摘　　要：试验观察荔枝蒂蛀虫Conopomorpha sinensisBradley对寄主植物品种、器官及器官部位的产卵选择性规律。结果表明,与老梢相比,荔枝蒂蛀虫明显倾向于选择嫩梢产卵;4个荔枝品种果枝中以妃子笑上落卵数最多,在淮枝、糯米糍荔枝果实上较少,桂味荔枝上最少;不同的荔枝品种果实气味引诱雌虫产卵的能力不同,其中妃子笑引诱力最强,淮枝、糯米糍引诱力较低,桂味最低;在同一荔枝果实不同部位的落卵量,以果皮上、下两部分较大,全果明显低于果皮上部,而荔枝肉和荔枝核上没有落卵。The attracting effect of different parts of host plants litchi and longan （ Litchii chinensis Sonn and Euphoria longana Lam） on oviposition of litchi fruit borer Conopomorpha sinensis Bradley was studied in this paper. The results showed that females only selected and oviposited at the new sprigs when only new and old sprigs were provided. Females liked to select Feizixiao mostly, Huaizhi and Luornizi secondary, Guiwei least when fruits of four litchi varieties were provided. The attraction of different litchis varieties fruits to the females was different, and Feizixiao was strongest, Huaizhi and Luomizi secondary, and Guiwei least. Number of eggs was significantly different at the different parts of the litchi fruit.
