Rapid evolution of chemosensory receptor genes in a pair of sibling species of orchid bees (Apidae: Euglossini). [PDF]

open access: yes, 2015
BackgroundInsects rely more on chemical signals (semiochemicals) than on any other sensory modality to find, identify, and choose mates. In most insects, pheromone production is typically regulated through biosynthetic pathways, whereas pheromone sensory

Molecular identification of species of the Genus Euglossa Latreille (Hymenoptera: Apidae, Euglossini) [PDF]

open access: yesNeotropical Entomology, 2007
Euglossine bees interact with more than 60 plant families of the Neotropical region. The richness and abundance of these bees have been intensively studied in different ecosystems using the methodology of capturing males with chemical baits. Females are poorly known for most of the species and morphological characters for their taxonomic classification

Bionomics and sociological aspects of Euglossa fimbriata (Apidae, Euglossini)

open access: yesGenetics and Molecular Research, 2009
The nesting biology and the social structure of Euglossa fimbriata were studied based on two original nests found on the campus of the University of São Paulo, Ribeirão Preto, Brazil. Nest 1 contained two inseminated females, 39 sealed cells, one cell being provisioned, and six old and empty cells.
