北京地区黄栌胫跳甲的危害情况与综合治理

Harm of Beijing Area Ophrida xanthospilota and Comprehensive Management

对北京的香山公园、百望山森林公园、西山林场、密云水库以及山东的红叶谷景区、石门坊等地黄栌胫跳甲的危害情况、生活习性进行调查,同时在北京地区进行综合防治试验。结果表明,北京地区发生率明显高于山东地区,且黄栌分布的区域均有黄栌胫跳甲为害,严重时会造成黄栌叶片缺刻、损伤甚至只剩叶柄,严重影响黄栌的正常生长和秋季观赏效果。黄栌胫跳甲的发生情况与生境因素和气候因子有明显关系,同时化学药剂和人工修剪等方式对其有明显防治效果,采用苦参碱1 500倍稀释液、杀苏水剂1 500倍稀释液、木烟碱3 000倍稀释液、桉油精1 200倍稀释液和除虫脲2 000倍稀释液喷洒黄栌树冠,对幼虫的防效可达96%以上。

Through researching on Beijing Fragrant Hill Park,Baiwangshan Forest Park,West Hill Forest,Miyun Reservoir,compare the situation of Ophrida xanthospilota damage and life habit with Shandong red leaves valley scenic area,Shimenfang and etc,and do comprehensive control and prevention experiment in Beijing area at the same time. Result shows that： the incidence was significantly higher in Beijing area than that in Shandong Province,and Ophrida xanthospilota exist in every Cotinus coggygria distribution region,seriously cause cotinus leaves incised,damage,or only leave over petiole,great affect the normal growth and autumn ornamental effect of Cotinus coggygria. Occurrence of flea beetle is significantly related to environmental factors and climatic factors. At the same time,chemicals,artificial pruning and other methods prevention have obvious treatment effect. The Matrine of 1 500 times fluid,killing Su agent 1 500 times fluid,wood nicotine 3 000 times liquid,eucalyptol1 200 times fluid and diflubenzuron 2 000 times liquid,spray the canopy,the rate of preventing the larvae will be above 96%.
