This paper describes the esterase patterns found in a wild strain of Culex quinquefasciatus which was known to bear resistance genes and the existence of genetic polymorphism for such esterases is demonstrated. The most frequent polymorphisms found were Est-1, Est-2, and Est-3; Est-2 was possibly responsible for Culex quinquefasciatus resistance. The frequency of potentially resistant females was significantly higher as compared to males: in addition, the hypothesis was proposed that heterozygotie Est-3 is selected as a genotype which may contribute to resistance in neotropical areas.
本文描述了在已知携带抗性基因的致倦库蚊野生品系中发现的酯酶模式,并证明了此类酯酶存在遗传多态性。发现最常见的多态性是Est-1、Est-2和Est-3;Est-2可能与致倦库蚊的抗性有关。与雄性相比,潜在抗性雌性的频率显著更高:此外,有人提出假说,杂合子Est-3被选择为一种可能有助于新热带地区抗性的基因型。
