Bumblebees play an irreplaceable role in the pollination of wild plants and greenhouse crops.Ambient temperature is an important factor affecting the pollen and nectar collection of bumblebees.However,little is known about the influence of ambient temperature on the foraging and flower-visiting behavior of bumblebees.In this study,radio frequency identification(RFID)technology was used to monitor the foraging behavior of Bombus terrestris in Shihezi area of Xinjiang in July 2023.The flower-visiting behavior of the workers was manually observed during three periods:10:00～11:00,16:00～17:00 and 20:00～21:00.The results showed that the foraging time of worker for each bout decreased with the temperature increasing(between 23.3℃ to 38.8℃).The foraging time for each flower(6.43±0.48 s)during 10:00～11:00 was significantly lower than in 16:00～17:00 and 20:00～21:00(9.79±0.79 s and 10.82±1.05 s),this results indicated that the foraging time for each flower increased with the ambient temperature increasing.Accordingly,the visiting frequency of workers during 10:00～11:00(9.74±0.51 times/min)was significantly higher than that during 16:00～17:00(7.56±0.56 times/min).Further analysis showed that the visiting frequency of worker bees decreased with the ambient temperature increasing.
