摘要
油松球果瘿蚊(Cecidomyiaweni)Jiang严重危害油松(Pinustabulaeformis)Car.一年生小球果,并可在雄球花序上取食;该虫在辽宁兴城一年发生二代,以蛹在地表越冬。发现其蛹寄生蜂天敌3种,其中中国新记录属新种1种:球果瘿蚊短喙金小蜂(Capeliaconi)Yang。越冬代油松球果瘿蚊蛹总寄生率可达209%。拟除虫菊酯类和有机磷类药剂均对杀灭其成虫有效,可降低一年生球果受害率44%~56%。
Cecidomyia weni Jiang was firstly found in a Pinus tabulaeformis Carr. seed orchard in Xingcheng, Liaoning Province in 1987. It is bivoltine. The larvae mainly feed on the first year cones causing serious injury. Male inflorescences also can be damaged. Its larvae drop to the ground and pupate, then overwinter in cocoons in the litter. At least three species of parasitic natural enemy are found, including Capellia coni Yang, pyrethroid and phosphoramidate are effective to control the adult of C.weni Jiang.
