The influence of queen age and quality during queen replacement in honeybee colonies

Animal Behaviour, 2000
Honeybee, Apis mellifera, colonies replace their queens by constructing many queen cells and then eliminating supernumerary queens until only one remains. The ages of the queens and the variation in their reproductive potential are important factors in the outcome of such events.

Effect of queen quality on interactions between workers and dueling queens in honeybee ( Apis mellifera L.) colonies

Behavioral Ecology and Sociobiology, 2003
The fitness of a social insect colony depends greatly on the quality (i.e., mating ability, fecundity, and offspring viability) of its queen(s). In honeybees, there is marked variation in the quality of young queens that compete in a series of lethal duels to replace a colony’s previous queen.

Worker regulation of emergency queen rearing in honey bee colonies and the resultant variation in queen quality

Insectes Sociaux, 1999
The requeening process was investigated under emergency conditions in honey bee colonies (Apis mellifera L.). The progression of queen cell construction was closely monitored after removal of the mother queen, and the newly-emerged queens were measured for several physical traits to quantify their reproductive potential (= quality). The results suggest

The quality of Gold Queen Hami melons stored under different temperatures

Scientia Horticulturae, 2019
Abstract Low temperature storage prolongs the postharvest life of various fresh fruits and vegetables. However, the actual storage temperature may also significantly influence fruit and vegetable quality. In the present study, we stored Gold Queen Hami melons at three different temperatures [21 °C (control), 3 °C, and 0.5 °C (0 ± 0.5 °C)] for 36 days.

Honeybee queen quality control in Croatia

2012
Honeybee queen quality control is estimated by monitoring of spermatheca morphological characteristics. Three queens were taken from 28 Croatian queen breeders. The quality control was carried out on Croatian native honeybee queens (Apis mellifera carnica). Diameter of spermatheca and number of spermatozoa were analyzed.
