摘要
采取林间调查和室内饲养相结合的方法,对烟台地区栎空腔瘿蜂的形态特征和生物学特性进行了观察。结果表明:栎空腔瘿蜂在烟台1年发生2代,4—5月有性世代虫瘿在麻栎、栓皮栎雄花序上发生,6—9月无性世代虫瘿在叶片上发生。绝大多数以有性世代的卵在麻栎花芽内越冬,少数以无性世代幼虫或蛹在脱落于枯枝落叶层中的虫瘿里越冬。
Both field survey and laboratory rearing were used to observe and investigate the morphological and biological characteristics of Trichagalma acutissimaeon Quercus acutissima in Yantai.T.acutissimae has two generations per year,including the sexual generation and asexual generations.The sexual generation occurs on the male inflorescence from April to May,and the asexual generation occurs on the leaves from June to September.The most sexual generation overwinters within the flower buds on the stage of egg,while a few overwinters within galls that shed in the deciduous layer on the stage of asexual larvae or pupae.
