We collected bees on 24 1-ha plots centered on particular plant species. We compared number of floral species and families (1) associated with individual female and male bees (via generalized linear mixed models) and (2) accumulated by each sex (using rarefaction); and (3) effect of ...
Generation of two sexes (male and female) is an essential and universal phenomenon among animals to reproduce and maintain their existence1. In spite of being such a widespread developmental process, different strategies have been adopted by different organisms to accomplish the same goal2. Insects ...
In honeybees, it boils down to whether a particular chromosomal location has the same version of a gene (called homozy- gous) or two different versions (heterozy- gous). Honeybees that have two different versions of the sex determination locus (SDL) develop female traits. Those that have...

The objective of the present study was to evaluate seed-set on four male-sterile, female-fertile soybean lines by using alfalfa leafcutting bees (Megachile rotundata(F.)) and honey bees (Apis mellifera(L.)) as pollinators. Seed-set was evaluated in summers 2003 and 2005 near Ames, Iowa,...
secretion changes substantially with the age of queens (as opposed to octadec-9-enoic acid, the main component of the mandibular gland secretion), reaching a maximum between 5- and 8-day-old queens [69]. Hydroxy- and oxo-acids may, thus, be candidates for further studies on female sex ...
some reptiles and in the silkworm Bombyx mori; in Drosophila 4A/XX and XO prevails; the signaling sex lethal–transformer–doublesex cascade in (some) insects; the diploid–haploid female–male determining system of honey bees; temperature-dependent sex determination in some insect and other species...
Female Philanthinae also possess an MG and a PPG [56–59]. Females of this subfamily mass-provision subterranean brood cells with paralyzed insects as food for their progeny (e.g. [34,35,37,60]). Since the larval provisions are prone to fungal infestation (e.g. [61]), at least som...
Female bees visit flowers both to gather nectar for their own energetic needs and to gather the pollen on which their offspring will feed. Some bees are oligolectic, i.e., they are fairly restricted in the range of plant species from which they gather pollen. Others, such as the ...
Female social insects represent a dramatic exception of the evolutionarily conserved physiological trade-off between reproduction and life span, where aging is positively correlated with reproduction. However, whether this facet of life history also pertains to male social insects, remains largely unknown....
