摘　　要：为明确华北大黑鳃金龟Holotrichia oblita(Faldermann)的嗜食植物,优化其室内人工饲养技术及为诱虫植物提供候选材料,以花生叶片为对照,研究了7种林木植物叶片对华北大黑鳃金龟取食和繁殖的影响。结果表明,华北大黑鳃金龟对8种植物日均取食量由高到低依次为金叶女贞、刺槐、核桃、榆树、花生、柳树、香椿、毛白杨,其中金叶女贞、香椿和毛白杨与花生间有极显著差异,金叶女贞与刺槐、核桃、榆树间无显著差异;单雌产卵量由高到低依次为金叶女贞、柳树、核桃、香椿、花生、榆树、毛白杨、刺槐,其中金叶女贞、柳树、核桃、刺槐与花生间有极显著差异,而金叶女贞与柳树间无显著差异。研究表明,饲养华北大黑鳃金龟成虫适宜饲料植物为金叶女贞,日均取食量最高为4.70 g,产卵期最长为56.00 d,单雌产卵量最多为58.88个,其次为核桃和柳树。To clarify the feeding preferences of Holotrichia oblita（ Faldermann）,improve the indoor artificial breeding technology and provide materials for the trap plants,the influences of seven species of forest plants on feeding and fecundity of H. oblita with Arachis hypogaea L. as control were studied. The results showed that the average daily consumption of H. oblita to the leaves of the eight species plants were as followed： Ligustrumx vicaryi, Robinia pseucdoacacia, Juglans regia, Ulmus pumila, A.hypogaea,Salix matsudana,Toona sinensis and Populus tomentosa,in descending order. L. vicaryi,T.sinensis,P. tomentosa showed highly significant difference from the control,but the difference between R. pseucdoacacia,J. regia and U. pumila was not significant. The ovoposition per female of H. oblita were as followed： L. vicaryi,S. matsudana,J. regia,T. sinensis,A. hypogaea,U. pumila,P.tomentosa and R. pseucdoacacia,in descending order. L. vicaryi,S. matsudana,J. regia and R.pseucdoacacia showed highly significant difference from the control A. hypogaea,while S. matsudana had no highly significant difference from L. vicaryi. The results indicated that the leaves of L. vicaryi was the suitable feeding plant for H. oblita adults,slightly better than J. regia and S. matsudana,with a highest average daily consumption of 4. 70 g,a longest spawning period of 56. 00 d and a maximum fecundity per female of 58. 88.
