Las abejas melíferas son el principal insecto polinizador de los manzanos. Sin embargo, durante las visitas a las flores las abejas pueden abordarlas desde arriba entrando en contacto con las anteras o por el costado posándose sobre los pétalos, siendo la primera forma la que logra una mejor polinización. El objetivo de este estudio fue analizar el comportamiento de las abejas melíferas mientras visitan las flores de los manzanos de las variedades Cripps Pink y Red Chief. En ambos cultivos se observó que las abejas prefieren colectar polen en la mañana y néctar en la tarde. Mientras las abejas que colectaban solo néctar o que colectaban polen y néctar abordaban las flores por arriba o por el costado, las abejas que colectaban sólo polen accedían a la flor principalmente desde arriba. Algunas abejas durante el vuelo de pecoreo abordaban las flores únicamente por arriba o por el costado (abordajes constantes), mientras que otras podían cambiar entre ambas formas (abordajes no constantes), siendo las que colectaban sólo polen las que presentaron más vuelos constantes. El 37 % del total de abejas observadas abordó las flores por el costado aportando probablemente muy poco a la polinización. Un manejo de las colmenas que incrementara elnúmero de abejas que colecta polen (por ejemplo agregando panales con huevos y larvas o retirando reservas de polen) mejoraría la polinización de los manzanos.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Summary: The production of quality apples heavily depends on effective pollination. Honey bees are the main pollinator insect of apple trees. However, during the visits to the flowers, the bees can approach them from above by coming in contact with the anthers, or by the side posing themselves on the petals, being the first form the one that achieves a better pollination. The aim of this study was to analyze the behavior of the honey bees visiting the flowers of apple trees of the Cripps Pink and Red Chief varieties. In both plantations, it was observed that bees prefer to collect pollen in the morning and nectar in the afternoon. Bees collecting only nectar or collecting pollen and nectar approached flowers from above or from the side, and bees collecting only pollen accessed the flower mainly from above. Some bees during the foraging flight approached the flowers only from above or from the side (constant boardings), while others could change between both forms (not-constant boardings), and the bees that collected only pollen presented more constant flights. Thirty-seven percent of the total number of bees observed approached to the flowers from the side, contributing probably very little to pollination. Management of colonies that increase the number of bees collecting pollen (for example by adding combs with eggs and larvae or removing pollen reserves) would improve the pollination of apple trees.]]></p></abstract>
