Sažetak
Compared to other fruit fly species the Mediterranean fruit fly or medfly, Ceratitis capitata (Wiedemann) is the most important fruit fly due to its ability to survive adverse and often unfavorable conditions. It is highly polyphagous since it inhabits over 200 plants species. Medfly is quarantine pest in Croatia (A2 list). It feeds on soft and juicy fruits such as mandarin and other citrus fruits, peach, apricot, pear, apple, etc. Damage caused by this pest is severe. Tissue around oviposition injection spot changes color, spot expands over few days and tissue beneath begins to rot causing a dent on the surface. Such fruit is completely unusable and has no market value. Damages are highest in summer and autumn. Agroecological factors such as soil structure, soil pH, weather conditions and suppression measures contribute to morphological variability of medfly. Morphological variation can affect species ability to spread and adjust to new areas. Geometric morphometric procedures are valuable tools for evaluating levels of phenotypic changes influenced by genetic changes. Such procedures were used in this survey in order to estimate influence of biotic (suppression and cultivation measures) and abiotic factors (weather conditions, soil) on medfly's wing size and shape. Based on different phenotypes we investigated the impact of change in medfly wings on its ability to expand into new areas. Morphology of medfly's wings has been analyzed by standard geometric morphometric procedure based on location of 14 markers placed on insect's wing veins. This innovative and effective but yet simple and cheap method establishes differences in wings shapes and sizes allowing us to use those differences as biomarkers of inter and intra-population variation. Implication of this experiment suggests that geometric morphometric procedures can be used for population research with contribution to research of biological adaptation of medfly.
