摘  要:对大叶榕榕果中寄生的非传粉小蜂Camarothorax bimasculinus进行显微观察与形态比较,结果表明该小蜂具有雄性多型现象,其雄蜂具有翅和无翅两种类型。有翅型雄蜂与雌蜂外形较相似,复眼发达,具翅两对,能够在榕果外与雌虫交配;无翅型雄蜂与雌蜂外形差异较大,复眼退化,无超,在榕果内与雌虫交配,存活寿命比有翅型雄蜂短。Through the observation by microscope and the morphological comparison of Camarothorax bimasculinus, a species of nonpollinating fig wasps hosted on Ficus virens var. sublanceolata, the male dimorphism of the species were found. The male wasps have two types: wings and no wings. The alate males are more similar with females, with well-developed compound eyes and two pairs of wings, mating with females inside or outside the fig. The apterous males are quite different from females, compound eye degeneration, wingless,mating with females inside the fig. The survival time of the Mate males are significantly longer than the apterous males.
