摘要
通过对桔小实蝇自然种群田间系统调查和室内实验种群的饲养观察,组建了以作用因子组配的桔小实蝇在不同寄主上的自然种群生命表.结果表明,桔小实蝇在青枣、杨桃、枇杷、柑桔、番石榴和芒果上的种群趋势指数分别是91.5、103.5、120.8、127.3、172.2和183.8.表明在这些果园中,桔小实蝇的种群密度是上一代的91.5～183.8倍.在果园中,'捕食及其它'因子是影响桔小实蝇种群数量发展的重要因子,其幼虫期在青枣、杨桃、番石榴、芒果、枇杷、柑桔上的排除作用控制指数分别为2.907、2.618、2.591、2.415、2.193和1.866.
Based on the investigating data of population in laboratory and field,the life table of Bactrocera(Bactrocera) dorsalis (Hendel) was constructed with the affecting factors in different hosts.The results showed that the index of population developmental trend(I) of B. dorsalis in Zizyphus mauritiana,Averrhoa carambola,Eriobotrya japonica,Citrus reticulate,Psidium guajava and Mangifera indica were 91.5,103.5,120.8,127.3,172.2 and 183.8 respectively.The factor “predator and other”was important on population development of B. dorsalis,the exclusive index population control(EIPC) of “predator and other” were 2.907,2.618,2.591,2.415,2.193 and 1.866 in the host of Z. mauritiana,A. carambola,P.guajava,M. indica,E. japonica and C.reticulate respectively.
