摘　　要：【目的】研究枣实蝇在寄主植物果实不同发育期的危害程度对其最佳防治期。【方法】分析枣园对不同寄主枣树样枝套袋枣实蝇的蛀果率,调查虫口密度;室内饲养测定果实不同发育期对枣实蝇生长发育和繁殖的影响,分析和评价枣实蝇对不同发育期骏枣和酸枣果实的生物学响应变化。【结果】枣实蝇对骏枣果实的蛀果率均大于对酸枣的蛀果率,并且枣实蝇在骏枣果实成熟期蛀果率为最大;成熟期骏枣上的虫口密度也最大;骏枣上雌虫产卵痕数、幼虫数和卵的孵化率均大于酸枣上的枣实蝇。在枣果着色期和成熟期,蛹的各项生长指标均高于膨大期;果实不同发育期,骏枣上的蛹各项生长指标均显著大于(P<0.05)酸枣上的;骏枣上枣实蝇的蛹期、雌虫怀卵量、性成熟历期、交配时间以及雌雄成虫寿命均略大于酸枣,但无显著差异(P>0.05)。【结论】枣实蝇对骏枣的选择性强于酸枣,并且成熟期的骏枣果实更适宜枣实蝇生长发育。【Objective】It is of great significance to determine the optimal control period of Carpomya vesuviana Costa for the damage degree of jujube fruit in different development stages.【Methods】The boring rate and insect density of C.vesuviana in jujube orchard were observed by bagging samples of different hosts.At the same time,the effects of different stages of fruit development on the growth,development and reproduction of C.vesuviana were measured indoors.Also,the biological response of Ziziphus jujubavar.spinosa and Junzao to fruits in different developmental stages was analyzed and evaluated.【Results】The boring rate of Junzao was higher than that of Ziziphus jujuba var.spinosa.The boring rate was the highest in the mature stage of Jujube fruit.The density of insect on jujube was the highest at the mature stage.The number of oviposition marks,larvae number and egg hatching rate of the female on Junzao were all higher than that on the Ziziphus jujuba var.spinosa of C.vesuviana.The growth indexes of pupa were higher than those of jujube fruit in coloring and maturing stage.At different stages of fruit development,the growth indexes of pupa on Junzao were significantly higher than those on Ziziphus jujuba var.spinosa.The pupa stage,egg amount of female,sexual maturity period,mating time and male and female adult life span of Junzao were slightly higher than that of Ziziphus jujuba var.spinosa,but there was no significant difference(P>0.05).【Conclusion】The selectivity of C.vesuviana to Junzao was stronger than that of Ziziphus jujubavar.spinosa,and the fruit of Junzao at mature stage was more suitable for the growth and development of C.vesuviana.
