The genetic structure of natural populations of the economically important dipteran species Ceratitis capitata was analysed using both biochemical and molecular markers. This revealed considerable genetic variation in populations from different geographic regions. The nature of this variation suggests that the evolutionary history of the species involved the spread of individuals from the ancestral African populations through Europe and, more recently, to Latin America, Hawaii and Australia. The observed variation can be explained by various evolutionary forces acting differentially in the different geographic areas, including genetic drift, bottleneck effects, selection and gene flow. The analysis of the intrinsic variability of the medfly's genome and the genetic relationships among populations of this pest is a prerequisite for any control programme.
利用生化和分子标记分析了具有重要经济意义的双翅目物种地中海实蝇自然种群的遗传结构。这揭示了不同地理区域种群中存在相当大的遗传变异。这种变异的性质表明，该物种的进化历史涉及个体从非洲祖先种群扩散到欧洲，以及最近扩散到拉丁美洲、夏威夷和澳大利亚。观察到的变异可以用不同地理区域中不同作用的各种进化力量来解释，包括遗传漂变、瓶颈效应、选择和基因流动。对地中海实蝇基因组内在变异性以及该害虫种群间遗传关系的分析是任何控制计划的先决条件。
