摘　　要：黄点直缘跳甲Ophrida xanthospilota Baly是危害黄栌Cotinus coggygria的主要害虫,造成黄栌叶片缺刻、损伤、甚至只剩叶柄,严重影响黄栌正常生长和秋季观赏效果。通过人工饲养从香山公园、百望山森林公园、西山林场、密云水库等地黄栌林采集的黄点直缘跳甲卵块、幼虫,开展寄生天敌分离、繁育试验,发现跳甲异赤眼蜂Asynacta ophriolae Lin,1993和卵跳小蜂属Ooencyrtus Ashmead一新种Ooencyrtus sp.共2种卵期寄生性天敌,寄生蜂出蜂量与卵块数线性相关。Ophrida xanthospilota Baly is one of the most serious pests affecting the growth and ornamental value of Cotinus coggygria.Egg masses and larvae of the pest collected from C.coggygria forests in Xiangshan Park,Baiwangshan Forest Park,Xishan Forest Farm and Miyun Reservoir were artificially reared and two egg parasitoids：Asynacta ophriolae Lin and Ooencyrtus sp.,a new species of Ooencyrtus Ashmead,were found from the egg masses.A linear correlation was found between the parasitoids and egg masses.
