真社会性蜜蜂种群(Apis mellifera)采用卵、幼虫、蛹、蜂巢蜂和觅食蜂的年龄分层组织。了解最近蜂群数量的下降取决于了解影响这些不同年龄种姓的因素。我们首先对稳态蜜蜂种群进行分析,考虑到每个蜂种内的死亡率,发现蜜蜂群体非常容易受到蜂巢和蛹死亡率的影响。随后,我们通过 Schmickl、Crailsheim 和 Khoury 等人建立的模型基础来研究瞬时蜜蜂种群动态。我们基于微分方程的瞬态模型解释了信息素对减缓蜂巢蜜蜂成熟到觅食蜜蜂的影响、在缺乏足够蜂巢的情况下幼虫死亡率增加以及食物短缺的影响。我们还进行敏感性研究并显示参数变化对菌落群体的影响。
Eusocial honey bee populations (Apis mellifera) employ an age stratification organization of egg, larvae, pupae, hive bees and foraging bees. Understanding the recent decline in honey bee colonies hinges on understanding the factors that impact each of these different age castes. We first perform an analysis of steady state bee populations given mortality rates within each bee caste and find that the honey bee colony is highly susceptible to hive and pupae mortality rates. Subsequently, we study transient bee population dynamics by building upon the modeling foundation established by Schmickl and Crailsheim and Khoury et al. Our transient model based on differential equations accounts for the effects of pheromones in slowing the maturation of hive bees to foraging bees, the increased mortality of larvae in the absence of sufficient hive bees, and the effects of food scarcity. We also conduct sensitivity studies and show the effects of parameter variations on the colony population.
