【摘要】 通过无水无食、无水有食和有水无食3种处理方法,对橘小实蝇Bactrocera dorsalis(Hendel)广西南宁、广东广州、福建福州和湖北武汉等4个地区种群不同日龄成虫的耐饥渴能力进行了比较。结果表明:橘小实蝇5日龄成虫的耐饥渴能力强于1日龄和10日龄的成虫,1日龄的耐饥渴能力最低;1日龄、5日龄、10日龄成虫在无水有食条件下的平均存活时间均长于有水无食和无水无食处理下的平均存活时间;广东广州种群5日龄和10日龄成虫的耐饥渴能力显著高于其他3个种群。更多还原

【Abstract】 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.更多还原
