Las abejas con hábitos crepusculares y nocturnos han sido pobremente estudiadas en Bolivia, donde la mayoría de los estudios han estado centrados en Apis mellifera. Las redes de interacción permiten cuantificar la biodiversidad y comprender fenómenos tanto naturales como de origen antrópicos y son de gran utilidad para el estudio de las interacciones planta-polinizador. Este trabajo se realizó en un bosque de transición de Amazonia y Bosque Seco Chiquitano, para conocer la intensidad y características de las interacciones entre abejas nocturnas y plantas locales, utilizando trampas de luz para capturar a las abejas nocturnas. Se colectaron 19 individuos durante tres noches. Identificamos cuatro especies de la familia Halictidae, tribu Augochlorini, de las cuales dos pertenecen al género Megalopta y dos son especies no identificadas de la misma tribu. Realizamos también una palinoteca del lugar y sus alrededores. Utilizando comparación morfológica entre los preparados de la palinoteca, los obtenidos de los cuerpos de las abejas y bibliografía especializada, encontramos doce morfoespecies de polen presentes en los cuerpos de las abejas, de las cuales tenía mayor frecuencia relativa los pertenecientes a las familias Lythraceae y Asteraceae. Como resultado tenemos una aproximación a la red de interacción, que nos permite indagar de manera mas profunda la interacción de este tipo de abejas y las plantas que visitan.

Stingless bees (Apidae: Meliponini) primarily feed on nectar and pollen from a wide diversity of flowering plants. By doing so they pollinate these flowers thus contributing to biodiversity and ecosystem stability. The pollen they collect provides essential nutrients for brood rearing and colony growth. This study aimed to characterize the floral resources available to stingless bees in a Tucumano-Boliviano Forest, including their pollen protein content and, through construction of an interaction network and preference analysis, understand their foraging behavior. Only 8 out of 25 pollen types sampled within the study site around the meliponaries were collected by the bees. Pollen pots also contained many types of pollen not from to plant species in the study area. Pollen from Capsicum minutiflorum (Solanaceae) was dominant in almost every hive (up to 98.7% of pollen composition). Additionally, protein content of Capsicum minutiflorum pollen (67% w/w) was the highest of all species present at the study site and explained almost 100% of the protein content in the hives of Tetragonisca angustula , and Scaptotrigona depilis , and almost 80% and 75% of the protein content in those of Scaptotrigona polysticta and Melipona rufiventris , respectively. These results suggest that stingless bees preferentially collect pollen with higher protein content.

Reconocimiento de parentesco intraespecífico e interespecífico de Scaptotrigona aff. postica (APIDAE: MELIPONINI)
(2024) Sara Morales-Acosta; Raquel Mondino; J. Aylin Torres-Mostacedo; M. Adler
Las abejas sin aguijón tienen una gran importancia en la región de América Central y Sud América por su diversidad, potencial polinizador y producción de miel. Son abejas eusociales organizadas en castas donde cada colonia tiene una sola reina. Surge la pregunta si es que estas pueden reconocer y discriminar entre miembros de la misma colmena, de colmenas emparentadas de la misma especie, como también individuos de otra especie. En este trabajo se midió el reconocimiento de parentesco entre abejas sin aguijón basados en el número de interacciones negativas que tenían entre sí en un tiempo definido y utilizando un Índice de Agresividad. Para esto se hizo interactuar a dos individuos guardianes de Scaptotrigona aff. postica de la misma colmena, de una colmena emparentada, de una colmena no emparentada y con un individuo de otra especie (Tetragonisca fiebrigi) para registrar sus comportamientos en el tiempo y definir si sus interacciones son amigables o agresivas. Se encontró que, con miembros de colmenas no emparentadas y de diferente especie, S. aff. postica tienen muchas más interacciones agresivas que con miembros de la misma colmena o de colmenas emparentadas. Esto nos indica que S. aff. postica presenta reconocimiento de parentesco y puede discriminar individuos intraespecíficamente en relación a este factor, como también reconocer y discriminar individuos de otra especie del mismo grupo.

Introduction. About 60% of emerging infectious diseases are zoonotic, originating mainly from wildlife. Objective. To identify knowledge, attitudes, and practices associated with zoonotic transmission risks in communities in urban, rural, and protected areas to prevent potential zoonotic outbreaks. Methods. Cross-sectional study in a representative sample stratified by zones (urban, rural and protected areas) and age groups. A standardized questionnaire in Spanish and Quechua, adapted to the local context, was applied to explore sociodemographic data, contact with animals, attitudes towards wildlife, their trade and consumption, and knowledge about zoonotic diseases and sources of information. Trained local interviewers visited households and recorded information using the ODK application on electronic tablets. Frequencies were described and the chi-square test was used to compare the distribution by area. Results. A total of 922 people participated. Rabies was recognized in the highest percentage (57.3%), Chagas disease (36.1%) and yellow fever (11.5%). Few participants had previous training on zoonosis (8.9%), the majority in the protected area (13.5%). There was concern about zoonosis outbreaks (70.7%), and (70.7%) indicated that wild animals should be protected, significantly different between study areas. (76.4%) have close contact with animals; (62.5%) handle some of them freshly slaughtered; (35.2%) noted the presence of animal feces in or near food; (13.3%) indicated selling, ingesting or sharing dead animals collected from animals. Conclusions. Low knowledge, perceptions, and practices of high zoonotic risk in human-animal interactions were identified, significantly different between areas of residence.

Approximately 60% of all emerging infectious diseases (EIDs) events in humans are attributed to zoonotic origins, with most originating in wildlife, where wildlife trade and consumption represent significant risk factors. Latin America is one of the most biodiverse regions in the world and faces considerable challenges in terms of wildlife preservation. Previous efforts to control wildlife trade and consumption practices worldwide have primarily focused on conservation, overlooking the health component when developing behavioral change programs. Similarly, some initiatives overlooked the needs and characteristics of local communities, making it necessary to consider a unifying and integrative approach such as the One Health approach. This study employed multicenter and mixed-methods approaches, including a Knowledge, Attitudes, and Practices (KAP) survey, interviews with key actors, focus group discussions, and participatory community-based action. By identifying the main drivers in urban and rural communities across Latin America, we co-construct strategies tailored to the local context with the communities to educate, raise awareness of zoonotic risk and wildlife conservation practices, and ultimately change behavior within the population. The project involved interdisciplinary and participatory work between the project team, local authorities, and community representatives, with One Health approach. This collaboration enabled us to identify local issues that impact human, animal, and environmental health and implement actions aimed at reducing the risk of zoonotic diseases and promoting biodiversity conservation.
