The successful distribution of A. mellifera is due to their ability adjust seasonal variations, considerable control over internal physical environment and exploration different resources. However, populations have experienced forms levels environmental pressure. This research aimed verify the phenotypic plasticity in both size shape wings using fluctuating asymmetry, based on geometric morphometrics from apiaries located sites with high low anthropization. We sampled 16 locations throughout all five geographic regions Brazil. At each site, samples were collected 20 beehives installed apiaries: 10 near anthropogenic environments (Cassilandia - MS, Fortaleza CE, Maringá PR, Aquidauana Rolim de Moura RO, Riachuelo SE, Ubiratã PR Piracicaba SP), human disturbance (Cassilândia Itapiúna União da Vitória Pacatuba Erval Seco RS, Rio Claro SP). A sample individuals was taken hive, totaling 200 per location, for a total 1,600 individuals. used asymmetry (FA) forewing through morphometrics. FA analysis conducted order check bilateral differences. indexes submitted variance (ANOVA), where characters evaluated as factors results indicated an wing (P < 0.001) but no observed size. Considering response impacted areas fixed factor, we significant differences 0.05). demonstrated that this feature undergoes more variation during ontogeny compared concluded bee colonies higher had wing-shape asymmetry; honeybees can be indicator degree
