An insight into the antibiofilm properties of Costa Rican stingless bee honeys
(Journal of Wound Care, 2017-04-05)Objective: There is an increasing search for antibiofilm agents that either have specific activity against biofilms or may act in synergy with antimicrobials. Our objective is to examine the the antibiofilm properties of ... -
An unusual recruitment strategy in a mass-recruiting stingless bee, Partamona orizabaensis
(Springer-Verlag Berlin Heidelberg, 2016-07-13)Foragers of several stingless bee species deposit attractive scent marks on solid substrates to precisely recruit nestmates to food. Interestingly, Partamona workers quickly recruit large numbers of nest mates to resources, ... -
Asociación entre abejas sin aguijón (Apidae, Meliponini) y la flora del bosque seco en la región norte de Guanacaste, Costa Rica
(Universidad Nacional, Costa Rica, 2019-01-01)Las abejas sin aguijón son importantes polinizadores en regiones tropicales y subtropicales; están asociadas a la flora que les proporciona alimento, sitios para anidamiento, resinas, savia y exudados. Se buscó determinar ... -
Comparison of the reproductive ability of Varroa destructor (Mesostigmata:Varroidae) in worker and drone brood of Africanized honey bees (Apis mellifera)
(Universidad Nacional, Costa Rica, 2014-10-31)Se estudió la reproducción del ácaro Varroa destructor en celdas con cría de obrera y zángano. Además se evaluó la mortalidad de la progenie de V. destructor, especialmente la muerte o ausencia del macho. El estudio se ... -
Distribución del Pequeño Escarabajo de la Colmena, Aethina tumida, en abejas africanizadas (Apis mellifera) en diferentes zonas apícolas de Costa Rica
(Universidad Nacional, Costa Rica, 2020-07-01)El primer reporte sobre la presencia del Pequeño Escarabajo de la Colmena (PEC), Aethina tumida, en Costa Rica, se realizó el 25 de agosto 2015, en La Cruz, Guanacaste; lo cual aumenta el riesgo de dispersión a otras zonas ... -
Efficacy of Piper (Piperaceae) extracts for control of common home and garden insect pests
(Entomological Society of America, 2004)Extracts from three species of the plant family Piperaceae, Piper nigrum [L.], Piper guineense [Schum & Thonn], and Piper tuberculatum [Jacq.], were tested for efficacy against insects from five orders. All three species ... -
Floral biology, pollination ecology and seed production of the ornamental plant Salvia splendens Sello
(Universidad Nacional, Costa Rica., 2002)In this paper, the floral biology and pollination ecology of Salvia splendens are described. All flower characteristics (red corolla, large tubular flowers with abundant but dilute nectar) indicate that S. splendens is ... -
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 ... -
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 ... -
Prevalencia de Nosema spp. (Microsporidia: Nosematidae) en abejas africanizadas en Atenas, Costa Rica: número de esporas y nivel de infección durante la época lluviosa
(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 ... -
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 ...
