“…We note that for the above studies, bees were exposed to toxic treatments with extracts in laboratory experiments, whilehere we report that T. recursa spontaneously consumed C. micans. However, in more similar circumstances, Del Lama and Peruquetti (2006) observed that the consumption of the toxic plant Caesalpinia peltophoroides in a natural setting caused a large number of mortalities in bees, with 273 indi- viduals of 20 different species dying after visiting the plant. Toxicity seemed to vary by time and individual tree.…”

In this paper we present observations of individuals of the bee species Trigona recursa feeding on the fruits of Crotalaria micans. This plant, which contains pyrrolizidine alkaloids, is known to be toxic to humans, mammals and poultry. Over the course of three days, we observed a large number of bees feeding on many individual Crotalaria micans plants in an urban fragment of Brazilian Savanna. The bees preferred greener fruits, which are the softest and most toxic. Consumption of the plant had no immediately apparent fatal effect on the bees, since we did not find any dead individuals near the observation site. Some insect species are known to use pyrrolizidine and alkaloids for defense by incorporating them into their body or using them as precursors to pheromones. Trigona recursa and other bee species have not been previously recorded consuming Crotalaria micans and it is unclear what their motivation may be. We present these observations as a novel finding of the feeding behavior of Trigona recursa.

“…The analysis was performed in R, using the Vegan package. The anther type and the flower's resources of each plant were determined according to literature (see Anderson 1979;Buchmann 1983;Oliveira et al 1987;Oliveira and Gibbs 1994;Kill et al 2000;Carvalho and Oliveira 2003;Fracasso and Sazima 2004;Pereira and Barbosa 2004;Andena et al 2005;Ragusa-Netto 2005;Souza and Lorenzi 2005;Del Lama and Peruquetti 2006;Filho et al 2007;Pool 2009). …”

Oil-collecting bee–flower interaction network: do bee size and anther type influence the use of pollen sources?

International audienceAbstractPollination is an ecosystem service sustained by a differentiated use of resources among sympatric species. The bee size can influence the similarity in the use of resources, and poricidal anthers limit the access to pollen. Therefore, we evaluated the influence of body size and the anther type of pollen sources in Centridini–flower interaction network. We expected that the low niche overlap, promoted by these morphological parameters, would result in the formation of subgroups and lead to greater network resilience. We studied 15 bee species (n = 73 females) and identified their pollen sources. The bee size and anther type influenced the formation of subgroups in the community, and the larger bees used a higher proportion of flowers with poricidal anthers. Only the anther type influenced the robustness of the network. We conclude that the parameters analyzed influence both the use of resources by oil-collecting bees and their food niche breadth
