Sažetak
Geometric morphometrics was used to analyze codling moth population variability in integrated and ecological systems of apple production in Croatia. The aim of study was to investigate the connection between different pest management types and C. pomonella morphology. Altogether, ten field populations (six from integrated and four from ecological apple production) and one laboratory grown population, which has never been exposed to insecticides, were sampled. The wing morphology of 294 C. pomonella were investigated using standard geometric morphometric procedures based on the forewing venation of 18 landmarks. Data analysis was divided into two groups: 1) field populations versus laboratory population ; and 2) integrated versus ecological populations. The results demonstrated a morphological difference in field populations versus laboratory population and integrated versus ecological populations. This study presents an affordable and accessible technique that reliably demonstrates wing shape and size differences which can be used to reveal populations differences and thus can be used as a biomarker. Overall implications from this work suggest that geometric morphometric techniques can be used to detect population changes of apple production and could serve as alternative ‘biomarker’ to more expensive and specialized-use genetic markers, when investigating biological adjustments.
