The current study’s summary of queen quality results compared to the results from previous studies [6,11], including the number of queens tested (n) and the mean (±SD) values of morphometric and mating quality measures. Queens from this study are compared between brood pattern groups, with the queens from 2017 classified by their source colony status (before the exchange) of good-brood or poor-brood.
