松叶蜂科昆虫的幼虫以针叶树的针叶为食(少数为害种实),常常造成相当严重的灾害,例如1979年云南省保山县董家山一带云南松发生祥云新松叶蜂为害面积达36000亩;云南省楚雄州南华县罗武庄和五顶山公社新松叶蜂大发生,1978年为害面积达27000亩、1982年达50000亩,1983年四川省西昌县云南松飞播幼林由于新松叶蜂为害成灾面积达10000余亩;1982年四川省金堂、蓬溪等20余县柏木种实为丽松叶蜂所害,致使种子大量减产。为了弄清我国松叶蜂的种类、分布及寄主植物,以便为研究其生物学及防治方法打下基础,现就已有标本及资料对我国松叶蜂从分类角度出发做一总的研究。共记述我国
For example, in 1979, Dongshan Mountain, Baoshan County, Yunnan Province, Yunnan pine occurred Xianfu new pine leaf bee damage area of 36000 Mu; Luwuzhuang, Nanhua County, Chuxiong Prefecture, Yunnan Province, and the New Pine Bumblebee, a commune of Wuding Mountain, occurred in 1978 with an area of 27,000 mu and an area of 50,000 mu in 1982. In 1983, Bees damage victimization area of more than 10000 acres; in 1982, Sichuan Province, Jintang, Pengxi and other more than 20 county cedar trees for the pine bough bee, causing a large number of seed production. In order to clarify the species, distribution and host plants of the pine needles in order to lay the foundation for the study of their biology and control methods, we now have specimens and data to do a total study on the classification of the pine needles from China. A total record of our country
