Learnt information in species-specific ‘trail pheromone’ communication in stingless bees
(Elsevier, 2013)Specificity in biological signalling systems is often important to keep information private. Foragers of several species of stingless bees deposit chemical marking signals to guide nestmates to food sources. The markings ... -
Nest-specific composition of the trail pheromone of the stingless bee Trigona corvina within populations
(Springer, 2012)Social insects have evolved highly developed communication systems, enabling them to coordinate complex interactions in their colonies. Pheromones play a major role in the coordination of many tasks. In Trigona corvina, a ... -
Physicochemical differentiation of stingless bee honeys from Costa Rica
(Taylor and Francis Group, 2021-04-06)We characterized Tetragonisca angustula and Melipona beecheii honeys produced in Costa Rica according to their physical and chemical properties. Moreover, we found critical parameters that distinguish the honeys from each ... -

(Universidad Nacional, Costa Rica, 2021-04-12)Se estudió la prevalencia del microsporidio Nosema spp. en un apiario de 10 colmenas de abejas africanizadas en Atenas-Alajuela, Costa Rica, durante julio a noviembre 2017. Además, se comparó el número de esporas y el nivel ... -
Reproduction of Varroa destructor and offspring mortality in worker and drone brood cells of Africanized honey bees
(Springer, 2012-01-24)Varroa destructor is known to be the most serious parasite of Apis mellifera worldwide. In order to reproduce varroa females enter worker or drone brood shortly before the cell is sealed. From March to December 2008, the ... -
Situación del pequeño escarabajo, Aethina tumida, en colmenas de abejas africanizadas (Apis mellifera) en Costa Rica: Muestreo de apiarios 2014-2017
(2018-05-18)El primer reporte sobre la presencia del pequeño escarabajo de la colmena, Aethina tumida en Centroamérica se dio en El Salvador en el 2013, luego se confirmó en Nicaragua en el 2014, lo cual aumenta el riesgo de su ... -
The antimicrobial activity and microbiological safety of stingless bee honeys from Costa Rica
(International Bee Research AssociationTaylor and Francis, 2014)Stingless bee honeys from Costa Rica possess etnopharmacological value mainly as a wound dressing. The microbiological study by APHA methods reported that 83 % of the honeys analysed had microbial counts that comply with ...
