摘　　要：通过枣实蝇产卵选择习性研究,发现枣实蝇喜欢产卵于枣果的背阴面及底部,其产卵孔周围呈现凹陷或瘤状凸起症状,且对不同品种枣果的产卵选择性不同,‘鸡心枣’、‘骏枣’对枣实蝇的抗性大于‘梨枣’、‘灰枣’和‘相枣’;枣果受伤害程度越重,产卵量就越少;不同大小的枣果均受到危害,且以中型果受害最为严重;随枣果成熟度的增加其产卵量逐渐减少,且不产卵于完全红的枣果上。同时枣实蝇对枣、海棠果、青杏、番茄、葡萄等不同寄主的产卵选择性均存在显著性差异,但更喜欢产卵于枣果。胁迫性寄主试验中不同寄主果实的产卵量存在显著差异,但枣果与杏之间的产卵量差异不明显,而且枣实蝇可以在杏果中化蛹并羽化。The ber fruit fly Carpomya vesuviana Costa preferred to oviposit on the shades and bottom of jujube based on our study on oviposition preference. The oviposition aperture showed hollow and lump-like shapes. It was showed that the ber fruit fly had different ovipositional selection to different varieties of jujube. The ＇Jixinzao＇ jujube and ＇Junzao＇ jujube were less severely damaged than ＇pear jujube＇, ＇grey jujube＇ and ＇Xiang jujube＇. It ovipositional selection decreased as the extent of damage increased. The ber fruit fly＇s harms to the jujube differed depending on jujube size. The medium-sized jujube was more hurtful than others. Its ovipositional selection decreased as the maturing stage of the jujube increased. The bet fruit fly showed no ovipositional selection at full maturity. The jujube was more hurtful than others and had significant difference in oviposition preference for jujube, Beijing flowering crab, apricot, tomato and grape. No significant difference existed between jujube and apricot, but significant difference existed in oviposition preference between different species of hosts. The ber fruit fly could pupate and eclose on the apricot.
