Resumo

Este experimento foi conduzido em Ribeirão Preto, SP, Brasil, de novembro de 2009 a abril de 2010, para identificar os visitantes florais e dentro deles quais são os polinizadores potenciais, em Passiflora cincinnata check for this species in other resources , o tipo de coleta efetuado por esses visitantes (néctar e ou pólen) e o comportamento de forrageamento dessas espécies. A freqüência dos insetos e o tipo de coleta, no decorrer do dia, foram obtidos por contagem nos dez primeiros minutos de cada horário, do amanhecer ao entardecer, com cinco repetições. Os insetos observados nas flores de P. cincinnata foram Oxaea flavescens check for this species in other resources (62,7%; Hymenoptera: Andrenidae), Euglossa check for this species in other resources sp. (10,1%; Hymenoptera: Apidae), Augochlora check for this species in other resources sp. (9,8%; Hymenoptera: Halictidae), Epicharis check for this species in other resources sp. (9,0%; Hymenoptera: Apidae) e Apis mellifera check for this species in other resources (8,4%; Hymenoptera: Apidae). As espécies O. flavescens, Euglossa sp., Augochlora sp. e Epicharis sp. coletaram néctar nas flores. Apenas a espécie A. mellifera coletou pólen. Todas as abelhas que visitaram as flores de P. cincinnata foram constantes: O. flavescens (100%), Euglossa sp. (66,7%), Augochlora sp. (61,1%), Epicharis sp. (58,33%) e A. mellifera (58,33%). Conclui-se que os polinizadores das flores de P. cincinnata foram abelhas de grande porte, sendo que as espécies de menor porte visitaram a flor sem efetuar a polinização.

Abstract

This experiment was conducted in Ribeirão Preto, SP, Brazil, from November 2009 until April 2010, to identify the floral visitors and within them what are the potential pollinators in Passiflora cincinnata check for this species in other resources , the type collection made by these visitors (nectar and/or pollen) and foraging behavior of these species. The frequency and type of insect collection, during the day, were obtained by counting the first ten minutes of each hour, from dawn to dusk, with five replicates. The insects found in flowers of P. cincinnata were Oxaea flavescens check for this species in other resources (62,7%; Hymenoptera: Andrenidae), Euglossa check for this species in other resources sp. (10,1%; Hymenoptera: Apidae), Augochlora check for this species in other resources sp. (9,8%; Hymenoptera: Halictidae), Epicharis check for this species in other resources sp. (9,0%; Hymenoptera: Apidae) and Apis mellifera check for this species in other resources (8,4%; Hymenoptera: Apidae). O. flavescens, Euglossa sp., Augochlora sp. and Epicharis sp. collected nectar in the flowers. Only A. mellifera collected pollen. All the bees that visited flowers of P. cincinnata were constant: O. flavescens (100%), Euglossa sp. (66,7%), Augochlora sp. (61,1%), Epicharis sp. (58,33%) and A. mellifera (58,33%). It can be concluded that the pollinators of flowers of P. cincinnata were large bees, while the smaller species visited the flowers without effecting pollination.
