Beta frequently used as rootstock in China was susceptible to phylloxera. Phylloxera survived at 38.82%~47.5% and produced 9.01 eggs per day on Beta, while the corresponding values were 25%~30% on concord and compbell and 6.00~6.85 eggs per day on concord, campbell and catawba. Both Hei Huxiang and White Banana of Vitis vinifera-V. amerancain were susceptible to phylloxera, on which phylloxera yielded more than 190 eggs totally despite their survival was down-regulated and development arrested to some extent. All V. vinifera and cross cultivars of V. vinifera-V.

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.

為了檢測我國葡萄品種和砧木對中國生態(tài)型葡萄根瘤蚜Daktulosphaira viticola的抗性，在實(shí)驗(yàn)室條件下采用離體根接種法鑒定了10個(gè)葡萄砧木337啪啪肉体、18個(gè)葡萄栽培品種欧美一级男女插穴视频，測定了根瘤蚜存活率、發(fā)育歷期免费2级黄网站、產(chǎn)卵量亚洲国产美女精品综合久久、種群齡期結(jié)構(gòu)指數(shù)和成蟲大小等指標(biāo)。

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'.

Results showed that the rootstocks RSB, Gravesac, 520A and 225R were immune to phylloxera infestation. Fercal, 1613C and the HPDs was resistant to phylloxera to some extent, whose tuberosities % were less than 27%. The Both Henan wild grapes and V. adenocluda were highly sensitive to phylloxera,whose tuberosities were 66.25% and 56.67% and phylloxera produced 181.67 and 277.67 eggs on each of them; V.guangxi-quinquangularis had low resistance, whose tuberosities were 15.45%, its hybrid with a V.vinifera variety NW196 was sensible to phylloxera, whose tuberosities and egg number phylloxera produced were 46.13% and 55.28% higher than V. guangxi-quinquangularis.
