Sexual dimorphism and morphometric characterization of Centris tarsata Smith, 1874, Hymenoptera: Apidae in different environments

Sexual dimorphism and morphometric characterization of Centris tarsata Smith, 1874, Hymenoptera: Apidae in different environments

Solitary bees Apidae: Centridini are important pollinators of Malpighia emarginata DC. Malpighiales: Malpighiaceae. However, there are few studies on the characterization of populations of this species in areas with orchards and their surroundings. This study analyzed the morphometric variability and sexual dimorphism of Centris tarsata Smith, sampled in artificial nests installed at four different vegetation types. The right forewings of 168 individuals were dissected, photographed, and the images processed in TpsUtil and brought to the TpsDig2 version 2.12 for plotting 18 landmarks by geometric morphometrics. Data were analyzed through Principal Components Analysis PCA, Canonical Variables CV, and cross-validation in order to test the correct classification of each individual in the CV. In addition, the size analysis through the centroid size was used and subsequently the univariate analysis ANOVA and Tukey test were conducted. Different environmental conditions may influence the morphometric intrassexual pattern of C. tarsata and promote sexual selection. Sexual dimorphism of C. tarsata was observed, which can be a determining factor to favor distinct biological characteristics in an evolutionary process, supporting the understanding of ecological, biological, morphogenetic, and behavioral factors in the agro-ecosystem.

Las abejas solitarias Apidae: Centridini son importantes polinizadoras de Malpighia emarginata DC. Malpighiales: Malpighiaceae. No obstante, existen pocos estudios sobre la caracterización de las poblaciones de esta especie, en áreas de plantaciones y su entorno. En este estudio fueron analizadas la variabilidad morfométrica y dimorfismo sexual de Centris tarsata Smith, recolectada en nidos artificiales instalados en cuatro tipos de vegetación. Para el estudio, se disecó el ala anterior derecha de 168 individuos, fotografiadas, y las imágenes fueron transformadas en TpsUtil y llevadas al TpsDig2 versión 2.12 para marcar 18 puntos anatómicos, usando el método de morfometría geométrica. Los datos fueron analizados a través de Análisis de Componentes Principales ACP, Variables Canónicas VC y prueba de validación cruzada, dirigida a una correcta clasificación de cada individuo en VC. Además, el análisis del tamaño de ala fue utilizado mediante el tamaño del centroide y posteriormente se hizo un análisis de varianza, comparando los tratamientos con una prueba de Tukey. Se encontró que las diferentes condiciones ambientales pueden influenciar en el Patrón morfométrico intrassexual de las abejas C. tarsata y promover selección sexual. Fue posible observar el dimorfismo sexual de C. tarsata, lo que puede ser un factor determinante para favorecer características biológicas distintas en un proceso evolutivo, contribuyendo, así, en la comprensión de los factores ecológicos, biológicos, morfogenéticos y de comportamiento, relacionados con su función en un agroecosistema.
