IN most species of social Hymenoptera with queen–worker dimorphism, workers cannot mate but retain functional ovaries1; because males arise from unfertilized haploid eggs, workers can potentially produce males. Worker-derived males are frequent in some species, but in others occur only in queenless colonies2,3. Workers are more related to their own sons (coefficient of 0.5) than to the queen's sons (their brothers; 0.25); they are also more related to nephews (0.375) than brothers if queens… 
No facultative worker policing in the honey bee (Apis mellifera L.)
TLDR
Test and reject the hypothesis that workers in single-patriline colonies prefer worker-derived males and are able to reproduce directly, and show that their eggs are policed as strongly as those of workers in colonies with multiply mated queens.
Worker policing in the European hornet Vespa crabro
TLDR
The presence of worker policing in queenright hornet colonies provides a proximate explanation for the absence of worker reproduction and may have been selected for because it enhances colony productivity by eliminating costly conflicts over reproduction.
Why do honey bee workers destroy each other’s eggs?
TLDR
Evidence indicating that worker-l laid eggs may be much less viable than queen-laid eggs opens up the possibility that worker policing may simply be a matter of destroying dead eggs and rearing live ones, which raises serious doubts about the widely accepted relatedness based argument for the evolution of worker policing.
Male parentage in army ants
TLDR
Comparing worker genotypes and inferred queen genotypes from the same colonies show that workers do not or at best very rarely reproduce in the presence of the queen, which implies that workers are on average more closely related to queen sons than to other workers’ sons.
CONFLICTS OF INTEREST IN SOCIAL INSECTS: MALE PRODUCTION IN TWO SPECIES OF POLISTES
TLDR
For two species of Polistes, DNA microsatellites were used to estimate two relatednesses, to determine the sex of brood, and to determine whether male brood was produced by queens or workers, which results do not support collective worker control.
Male production in stingless bees: variable outcomes of queen–worker conflict
TLDR
The method of estimating worker male production appears to be more accurate than exclusion, which sometimes underestimates the proportion of males that are worker produced, and this prediction is borne out in honey bees.

TLDR
Worker policing in V.vulgaris may be selected due to the colony–level benefit of conflict suppression, and genetic analysis revealed that workers are equally related to the queen's and other workers' sons.
Reproduction of rebel workers in honeybee (Apis mellifera) colonies
TLDR
This work shows for the first time that rebel workers not only activate their ovaries but also produce significantly more male offspring in queenright colonies than do normal workers, and shows that the level of rebel reproduction in queen right colonies is similar to the reproduction of normal workers in queenless colonies.
Worker reproductive parasitism in naturally orphaned colonies of the Asian red dwarf honey bee, Apis florea
TLDR
It is shown that WRP is present in orphaned colonies, andNon-natal workers have significantly higher rates of ovary activation than natal workers, and natal and non-natals had statistically equal reproductive success, but this may have been due to the small number of non-Natals present.
Egg viability and worker policing in honey bees.
TLDR
It is shown that in queenright honey bee colonies (Apis mellifera), worker reproduction is low, and that this difference in quality is the case for honey bees.

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.

TLDR
The analysis of data assembled on 49 ant species reveals that workers in monogynous species (i.e., with one queen per colony) reproduce moslty in queenless conditions, whereas those in polygynous species reproduce in queensless and queenright conditions equally often, in agreement with kinship theory.
Haploidploidy and the evolution of the social insect.
TLDR
Evidence is presented from 20 species that the ratio of investment in monogynous ants is, indeed, about 1 : 3, and this discovery is subject to a series of tests, which provide quantitative evidence in support of kinship theory, sex ratio theory, and the assumption that the offspring is capable of acting counter to its parents' best interests.
Caste and ecology in the social insects.
TLDR
In this pathbreaking and far-reaching work George Oster and Edward Wilson provide the first fully developed theory of caste evolution among the social insects and construct a series of mathematical models to characterize the agents of natural selection that promote particular caste systems.

TLDR
With better knowledge of heredity and with more facts regarding the social insects to draw upon, Weismann recognized the possible conflict between intergroup and intragroup selection in the evolution of worker attributes.
Forceps Design for Transferring Honey Bee Eggs
TLDR
Forceps modified from ordinary dissecting forceps can be used Successfully to move eggs of any age of the honey bee ( Apis mellifera L.) and about 75% hatch of the eggs transferred may be expected whether they are developed inside the hive or in the incubator.
