Abstract：[Objectives] To improve understanding of the migratory biology of Calliptamus italicus (L.) , and the ability to forecast outbreaks of this pest, by determining its flight ability. [Methods] We studied the relationship between flight capacity and age and between flight capacity and ovarian development, in a flight mill from June to September in 2014. [Results] During daylight hours (8 am. to 8 pm.), female adults started to fly at 2 days old. Their flight capacity improved significantly (P<0.05) until they were 6 days old, reaching maxima of 18.22 min flight time, 231.01 m flight distance, 12.59 m·min-1 in speed and 76.00 % of number engaged in flight. Flight ability decreased from 6 to 10 days of age. Male adults maximal flight statistics were; 0.64 min flight time, 13.34 m flight distance, 15.70 m·min-1 speed and 14.29 % of time engaged in flight. Male flight ability decreased from 2 to 10 days of age. Flight capacity varied significantly with age and ovarian development in female adults, among which 6 day old females adults had the strongest flight capacity (P<0.05). [Conclusion] Adults of the Xinjiang population of C.italicus have considerable flight ability.
