【摘要】 大黄袍是叶色特黄的黄化茶树新品种。黑刺粉虱（Aleurocanthus spiniferus）成虫嗜好趋向于叶色鲜亮、黄色色度偏高的大黄袍品种，喜在晨昏时分聚集于茶树芽梢上交尾、追逐、产卵、刺吸、分泌和休息等。为揭示其趋性机制，以顶空取样法采集大黄袍种苗挥发物，鉴定出20种化合物；以Y-管嗅觉仪测定黑刺粉虱行为，发现其中水杨酸甲酯、芳樟醇、顺-3-己烯-1-醇、正己醇和反-2-己烯醛显著吸引该粉虱成虫。在温室内静息环境中，携带等比例的这5种信息化合物诱饵的大黄袍种苗模型显著地吸引飞行中的黑刺粉虱成虫。研究结果表明，这5种信息化合物与大黄袍枝叶的金黄色的组合诱导了黑刺粉虱成虫的定位和着陆。更多还原

【Abstract】 ‘Dahuangpao’ is a yellowing new tea elite cultivar with special yellow foliage. The adults of spiny citrus whitefly, Aleurocanthus spiniferus, is keen on flying to tea cultivars whose leaf color is bright and shining with yellow chroma being slightly high. Especially, the whiteflies preferred to directionally fly to and gather on ‘Dahuangpao’ tea shoots for mating, chasing, oviposition, piercing and sucking sap, secreting and resting. In order to reveal its taxis mechanism, the volatiles of the tea seedlings were collected by headspace aeration sampling method from which twenty compounds were identified. Among them methyl salicylate, linalool, cis-3-hexen-1-ol,n-hexanol and tran-2-hexenal significantly attracted the adults of the whiteflies in a Y-tube olfactometer bioassay,respectively. Within resting habitat in greenhouse, ‘Dahuangpao’ tea seedling models baited by the five infochemicals at equal ratio intensely attracted the adults in flight. This study demonstrated the five volatile compounds from ‘Dahuangpao’ tea seedlings were strongly attractive to the adults. And the combination of these volatiles with the special yellow leaf colour, and the shape of tea plants resulted in orientation and landing of adults onto ‘Dahuangpao’ tea plants.更多还原
