Abstract In bumble bees (Bombus) and vespine wasps (Vespa, Vespula, Dolichovespula), workers have regularly been observed to kill their colony's single queen (worker matricide). Workers gain a fitness payoff in worker-produced males from matricide because it removes the queen's inhibition over their reproduction. There is selection for the queen's death when this gain outweighs the fitness penalty of losing queen-derived offspring. A kin selection model explores this condition for three parties…

Using analyses of collected, mature colonies and a surgical manipulation preventing queens from laying female eggs, it is shown that workers do not preferentially kill queens who are only producing male eggs, suggesting a high cost of matricide.
Reproductive physiology, dominance interactions, and division of labour among bumble bee workers
Although worker aggression did not directly affect polyethism, reproductively competent workers avoided foraging tasks that would remove them from egg‐laying opportunities, suggesting that these tasks entail little cost in terms of reproductive competition.
Do queen cuticular hydrocarbons inhibit worker reproduction in Bombus impatiens?
No difference in worker’s ovarian development or egg production is observed when comparing among the mid-season queen extract, late-season queens extract and the solvent control treatments, which is consistent with recent studies showing that queen cuticular compounds do not inhibit worker reproduction in B. impatiens.
Nest wax triggers worker reproduction in the bumblebee Bombus terrestris
It is suggested that wax scent enables workers to time their reproduction by providing essential information concerning the social condition of the colony by changing the patterns and amounts of cuticular lipids change considerably during colony development.
Queen execution in a monogynous ant
Queen expulsion and matricide in a monogynous, monandrous ant with perennial societies led to a significant decrease in the number of workers and brood, but eventually increased the direct fitness of workers through significant male production.
Do hornets have zombie workers?
Colonies of the European hornet, Vespa crabro, are typically founded by a single queen mated to a single male, and it is predicted that strong worker–queen conflict over male production where both the workers and the queen attempt to produce the colony’s males is predicted.
Regulation of worker reproduction in bumblebees (Bombus terrestris): workers eavesdrop on a queen signal
The results are consistent with the hypothesis that workers eavesdrop on the queen pheromones, which allows workers a broader time-window for reproduction and thus to gain fitness from rearing both sister-gynes and sons before the season ends without affecting colony development.

Findings show that the mechanism underlying the queen–worker conflict in insect societies is more complex than previously appreciated and multiple cues are important.
Do Bumble Bee, Bombus impatiens, Queens Signal their Reproductive and Mating Status to their Workers?
It is found that worker ovary activation was inhibited only in the presence of egg-laying queens, regardless of their mating status, indicating that only the presenceof a freely-behaving, egg- laying queen can fully inhibit worker reproduction.
Workers dominate male production in the neotropical bumblebee Bombus wilmattae (Hymenoptera: Apidae)
It is shown that the workers clearly win the queen-worker conflict over male production in B. wilmattae, which sets them apart from the temperate bumblebee species studied so far.
