日本松干蚧Matsuccccus matsumurae Kuwana是国内重要森林病虫检疫对象,60—70年代,该虫曾在辽东半岛和山东半岛地区大面积暴发成灾,70年代中期,分别在宁—沪—杭铁路沿线松林内发现,南京及近郊地区仅在中山陵园,江宁县东善桥林场的牛首和东善两分场有发生,此外,在溧阳县龙潭林场和南通市狼山风景点也有此虫为害。 1986年9月,我们在溧水县林场西横山分场雨山22小林班发现日本松干蚧雌雄成虫及寄生蚧;1987年3月上旬在该地又采到1—2龄寄生蚧,4月初调查,发生面积约60亩(该松林为20年生以上,树高10米左右,胸径10—20厘米)。1987年10—11月调查,发生面积80亩以上,1988年4—5月调查,该虫在雨山林区发生面积超过100亩,受害树开始弯枝下垂。值得注意的是在距雨山3公里外的朱村林班龙坳25小林班又有显露蚧被发现。
Matsucccus matsumurae Kuwana is one of the most important forest pest and disease quarantine objects in the country.
