The Mediterranean fruit fly or medfly, Ceratitis capitata (Wiedemann, 1824) is one of the most economically important fruit flies globally. Geometric morphometric methods based on principal component analyses, multivariate regressions and two blocks partial least squares analyses were used in this study to estimate patterns of sexual shape dimorphism and the influence of agroecological factors (weather conditions, soil properties) in two different populations on C. capitata in Croatia. Results shown significant differences in mean shape between C. capitata sexes, nevertheless, females did not modify they wing morphology between populations, in contrast to males where the wing shape differ between island and continent populations. Wing size and shape showed particularly differences between agroecological systems suggesting metapopulation structure of C. capitata which is currently favouring sex-specific plasticity. These results show that geometric morphometric procedures can be used to provide key insight into the biological adaptation of medfly in newly invaded habitats, a significant process that ensures invasion success.

地中海果蝇或地中海果蝇（Ceratitis capitata，Wiedemann，1824年）是全球经济上最重要的果蝇之一。本研究使用基于主成分分析，多元回归和两个区块偏最小二乘分析的几何形态计量学方法估算了两个不同种群的性状二态性模式以及农业生态因素（天气条件，土壤性质）对C的影响。卡塔塔在克罗地亚。结果显示，C。capitata的平均形状存在显着差异但是，雌性并未改变种群之间的翅膀形态，而雄性则在岛屿和大陆种群之间改变了翅膀的形状。翼的尺寸和形状显示农业生态系统提示的集合种群结构之间的差异尤其实蝇这是目前有利于性别特异性可塑性。这些结果表明，几何形态计量学程序可用于提供对新入侵的栖息地中墨蝇生物学适应的关键见解，这是确保入侵成功的重要过程。
