摘要： Understanding circadian foraging rhythms activity of the red imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae) foragers at different temperatures is an important step towards developing control measures in Integrated Pest Management (IPM) programs. In this study, the circadian foraging rhythm activities of S. invicta foragersat different temperature were investigated under laboratory and field conditions. Results indicated that the foraging activity increased after sunrise, and maximum foraging occurred at 14:00 (foraging rate was 69.22 +/- 0.57 and 72.58 +/- 1.15 foragers/min in the first and second year, respectively) in the tea fields of Guangzhou during autumn. Furthermore, foragers demonstrated circadian rhythms and exhibited a unimodal after 24 h. A significant correlation was found between foraging activity and temperature. S. invicta colonies were active at moderate soil temperatures (approximately 26.65 degrees C to 29.24 degrees C). The preferred temperature of the colonies was 26 degrees C, followed by 22 degrees C and 18 degrees C in the laboratory. The individual S. invicta activity was maximum at 17:00 (18.67 +/- 1.66 times/10 min) and minimum at 5:00 (8.33 +/- 2.51 times/10 min) at 26 degrees C. The fluctuating temperature had a significant impact on individual locomotor activity (r = 0.8979, P < 0.01) but did not alter the rhythm activity. Our results demonstrated that temperature might play an important role in circadian foraging rhythms activity of S. invicta. These results may have implications for the development of more effective fire ant management strategies. (C) 2020 The Authors. Published by Elsevier B.V. on behalf of King Saud University.
