A Closer Look: COLONY STRESS

摘要

"The biological concept of stress originated in mammals. The concept of stress is useful in understanding the physiological and behavioral responses of honey bees to harmful situations. There are three stages to an organism's acute stress response: itfirst detects the stressor with sensory organs, then responds to it by defense or escape. Finally, if the stressor cannot be avoided and is sustained, the organism enters a state of exhaustion. Physiological response mechanisms to stress in insects haverecently been studied. Such responses involve biogenic amines (octopamine, dopamine), neuropeptides (allatostatin corazonin) and metabolic hormones (adipokinetic hormone, diuretic hormone). Even et al. (2012) proposed a hypothetical integrated honey beestress pathway involving the brain, and, particularly the neurohemal organ corpora cardiaca and peripheral targets, including energy storage organs (fat body and crop). They discussed how this system can organize rapid coordinated changes in metabolic activity and arousal, in response to adverse environmental stimuli."
