Queen cell destruction

During swarming, emergency queen rearing and supersedure excess of queen cells is produced. Many of the queen cells are destroyed before queens emerge from them. The queen cells can be destroyed either by queens or workers.

Most of capped queen cells are destroyed by young queens. They patrol the nest in search of queen cells to kill rival queens while they are vulnerable. After discovering a queen cell young queen starts to move faster and its body (especially thorax) temperature increases markedly [1]. The queen cuts a small hole in the side wall of the queen cell [2] (which can take 35 minutes [3] from [4]) and stings unemerged queen [5] but see [2]. Destruction of the queen cell is completed by workers [2]. The queen can perceive presence of unemerged queens thanks to both pheromones and comb vibrations [6]. The queen first destroys queen cells just before emergence and later destroys queen cells with younger brood [2][4][7]. By doing this she minimizes risk that other queens emerge during destruction of consecutive queen cells. There is a range of substances which can be used by queens to perceive presence and age of unemerged queens [8][9][10][11]. The queen which first emerged often is not able to destroy all queen cells before other queens emerge from them [12] and queen fighting occurs. Workers can prevent queens from destroying queen cells by aggressive behaviour [13][14].

Queens cells can be also destroyed by workers. During emergency queen rearing significant proportion of uncapped queen cells is destroyed by workers about five days after dequeening [12]. Also during swarming many of the initiated queen cells are destroyed by workers before or after capping [13][15]. It is possible that workers remove this way unhealthy and improperly developing brood. Workers often destroy queen cells during unfavourable weather [5][16]. Unlike in queenright colonies, where queen cells with holes are destroyed, in queenless colonies they are repaired by workers [2].
