Tetragonisca Angustula

Individual heterogeneity within societies provides opportunities to test hypotheses about adaptive neural investment in the context of group cooperation. Here we explore neural investment in defense specialist soldiers of the eusocial stingless bee (Tetragonisca angustula) which are age sub-specialized on distinct defense tasks, and have an overall higher lifetime task repertoire than other sterile workers within the colony. Consistent with predicted behavioral demands, soldiers had higher relative visual (optic lobe) investment than non-soldiers but only during the period when they were performing the most visually demanding defense task (hovering guarding). As soldiers aged into the less visually demanding task of standing guarding this difference disappeared. Neural investment was otherwise similar across all colony members. Despite having larger task repertoires, soldiers had similar absolute brain size and smaller relative brain size compared to other workers, meaning that lifetime task repertoire size was a poor predictor of brain size. Together, our results are consistent with the specialized but flexible defense strategies of this species, broadening our understanding of how neurobiology mediates age and morphological task specialization in highly cooperative societies.

<p>La interacción planta-abeja puede generar productos de la colmena con diferentes características fisicoquímicas, bioactivos y actividad antimicrobiana. Por lo cual, en este trabajo se determinó la composición química de conglomerados o agregados de polen colectados de 12 colmenas establecidas en Chiapas, México, en los municipios Tapachula, Mazatán y Cacahoatán, dentro de tres meliponarios comerciales asociados a las especies: <em>Melipona beecheii</em>, <em>Scaptotrigona mexicana</em> y <em>Tetragonisca angustula</em>. Asimismo, se evaluó el efecto de los agregados de polen en <em>Colletotrichum gloeosporioides</em>. Se encontró una composición química muy diversa independientemente de la especie de abeja. El polen obtenido de colmenas con <em>M. beecheii</em> tuvieron la mayor cantidad de fenoles, flavonoides y acidez libre. Estas propiedades, en adición de la capacidad antioxidante (trolox), glucosa y pH, estuvieron asociados a la inhibición del crecimiento <em>in vitro</em> de<em> C. gloeosporioides</em>. La velocidad de crecimiento radial del hongo durante nueve días fue de 0.013 a 0.009 mm h-1 con extractos de polen, 44 % menor que el efecto del clorotalonil. La actividad antifúngica de los extractos de polen fue de 65 y 37 % para <em>M. beecheii</em>, 57 y 16 % para <em>T. angustula</em> y 60 y 30 % para S. mexicana, respecto al tratamiento testigo y a la dosis más alta de clorotalonil, respectivamente.</p>
