马尾松松梢,发现幼虫并不蛀入 Peach borer Diohocrocis punctiferalis Guen (?) E is a wide distribution, eating habits of agricultural, forest, fruit pests. China, North Korea, Japan, Oceania, South Asia and Southeast Asia are distributed. The masson pine forests in Changxing, Jinhua, Yuhang and Anji counties of Zhejiang Province have occurred from time to time, sometimes with disasters. In 1982-1983, we conducted a partial biological observation of the pest moth (Pinus massoniana Lamb) that attacked Pinus massoniana Lamb. We will now discuss some of the problems identified. First, peach borer damage characteristics of Pinus massoniana 1 to the old larvae cluster pine Pinwort wintering in late April 1982, early May 1983, in Jinhua and Longquan County observed and collected victims of Pinus massoniana pine, Found larvae do not bite into
