Queens play an essential role in the colonies of stingless bees. Typically, only one queen
occurs in a colony at any time, and she dominates the egg laying. Their presence maintains …

The reproductive biology of stingless bees is poorly understood, especially when compared
to other groups of social bees with great ecological and economic importance. However …

All hymenopterans (bees, ants, wasps, and sawflies) have haplodiploid sex determination.
Generally, this involves haploid males developing from unfertilized eggs and diploid females …

Human-induced shifts in species' ranges can increase contact between closely related
species and lead to reproductive interference. In Australia, climate change and trade in …

In temperate regions of the world dominated by intensive agriculture, cities harbor a rich
diversity and abundance of bee species, often exceeding those of the rural environment. In …

Discrepancies in mitochondrial and nuclear genetic data are often interpreted as evidence
of hybridisation. We re-examined reports of hybridisation in three cryptic stingless bee …

Female mating frequency varies. Determining the causes of this variation is an active
research area. We tested the hypothesis that in stingless bees, Meliponini, single mating is …

The buff-tailed bumblebee Bombus terrestris presents two distinct colony phenotypes in
which some colonies already start producing males very early in the season, while others …

To start a new colony, stingless bee queens need the help of workers. The first tasks of these
workers are finding and inspecting potential nest sites, building nest-structures at the …

Stingless bee brood rearing is a complex process that involves workers performing a
number of different jobs and requires coordination with the queen. After a new brood cell is …
