The tolerance of starvation and thirstresistance of four field collected(Nanning Guangxi,Guangzhou Guangdong,Fuzhou Fujian,Wuhan Hubei),geographical populations of oriental fruit fly,Bactrocera dorsalis(Hendel), were compared. Three treatments were set in the experiment: providing water without food,providing food without water and providing no water and food.The results show that the adult males and females,aging 5-days,had stronger tolerance than those of aging 1-day and 10-days, while the tolerance of starvation and thirstiness resistance of those at the age of 1-day was the lowest. The average survival time of the adults at the age of 1-day, 5-days and 10-days under the treatment of providing food without water is longer than those with the treatment of providing water without food. The tolerance of starvation and thirstiness resistance of the adults at the age of 5-days and 10-days from Guangzhou Guangdong population is higher than those of the other three geographical populations.
