摘　　要： 应用聚丙烯酰胺凝胶电泳技术研究了秦岭4种缘蝽的EST同工酶。研究结果表明,姬缘蝽亚科2属间差异要大于属内各种间差异。控制开环缘蝽及点蜂缘蝽的EST位点分别为4和5个,而且乙酸萘酯为底物的酯酶除未发现杂合子而无法确定的以外,都是单体酶,不同个体间酶谱差异主要是同一位点来自父母本的2个等位基因的不同而造成的,雌雄差异可能由性连锁基因引起。点蜂缘蝽3个居群等位基因频率存在差异,还需要进一步试验研究。 This paper deals with the esterase isozymes of four species of subfamily Rhopaline and Alydinae（Hemiptera ：Coreidae） in Qinling Mountainous region by the vertical slab poiyacrylamide gel electrophoretic technique. The variances between the two genera of Rhopalinae are obvious than intraspecific differences. There are 4 and 5 loci resolved for Stictopleurus minutus and Riptortus pedestris, respectively. All the esterase present as monomeric enzyme except for these which were dominated by monomorphic loci. The isozyme polymorphism of individuals within a Coreidae species is results from the pair of different alleles at the same loci. And sex-linked gene may result in the difference between female and male within species. Differences in allic among three populations of R. pedestric appeared, but the data available is limited and calls for further research.
