dct:abstract

Although the tribe Euglossini includes more than 200 described species belonging to five genera, information on natural enemies of those bees is scarce. This paper reports attacks on nests by natural enemies and the parasitism of adult females of species of the genus Euglossa. Euglossa nests were obtained using trap-nests, distributed in different sites among three cities in the state of Sao Paulo, Brazil: Sao Carlos, Ribeirao Preto, and Indaiatuba. During the period of study 46 nests of Euglossa were obtained. Euglossa cordata occupied 22 traps, E. townsendi occupied seven traps, and E. truncata Rebelo & Moure occupied one trap. It was not possible to identify the species of Euglossa from other 16 traps. Three parasitoids and two cleptoparasites were associated with the nests. Cells were attacked by the parasitoid wasp Polistomorpha fasciata (Westwood) (Leucospidae) (3 nests), by the gregarious parasitoid wasp Aximopsis masneri Gates (Eurytomidae) (2 nests) and by the beefly Anthrax oedipus Fabricius (Bombyliidae) (2 nests). Nests were also attacked by two cleptoparasitic bees of the family Megachilidae: Coelioxys costaricensis Cockerell (1 nest) and Hoplostelis nigritula (Friese) (2 nests). Moreover, seven E. cordata females and one E. townsendi female were parasitized by the endoparasitoid fly Melaloncha ronnai Borgmeier (Phoridae).
