Natural enemies are one of the main mortality factors in bees and wasps attacking either immature stages or adults of their hosts. Dipterans of the genus Physocephala (Diptera: Conopidae) are parasitoids that attack adult bees during their field activities, and the parasitoid larvae develop inside the host abdomen. However, little is known about the biology of these natural enemies and their interactions with their solitary bee hosts. This study is aimed at analyzing attacks by conopid flies in ...

Differences in the timing of exoskeleton melanization and sclerotization are evident when comparing eusocial and solitary bees. This cuticular maturation heterochrony may be associated with life style, considering that eusocial bees remain protected inside the nest for many days after emergence, while the solitary bees immediately start outside activities. To address this issue, we characterized gene expression using large-scale RNA sequencing (RNA-seq), and quantified cuticular hydrocarbon (CHC...

Bees are important components of mutualistic interactions with plants, playing a key role as pollinators of both wild and crop plants. In this context, studies on the plants visited by bees are important to determining conservation strategies. We investigated the use of floral resources by the trap-nesting bee species sampled in a semideciduous forest fragment. Trap nests were set in the forest fragment in three different zones: forest edge, 250 m away from the edge and 500 m away from the fores...

AbstractAlthough orchid bees (Apidae: Euglossini) are known as key pollinators in tropical ecosystems, knowledge of their floral sources is still scarce, especially for those species commonly found in urban environments. We aimed to identify the pollen, nectar and resin sources used by the widespread species Euglossa cordata in an urban area in south-eastern Brazil. The residual pollen from 81 brood cells of nine nests reactivated between October 2013 and December 2014 was acetolysed and analyse...

Natural enemies are important components of solitary bee communities that nest in preexisting cavities because they act as a relevant mortality factor and can regulate population growth. Despite this, the natural enemy-host interaction remains poorly investigated. This research aimed to determine the composition of the community, the structure of the interaction network, and niche overlap and breadth of natural enemy species in areas of Cerrado (Brazilian savanna) and Semideciduous seasonal fore...

Euglossini bees are able to fly long distances, which could help to maintain gene flow among widely separated populations. In order to investigate if different environmental conditions affect morphological variation in Euglossa annectans and Euglossa truncata, we analyzed the patterns of venation of the forewings of 310 individuals, sampled in the same six locations for the two species. Populations from the two species clustered in a similar way, following the phytophysiognomy of the sampling si...

Although bees have been demonstrated to be abundant and species-rich in cities, several studies pointed out that oligolectic species are scarce in those urban landscapes. Oligolectic species are those whose females collect pollen from a few closely related plant species or from some species belonging to the same or related plant families. We studied three nest aggregations of the oligolectic bee Centris collaris (Apidae) in an urban area. Nest aggregations were found underneath building ramps at...

A new species of Coelioxoides Cresson (Apidae), Coelioxoides piscicauda sp. nov. Rocha-Filho from Sao Paulo State, Brazil, is described. A key to the four recognized species of the genus, C . exulans (Holmberg), C . piscicauda sp. nov., C . punctipennis Cresson, and C . waltheriae Ducke, is provided. In addition, new host records of Coelioxoides are presented as well as a compilation of published data on species of Tetrapedia Klug associated with this cleptoparasitic genus.

The genus Centris is by far the most diverse group of oil-collecting bees worldwide. In spite of its broad distributional range through Americas, data on the biology of several species remain unknown. We aimed to study the nesting ecology of Centris (Melacentris) conspersa in two islands in the Atlantic Forest domain, Southeastern Brazil. In both areas, nests were constructed in sloping, shaded areas of clayey soil. Two specimens emerged around one year after the brood cells were collected at th...
