In recent years the honey bee industry has been experiencing increased loss of hives. The accumulation of multiple stressors on a hive potentially drives hive loss in various ways, including winter loss and colony collapse disorder. One of these stressors is the breakdown of thermoregulation inside the hive. For pupae to develop correctly into healthy adult bees, the temperature within the hive must be regulated by the hive bees to within a narrow range that ensures optimal development. Suboptimal development in adults affects their brain and flight muscles so bees becomes inefficient foragers with shorter life spans. We model the effect of thermoregulation on hive health using a system of delay differential equations that show that thermoregulatory stress has the capacity to drive colony loss in the model via a saddle-node bifurcation with an associated Allee effect.

蜂巢温度调节不良会产生Allee效应,并导致菌落崩溃。

近年来,蜜蜂工业一直在遭受蜂箱损失的增加。多个压力源在蜂巢上的积累可能以各种方式驱动蜂巢损失,包括冬季损失和菌落崩溃障碍。这些压力因素之一是蜂巢内部温度调节的破坏。为了使p正确发育成健康的成年蜜蜂,蜂巢内的温度必须通过蜂巢蜂调节到确保最佳发育的狭窄范围内。成年动物发育欠佳会影响他们的大脑和飞行肌肉,因此蜜蜂成为低效的觅食者,寿命较短。
