abstract
Fluctuating asymmetry (FA) measures deviations from the ideal state of symmetry, a common tool that measure environmental and genetic stresses experienced by individuals or population that affect their morphology during development. It had been used to show how developmentally stable an individual is. This study was made to evaluate developmental stability by measuring fluctuating asymmetry in the wings of Ae. albopictus from three different breeding sites (Tipanoy, Del Carmen, Tambacan). This is to understand the nature and variation of Ae. albopictus found in Iligan City. Only female adults (N=60) per site were utilized in this study. FA levels of samples from each site were measured for comparison. In this study, anatomical landmarks were subjected to Procrustes superimposition and Principal component analysis (PCA) using “Symmetry and Asymmetry in Geometric Data‟ (SAGE) program. Results yield highly significant FA in the wings of Ae. albopictus collected in the three barangays. Results implied that species populations present in the three areas can be considered as developmentally unstable.
