Strong sexual isolation established between D. melanogaster long-term cage populations (originated from common parents and being under selection pressure since 1972) is maintained (with a tendency to increase) for twelve years after the origin of the populations. The sexual isolation is also maintained when the populations are kept in common conditions for about two years, while it dramatically decreases when the populations live on a food medium supplemented with strong chemical selective factors, such as various metals or ethanol. Seasonal or geographical studies of sexual isolation between natural and our cage populations did not reveal significant deviation from random matings. The genetic nature of sexual isolation is discussed.
在黑腹果蝇长期笼养种群（源自共同亲本且自1972年以来一直处于选择压力之下）之间建立的强烈性隔离，在种群起源后的十二年里得以维持（并有增加的趋势）。当种群在共同条件下饲养约两年时，性隔离也能维持，而当种群生活在添加了强化学选择因子（如各种金属或乙醇）的食物培养基上时，性隔离会显著降低。对自然种群和我们的笼养种群之间性隔离的季节性或地理性研究未发现与随机交配有显著偏差。本文讨论了性隔离的遗传本质。
