Thus, in the first year of this project, we will continue the experiments proposed in the Phase-I project, a large uniform magnetic generator will be developed to perform electrophysiology experiments for identifying the electrophysiological signals, the conducting path of the signals, as well as to determine the positions of the ferromagnetic magnetoreceptors in honeybees. In addition, by cooperating with other subprojects, several experimental devices will be designed in this subproject to investigate the change of the magnetic navigation and flying capability of honeybees under different treatments, health, infected by Nosema ceranea, as well as poisoned by insecticides. Thus, a mobile laser marking device will be utilized to analyze the entering and leaving activities of tagged honeybees in hives. Furthermore, this study is also planned to analyze the activities of all honeybees by installing infrared-based automatic counting pathways to the hives. In the second and third years, a flying capability evaluation system, that consists of force sensors, torque sensors and infrared photosensors, will be developed to examine the flying capability of honeybees when they receive visual or air flow stimulations. In the third year, the flying evaluation system will be improved using computer-aided automatic control system to reduce potential experimenter’s bias due to human factors.蜜蜂磁導航電生理實驗行為學實驗磁場產生器飛行能力評估honeybeemagnetic navigationelectrophysiology experimentsbehavior experimentsmagnetic generatorflying capability evaluation
