| 摘 要： | １９９４年以来，靖远松叶蜂在关帝山林局的油松林内猖獗为害，以幼虫取食油松２年生以上针叶，该虫一年１代，以茧内预蛹越冬。７月上中旬为孵孵化盛期，幼虫蜕 皮４次－５次。１０月下旬老熟幼虫下树，在树冠投影范围内的地被物下结茧越冬。该虫的发生及危害，阴坡大于阳坡，纯林大于混交林。在山高林密、交通不便、害虫发生面积大而集中连片，且蔓延速度快的情况下，宜采用飞机喷药防治法。飞防时间在关帝山为８月中旬。每一架次

| Abstract: | Since 1994,the Diprion jingyuanensis has damaged rampantly the Chinese pine forest in Guandi mountain.The larve took the 2 year and over of needles as thier food,and all the needles on a tree could be eaten off.The insect was 1 generation a year in Guandi forest district,overwintering as prepupa in cocoon.It was the adult's major emergence period in the last ten days of June,and incubation period of the ovum in the first 20 days of July.Ecdysis of the larva 4 to 5 times.In the last ten days of Oct.,mature larve got down the tree along the stem,spinning cocoon and overwintering in the ground cover in the range of crown projection.The occurrence and damage degree of the insect on shady slopes was more serious than that on sunny slopes,and in pure forests was more serious than in mixed forests.In the case of high hills,dense forest,and no transport facilities where the insect occurred,large and concentrative area of insect occurring,and fast spreading of the damage,it is suitable to control with aerial spraying.The middle of Aug.is the rational date for air spraying control.A plane on time with 60 kg of fenvalarate,50 kg of fine salt,and 690 kg of water can achive 120 hm 2 of air control area.In our works,the air control area of the three forest farms,Baihuling,Sandaochuan,and Shuangjiazhai totalled 23 2 thousand hm 2 ,the control effect was 87% and over. |
