The selection and breeding of Apis mellifera colonies with a natural ability to survive Varroa destructor provide long-term solution for sustainable apiculture. In Argentina, selected honey bee stock showing resistance the mite (named R stock) has been identified characterized under laboratory field conditions. Currently, this material is being preserved further evaluations in commercial beekeeping system. study, we analyzed population strength, levels production during two consecutive seasons (a total 16 surveyed apiaries). Results indicated low adult infestation from all apiaries (mean both seasons: 0.3 ± 0.5% spring; 1.5 2.0% summer). colony strength food stores were similar between seasons, yield per apiary ranged within average registered region. During each following autumn, subgroup was used compare level non-selected mite-susceptible S stock). Overall, exhibited lower worker brood population, higher autumn compared colonies. Our results indicate that displayed significant potential maintain phenotype system, better regulates its overwintering conditions, exhibits commercially adequate production. Present tools improving environment-friendly strategies control varroosis productive

Abstract Honey production in Mexico is an ancient economic, social, and biocultural activity for indigenous communities, Mayas, Totonacs, among others. Stingless bee honeys are used traditional medicine to treat gastrointestinal, respiratory, dermatological, ophthalmic ailments as they contain compounds with antioxidant, antibacterial, anti-inflammatory, antifungal activities. Here, a comprehensive physicochemical characterization of Mexican stingless presented contribution strengthening the practice meliponiculture by native Mayan Totonac communities. By delivering information on main parameters Melipona beecheii Scaptotrigona mexicana , it intended increase their commercial value different regions Mexico, taking into consideration zootechnical management techniques these A statistical analysis was performed identify if there were significant differences evaluated. Significant observed moisture level, pH, sugar composition, HMF content between at least two analyzed.

This paper presents the concept of a Beekeeping Knowledge and Innovation System (B-KIS). is closely related to Agricultural (AKIS) – both theoretically methodologically. By adopting B-KIS approach we can: a) depict general structure functioning activities aiming for knowledge development, innovation learning within apicultural sector; b) improve understanding how services beekeepers are embedded into national B-KIS; c) provide some conceptual elements support development or regionally adapted communication strategy improved sustainability beekeeping. From policy perspective, it important that becomes integrated strategic AKIS plans.
