摘　　要：本文选择了浙江3种不同杨梅品种,研究了桔小实蝇取食后的生长发育相关5种性状的差异,结果表明,幼虫历期以荸荠种最短,蛹历期和蛹重,水梅值最小;雄成虫东魁最重,并均与另2个杨梅品种差异达显著水平。而幼虫,幼虫-蛹,幼虫-成虫3种存活率,荸荠种最高,水梅最低,二者差异也达显著水平。显然桔小实蝇对不同杨梅品种喜好有所不同,其较为喜好荸荠种,较不喜好水梅。结合果实性状考查结果,不喜好的原因可能与水梅偏酸有关。To investigate the growth and development characters of oriental fruit fly（B.dorsalis） over red bayberry（Myrica rubra） cultivars,three varieties of Zhejiang red bayberry cultivars were tested.The results indicated that Biqi＇s larva duration was the shortest,Shuimei＇s pupa duration and the pupa weight were the smallest;Dongkui＇s male adult weight was the heaviest,and it rearched the significance level with other two varieties of M.rubra cultivars.Among the three varieties of M.rubra cultivars,Biqi＇s survival rates of larva,larva to pupa and larva to adult were all the highest while Shuimei＇s was the lowest and rearched the significance level.The research suggest that B.dorsalis had different performance among different varieties of M.rubra cultivars which shows the Biqi was the favorite cultivars while Shuimei was the least,however,M.rubra was one of the suitable host of B.dorsalis for the similar performance on its favorite host banana.
