摘　　要：【目的】为探究饥饿和饥渴条件对柑橘大实蝇Bactrocera minax成虫活动能力的影响。【方法】本文对1日龄和10日龄柑橘大实蝇在饥饿饥渴下的成虫活跃度和驱上爬行能力进行分析。【结果】无水无蜜条件下柑橘大实蝇1日龄和10日龄雌雄成虫爬行虫比例均最高,显著高于供水供蜜。其中1日龄雌成虫遭受饥饿饥渴胁迫后,其活动能力受影响更大,成虫爬行虫比例和单虫上行高度增幅均较10日龄雌成虫大。雌雄成虫之间爬行虫比例、单虫上行高度无差异。【结论】饥饿和饥渴下柑橘大实蝇成虫的活动力更强,尤其是新羽化的成虫。这使得成虫潜在的扩散概率提高,促进其出园觅食。[Objectives] To investigate the effects of hunger and thirst on the activity of adult B. minax.[Methods] The ratio of active to inactive insects, and the height climbed by individual insects on day 1 and day 10 of the experiment, were measured and compared in a group of insects deprived of food and water and a control group provided with food and water.[Results] The ratio of active to inactive insects was significantly higher in the deprived group than in the control group.Females in the deprived group climbed significantly higher on day 1, and the ratio of active to inactive insects, and height climbed per insect, were higher than control females on day 10. There was no significant difference in the ratio of active to inactive insects and the height climbed per insect between males and females.[Conclusion] Starvation and thirst can increase the activity and potential dispersal range of adult B. minax.
