Co-occurrence of three types of egg policing in the Norwegian wasp Dolichovespula norwegica
(SPRINGER, 2011)
In insect societies, workers often try to challenge the reproductive monopoly of the queen by laying their own eggs. Successful worker reproduction, however, is frequently prevented by queen policing or worker policing, ...
The queen is dead-long live the workers: intraspecific parasitism by workers in the stingless bee Melipona scutellaris
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Insect societies are well known for their high degree of cooperation, but their colonies can potentially be exploited by reproductive workers who lay unfertilized, male eggs, rather than work for the good of the colony. ...
Sex allocation in the polydomous leaf-cutting ant Acromyrmex balzani
(Springer, 2007-03-01)
Logistic regression analysis was used to analyse sex allocation in a population of the leaf-cutting ant Acromyrmex balzani occurring in a pasture in southern Brazil. The field sample consisted of 151 fungus-garden chambers ...

Worker laying in leafcutter ant Acromyrmex subterraneus brunneus (Formicidae, Attini)
(Wiley-Blackwell, 2007-04-01)
We studied the process of offspring production in queenless colonies of Acromyrmex subterraneus brunneus, and particularly evaluated the ovary development of workers as a function of their age. For this, subcolonies were ...

The number of reproductive workers in highly eusocial Hymenoptera: monogyny and monandry
(FUNPEC-EDITORA, 2009)
Haplodiploidy results in relatedness asymmetries between colony members of highly eusocial Hymenoptera. As a consequence, queen and reproductive workers are more related to their own sons than to each other's male offspring. ...
Trophallaxis and reproductive conflicts in social bees
(Birkhauser Verlag Ag, 2010-05-01)
In the eusocial Hymenoptera, reproductive division of labour is a key aspect of colony organisation. In most of its species, workers are sterile and are unable to reproduce, while the queen monopolises reproduction. When ...
