Abstract.  Bumble bee workers (Bombus bifarius, Hymenoptera: Apidae) exhibit aggression toward one another after the colony begins producing female reproductive offspring (the competition phase). Workers in competition phase colonies must continue to perform in‐nest tasks, such as nest thermoregulation, and to forage for food, to rear the reproductives to maturity. Therefore, competition phase workers are faced with potentially conflicting pressures to work for their colonies, or to compete for… 
Aggression, Social Interactions, and Reproduction in Orphaned (Bombus impatiens) Workers: Defining Dominance
TLDR
The results confirm aggression has a role in worker reproduction, but also reveal that behavioural dominance does not equate to reproductive dominance under all conditions.
Worker reproductive competition affects division of labor in a primitively social paperwasp (Polistes instabilis)
TLDR
It is concluded that worker reproductive competition may have influenced the evolution of colony organization in social insects and that worker interactions play a strong role in regulating task performance.
Reproductive plasticity in bumblebee workers (Bombus terrestris)—reversion from fertility to sterility under queen influence
TLDR
Egg-laying workers that were introduced into queenless colonies mostly maintained their fertility regardless of colony social phase, which shows that worker transition from cooperative to selfish behavior is reversible depending on the social context.
Experimental analysis of worker division of labor in bumblebee nest thermoregulation (Bombus huntii, Hymenoptera: Apidae)
TLDR
It is concluded that some B. huntii workers specialize on nest thermoregulation, and that changes in work rates are more important than task switching in meeting thermal challenges.
Reproductive potential and its behavioural consequences in orphaned bumblebee workers (Bombus impatiens)
TLDR
The results challenge the premise that aggression is a means of preventing reproduction by kin: aggression may possibly serve to promote it.
Competition and cooperation: bumblebee spatial organization and division of labor may affect worker reproduction late in life
TLDR
It is suggested that inactive bumblebees may be storing fat reserves to later develop reproductive organs and that the spatial organization of workers inside the nest, particularly the distance workers maintain from the queen, may predict which individuals will later have the greatest reproductive potential in the colony.
The Relationship of Weight and Ovarian Development in Bombus terrestris L. Workers under Different Social Conditions
TLDR
The observations indicate that the presence of a queen does not inhibit the ovarian development of workers, and there was a positive correlation between the weight and the ovarian developmental status of workers in groups containing 8 workers.
Comparative Analysis of Worker Reproduction and Policing in Eusocial Hymenoptera Supports Relatedness Theory
TLDR
This analysis provides strong overall support for the theory that relatedness affects kin conflict over male parentage and shows that a significantly higher percentage of the males are workers’ sons in species where the workers are more related to other workers' sons.

Individual and colony factors in bumble bee division of labor (Bombus bifarius nearcticus Handl; Hymenoptera, Apidae)
TLDR
It is concluded that rates of performing some tasks were largely determined by changes in colony demography or correlated variables, while rates of performance of other tasks depended more on external environmental conditions.
Can alloethism in workers of the bumblebee, Bombus terrestris, be explained in terms of foraging efficiency?
TLDR
This work established whether workers of the bumblebee, Bombus terrestris (L.) (Hymenoptera; Apidae), exhibit alloethism, and quantified the size of workers engaging in foraging compared to those that remain in the nest, and confirmed that it is the larger bees that tend to forage.
Size variation and foraging rate in bumblebees (Bombus terrestris)
TLDR
Examination of size-dependent interindividual variability in foraging in bumblebees found large foragers contributed disproportionately more to the current nectar influx of their colony.
Development and reproductive strategies in Bombus terrestris colonies
TLDR
The development and the reproductive output of 26 Bombus terrestris colonies were investigated and the loss of dominance by the queen was expressed by the beginning of aggression on the part of queen and workers, worker oviposition, oophagy and the functional elimination of the queen.
Investigations Into the Regulation of Dominance Behaviour and of the Division of Labour in Bumblebee Colonies (Bombus Terrestris)
TLDR
It is concluded that a Bombus terrestris colony is a stable social structure, in which the dominance of the queen and colony needs for food determine the differentiation in foragers or house bees, some of which will become egglayer.
Worker age, size and social status in queenless colonies of the ant Leptothorax gredleri
TLDR
This work investigated what proximately determines a worker's social status in queenless colonies of the ant Leptothorax gredleri and found high-ranking individuals were more active and had greater ovarian development than their low-ranking nestmates.
Thresholds of Response in Nest Thermoregulation by Worker Bumble Bees, Bombus bifarius nearcticus (Hymenoptera: Apidae)
TLDR
It is found that worker bumble bees (Bombus bifarius nearcticus) responded to changes in ambient temperature by altering their rates of performing two tasks - wing fanning and brood cell incubation, which are consistent with a threshold of response model for thermoregulatory behavior of B. bifarian workers.
Reproductive Harmony via Mutual Policing by Workers in Eusocial Hymenoptera
TLDR
Examination of the cause-effect relationship between queen mating frequency and worker policing indicates that worker policing is caused by queen polyandry but thatworker policing is unlikely to cause polyandries, although it may help stabilize it if police workers show behavioral dominance.
Dominance and polyethism in the eusocial wasp Mischocyttarus mastigophorus (Hymenoptera: Vespidae)
TLDR
It is hypothesized that changes in polyethism were enabled by the evolution of increased colony size in the Epiponini, and that dominance interactions do not regulate forager specialization or task partitioning in epiponines.
Worker biting interactions and task performance in a swarm-founding eusocial wasp (Polybia occidentalis, Hymenoptera: Vespidae)
TLDR
Evidence that social biting affects task performance without direct reproductive conflict in Polybia occidentalis, a swarm-founding eusocial wasp is presented, and patterns suggest that social bitten influences foraging rates by increasing workers’ probabilities of leaving the nest.
