Abstract究了木瓜榕(Ficus auriculata Loureiro)、苹果榕(F.oligodon Miquel)及未知榕(Ficus sp.)3种榕树传粉榕小蜂的核型。结果表明:3种榕树对应的传粉榕小蜂具有非常相似的核型,染色体数目相同为2n=10,染色体全部为中着丝粒染色体;核型公式2n=2X=10=10M,核型均为Stebbins-1A型。以臂比不对称性系数Dc和相对长度不对称性系数Dt作二维散点图,Ceratosolen emarginatus Mayr(木瓜榕传粉榕小蜂)和C.emarginatus Mayr(苹果榕传粉榕小蜂)具有非常相近的核型不对称系数,核型不对称性大于Ceratosolen sp.(未知榕传粉榕小蜂),显示出两者更近的亲缘关系,而Ceratosolen sp.(未知榕)与前两者亲缘关系较远。此外,比较了Ceratosolen属和Blastophaga属在核型方面的差异,认为染色体数目包括染色体形态能够作为准确区分Ceratosolen属和Blastophaga属的依据,并对Ceratosolen属的核型进化进行了初步探讨。
