Resumen:

The Feijoa “Guayabo del país” (Acca sellowiana) is a native Myrtaceae whose fruits have a great commercial potential for their nutritive properties. The objectives of this study were to determine the extent to which fruit production depends on biotic pollination and to identify potential pollinators in Uruguay. Two farms and three park, located in Salto and Canelones were used for the study. The percentage of fruit set in the branches excluding pollinators did not exceed 5.1%, whereas in the branches with free access of pollinators it varied between 10.4% (Salto) and 90.9% (park trees, Canelones). A total of 28 insect species and 3 Passeriforme species were identified on the flower varying with the region. Apis mellifera were present on all plantations with high frequency. Remarkably, 7 species of native bees and 3 species of native passerines were found only in the southern trees of the country. Some pollinators can be managed to improve production, of commercial quality, like honeybees or bumblebees.


A goiaba “Guayabo del país” (Acca sellowiana) é uma Myrtaceae nativa cujos frutos apresentam grande potencial comercial por suas propriedades nutritivas. Os objetivos deste estudo foram determinar em que medida a produção de frutos depende da polinização biótica e identificar potenciais polinizadores no Uruguai. Duas fazendas e três parques, localizados em Salto e Canelones, foram utilizados para o estudo. A porcentagem de frutificação nos ramos excluindo polinizadores não ultrapassou 5,1%, enquanto nos ramos com livre acesso de polinizadores variou entre 10,4% (Salto) e 90,9% (árvores do parque, Canelones). Um total de 28 espécies de insetos e 3 espécies de Passeriformes foram identificados na flor variando com a região. Apis mellifera esteve presente em todos os plantios com alta frequência. Notavelmente, 7 espécies de abelhas nativas e 3 espécies de passeriformes nativos foram encontrados apenas nas árvores do sul do país. Alguns polinizadores podem ser manejados para melhorar a produção, de qualidade comercial, como abelhas ou zangões.
