The esterases of the cotton boll weevil were separated by polyacrylamide gel electrophoresis into four major regions. These were named Est I-IV in order of migration from anode to origin. Polymorphism was observed in all regions. The Est II region was shown to consist of no more than two bands (fast and slow). The inheritance of the fast and slow bands of Est II was demonstrated to be controlled by codominant autosomal alleles. Analysis of the gene frequency of the Est II region showed that one field population was consistent with the Hardy-Weinberg law (P = 0.995), while a second field population was not at equilibrium (P less than 0.001).
棉铃象甲的酯酶通过聚丙烯酰胺凝胶电泳被分离成四个主要区域。这些区域按照从阳极到原点的迁移顺序被命名为Est I-IV。在所有区域均观察到多态性。Est II区域显示由不超过两条带（快带和慢带）组成。Est II的快带和慢带的遗传被证明受共显性常染色体等位基因控制。对Est II区域的基因频率分析表明，一个田间种群符合哈迪-温伯格定律（P = 0.995），而另一个田间种群则处于非平衡状态（P小于0.001）。
