| 摘 要： | 通过比较不同生境油茶林区油茶史氏叶蜂幼虫危害程度、同一种生境距林边不同距离油茶史氏叶蜂的危害程度,分析了油茶史氏叶蜂对油茶春梢发育、夏梢发育、花芽分化率、花芽数目、落果率等的影响。结果表明:油茶史氏叶蜂对油茶的春梢发育、夏梢发育、花芽分化率、春梢上花芽数目、同期的落果率等有显著危害,且危害程度和林区的生态多样性相关;不同生境下,生态多样性越低,危害越严重;同一生境下,距混合林区距离越远,危害程度越重,说明保护油茶林区及周边生境的生态多样性,对防治和控制油茶史氏叶蜂是必要的。另外通过间接证据,提出了白头鹎Pycnonotus sinensis和伯劳Lanius schach等食虫鸟类是油茶史氏叶蜂幼虫重要捕食性天敌的初步结论。

| Abstract: | We compared the damage degrees of larvae of D.camellia to camellia forest in different habitats and different distances to woodside in the same habitat.The results show that the larvae of D.camellia are significantly harmful to the growth of spring shoots and summer shoots,and would reduce the flower bud differentiation rate,the number of flower buds and the fruit drop rate.The degree of harmfulness was related to ecological diversity of the camellia forest,in different habitats,the lower ecological diversi... |
