从两个蜜蜂种群育雏研究的数据表明，一个稳定的群体群体投资性比存在的蜜蜂。由于群体繁殖的分裂模式，这种投资比例最好用生殖雄性（雄蜂）生物量和不育工蜂生物量的平均群体生产来表示。根据Fisher（1930）的性比假说，提出了一个种群投资性比的初步模型，该模型考虑了蜂群季节性雄蜂和工蜂的生产，并建议两个种群的性比趋于1：1。在第一项研究中，在一年中不产生生殖雌性的菌落平均每个菌落产生18，969 ± 7，267（± SD，n = 7个菌落）雄性，另一项研究中为22，560 ± 8，280（n = 13个菌落）。第二项研究中的三个菌落确实产生了生殖雌性，并进行了菌落分裂。这些殖民地在裂变发生之前平均产生了20，856 ± 4，241名男性。一个孤蚁群在死亡前产下了6,161只雄蚁。
Data from two honey bee population brood-rearing studies suggest that a stable populational colony investment sex ratio exists for the honey bee. As a consequence of the fissioning mode of colony reproduction, this investment ratio is best expressed in terms of the average population production of reproductive male (drone) biomass and the biomass of sterile workers. A tentative model for a populational investment sex ratio based on Fisher's (1930) sex ratio hypothesis is presented in terms of colony seasonal drone and worker brood production and suggests a ratio for both populations tending toward 1:1. Colonies that produced no reproductive females during an annual season produced an average of 18,969 ± 7,267 (± SD, n = 7 colonies) males per colony for the first study and 22,560 ± 8,280 (n = 13 colonies) for the other. Three colonies from the second study did produce reproductive females and underwent colony fission. These colonies produced an average of 20,856 ± 4,241 males before fissioning occurred. One orphaned colony produced 6,161 males before it died.
