摘要
日本松干蚧于20世纪90年代初期传入日照市,对松林造成严重危害,赤松濒临灭绝。为更好开展科学防治,从2000年开始对该虫进行系统虫情调查,通过设立固定标准地,对日本松干蚧越冬代和越夏代各虫态进行系统观测,确定了其在日照地区的生活历,填补了日本松干蚧发生发展规律在该地域的空白,对指导该地区开展科学防治具有重要意义。
Matsucoccus matsumurae invaded Rizhao in early 1990＇s, which was very harmful to pine woods with the result that Pinus densiflora forest was on the verge of extinction. To control it more scientifically, systematic survey and observation on every stage of over-wintering and over-summering Matsucoccus nzatsunzurae in stationary plots have been made since 2000 to determine its life cycle in Rizhao area. It filled in the blank of its occurrence and development regularity in this area, which was important for guiding its scientific control.
