However,their populations have experienced different forms and levels of environmental pressure. This research aimedto verify the phenotypic plasticity in both size and shape of wings inA. melliferausing fluctuating asymmetry,based on geometric morphometrics from apiaries located in sites with high and low levels of anthropization.We sampled 16 locations throughout all five geographic regions of Brazil. At each site, samples were collectedfrom 20 beehives installed in apiaries: 10 installed near high anthropogenic environments (Cassilândia - MS,Fortaleza - CE, Maringá - PR, Aquidauana - MS, Rolim de Moura - RO, Riachuelo - SE, Ubiratã - PR andPiracicaba - SP), and 10 in sites with low levels of human disturbance (Cassilândia - MS, Itapiúna CE, Uniãoda Vitória - PR, Aquidauana - MS, Rolim de Moura - RO, Pacatuba - SE, Erval Seco - RS, Rio Claro - SP). Asample of 10 individuals was taken in each hive, totaling 200 per location, for a total of 1 600 individuals. Weused fluctuating asymmetry (FA) in size and shape of the forewing through geometric morphometrics. The FAanalysis was conducted in order to check bilateral differences. The indexes of size and shape were submittedto analysis of variance (ANOVA), where the characters evaluated were used as factors to verify the size andshape differences. The results indicated an asymmetry on the shape of the wing (P < 0.001) but no asymmetrywas observed on wing size. Considering FA as an environmental response and high and low impacted areasas a fixed factor, we observed significant differences (P < 0.05). The results for the wing shape inA. melliferademonstrated that this feature undergoes more variation during ontogeny compared to the variation in size. Weconcluded that bee samples collected from colonies with higher levels of human disturbance had higher wing-shape asymmetry; the variation of fluctuating asymmetry in the wing shape of honeybees can be used as an indi-cator of the degree of environmental anthropization.
