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 ... -
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 ... -
Stingless Bees in applied pollination: practice and perspectives
(Apidologie, 2006-06-22)At present, numbers of both wild and managed bee colonies are declining rapidly, causing global concern for pollination services. Stingless bees play an important ecological role as pollinators of many wild plant species ... -
Reproductive biology of Varroa destructor in Africanized honey bees (Apis mellifera)
(Experimental and applied Acaralogy Springer, 2009-10-23)Since its first contact with Apis mellifera, the population dynamics of the parasitic mite Varroa destructor varies from one region to another. In many regions of the world, apiculture has come to depend on the use of ... -
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 ... -
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 ... -
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 ... -
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 ... -
Comparación de la habilidad reproductiva y mortalidad del ácaro Varroa destructor en celdas con cría de obrera y zángano en abejas africanizadas de Costa Rica
(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 ... -
Presence of Nosema ceranae in Africanized honey bee colonies in Costa Rica
(Journal of Apicultural Research, 2015-03-25)Nosemosis is a severe disease caused by the microsporidian Nosema sp. affecting adult honey bees (Apis mellifera) (Bailey and Ball, 1991). Nosema spores infect the epithelial layer of the ventriculus and midgut of adult ... -
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, ... -
An insight into the antibiofilm properties of Costa Rican stingless bee honeys
(Journal of Wound Care, 2017-04-05)Our objective is to examine the the antibiofilm properties of stingless bee honeys. Meliponini honeys from Costa Rica were examined along with Medihoney as a reference. All honeys were submitted to a screening composed of ... -
