摘要
角倍蚜虫夏寄主盐肤木物候期观察研究结果表明：坡向对物候期影响较大，不同坡向盐肤木的萌芽、展叶、开花、结实、落叶等物候现象存在一定程度的差异，出现最早的是南坡，最迟的基本上是北坡．福建南平适宜引种放养角倍蚜虫的展叶期是３月下旬至４月上旬；展叶早、速度快、历期短的是南坡，历期仅１０天，于３月底结束；历期较长的是东坡，约２０天，展叶盛期可持续到４月上旬；放养排序为：南坡＞山凹＞西坡＞北坡＞东坡．
Aspect revealed an important effect on phenological phase of Haloxylon ammodendron parasitized by aphids. Significant differences in bud break, leaf expansion, flowering, fruiting and leaf falling ofHaloxylon ammodendron existed between the aspects, with earliest sprouting in the southerly aspect, and latest in the northerly aspect. The fresh leaves expanded from the late period of March to the early period of April were suitable for feeding aphids in Nanping, Fujian Leaf expansion lasted only 10 days in southerly aspect, and 20 days in easterly aspect. Breeding capacities for the aphids decreased in the order: southerly aspect >moutain valley>westerly aspect>northerly aspect>easterly aspect.
