The grape is the fruit preferences, but serious grape phylloxera, has been identified as the main quarantine objects at home and abroad.

葡萄是人们喜好的水果之一，但葡萄根瘤蚜危害严重，已被列为国内外主要检疫对象。

Research on the occurrence of grape phylloxera symptoms, pathogen characteristics, infection process, the occurrence of the conditions, as well as control methods, thereby enhancing the production of grapes.

研究葡萄根瘤蚜发生的症状、病原特征、侵染过程、发生条件、以及防治方法，从而提高葡萄的产量。

In this study, laboratory bioassays were carried out for rapid initial evaluation on the resistance of 10 grape rootstocks and 18 cultivars to Chinese biotypes of grape phylloxera, Daktulosphaira viticola. The survival ratio, developmental duration, egg number and index for population age constitution were evaluated.

为了检测我国葡萄品种和砧木对中国生态型葡萄根瘤蚜Daktulosphaira viticola的抗性，在实验室条件下采用离体根接种法鉴定了10个葡萄砧木、18个葡萄栽培品种，测定了根瘤蚜存活率、发育历期、产卵量、种群龄期结构指数和成虫大小等指标。

To probe into either the attractiveness to or avoidance from phylloxera of grape rootstocks and cultivars with different tolerance, as well as into the volatile components from their roots, the method of invitro root segment culture was used to investigate the selectivity of Phylloxera viticola Fitch to the roots of grape rootstocks '5BB' and '140Ru' and cultivar 'Kyoho'.

为了探讨不同抗性水平砧木及品种对根瘤蚜吸引及驱避效应以及鉴定挥发性物质组分，采用离体根段培养法测定葡萄根瘤蚜Phylloxera viticola Fitch对砧木5BB，140 Ru及栽培品种巨峰的选择性，发现根瘤蚜对栽培品种巨峰的根段具有很强的选择性，至接种后3d，67.13%的根瘤蚜优先选择巨峰；而对5BB和140 Ru的选择性却很差，分别有15.29%和17.58%的根瘤蚜选择5BB及140 Ru。
