populations of Glechoma longituba has shown that male carpenter bees (Xylocopa sinensis) are responsible for most of the nectar robbing from these flowers, while female bees account for little nectar robbing, demonstrating distinct behavioural differentiation between male and female bees in visiting ...
Similar case of female-specific regulation of germline and soma, by feminizer, has been reported in honey bees26. When parental RNAi was used by injecting Tctra dsRNA into adult females to silence the expression of the gene coding for Tctra during early embryogenesis, all the larvae hatched ...
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 ...
Organization and communication in social bees have interested researchers for a long time. The most studied among them is the domesticated Western honeybee,Apis mellifera. However, less is known about the primitive eusocial species (i.e. species having a solitary phase in their life cycle), such...
Queen Bees and Alpha Males: Are successful women more competitive than successful men? Two studies carried out in Switzerland examined different explanations forthe "Queen Bee (QB)-phenomenon." In Study 1 (N = 315), female managers(vs. subordinates) identied with successful women and supported ...
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 ...
In addition to the quantity of the marking secretion, its composition likely plays a decisive role for male attractiveness. InP. triangulum, the composition of the males’ marking secretion has presumably been influenced by a female sensory bias [53–55]. FemaleP. triangulumuse (Z)-11-eicosen...

for a heritable microbe, the advantage of killing males must only slightly increase the ®tness of infected female siblings; whereas for a male-killing nuclear gene to be selectively favoured, the ®tness of female siblings must increase at least two-fold (Werren, 1987). The biology of ...
Such high-quality nectar in large volumes should attract bees39. The bottom of the inflorescence has more female flowers and thus more nectar compared with the top of the inflorescence. This change in nectar availability may improve plant fitness20,39, as pollinatorys may avoid the female-phase...
