This study aimed to identify, through geometric morphometrics, a body structure that allows for a standardized study of the morphological variations and fluctuating asymmetry of V. destructor in different environmental contexts. To this end, we analyzed the morphology of mites infesting colonies of Africanized honeybees in two contexts: different levels of hygienic behavior in the colonies and distinct environments (Caatinga and Atlantic Forest). Asymmetry is specifically assessed in the context of these environments. In colonies with differentiated hygienic behaviors, the metapodal shield showed a higher classification rate between groups (70%) than the genitoventral shield (64%), and it was the only structure that showed significant size differences between groups (p < 0.001). In mites from different geographic regions, the metapodal shield also exhibited a higher classification rate (78%) than the genitoventral shield (65%), with no significant difference in the size of the shields between the mite populations. Significant differences in fluctuating asymmetry were observed in the shape and size (p < 0.001) of the pair of metapodal shields and the shape of the genitoventral shield (p < 0.001). The results provide important methodological and ecological insights, highlighting the metapodal shield as a reliable structure for assessing shape, size, and fluctuating asymmetry.

In this study, we used an integrative approach combining morphological data, geometric morphometric analysis of wings, and ecological niche overlap analysis to elucidate the true identity of O. tataira. For the morphological study, 923 specimens and the lectotype of Trigona tataira (= O. tataira) were examined, 470 wings were used for geometric morphometry, and 106 unique occurrence records were used for niche overlap analysis. In the morphological study, three species/morphospecies were identified: morphospecies 1 (morphologically corresponding to O. tataira), morphospecies 2 (morphologically corresponding to O. cagafogo), and morphospecies 3 (a new species for the genus). The geometric morphometry of the wings corroborated the results of the morphological study. The ecological niche overlap analysis, despite indicating a small niche overlap between O. tataira and O. cagafogo, also corroborated the results of the morphological and morphometric studies.

Unlike A. mellifera, E. fervens reached flowers by contacting stigmas or the anthers with their abdomen, depositing more pollen grains (> 80) than A. mellifera. Artificial pollination treatments with the two pinned-bee types resulted in fruits of similar weights regardless of pollination intensity. Conversely, in natural pollination, weight differences were observed when the number of visits increased. E. fervens provided at least 132 pollen grains with > 3 visits: the threshold necessary for producing commercial fruits. The visitation frequency registered exceeded this minimum reaching one visit every 10 min. Other factors, such as pollination date and plant, influenced fruit production. Few visits are enough for obtaining commercial fruits: being an immature fruit, squash does not require seed development, besides species with separate flowers developed strategies to achieve rapid pollen saturation.
