药用菊花对菊花瘿蚊的抗性研究

The Resistance of Medicine Chrysanthemum to Chrysanthemum Gall Midge

以单株虫瘿量作为指标就我国常见的14种药用菊花对菊花瘿蚊的抗性进行鉴定,结果表明,祁菊为高感品种;怀小白菊、小亳菊为感虫品种;温茶菊、杭菊、大亳菊、贡黄菊为抗虫品种;贡白菊及3种野菊花等为高抗品种。抗性机制研究表明,菊花瘿蚊对不同菊花资源的产卵存在选择性差异。各菊花品种瘿蚊蛹重差异不大,但死亡率差异较大,存在抗生性差异。

The resistance of traditional Chinese medicine chrysanthemum to chrysanthemum gall midge （Epimgia sp. ） was examined in the field based on the gall number. The Qiju from Hebei province was highly susceptible. The little Huaibaiju from Henan province and the little Boju from Anhui province were susceptible. The Hangju from Zhejiang province and the yellow Gongju from Anhui province were resistant to the insect. The white Gongju from Anhui and three wild species were highly resistant. The chrysanthemum gall midge showed ovipositional preference to some susceptive varieties. There was no significant different in the weight of pupae fed on different varieties of chrysanthemum. The mortality of the larvae on different varieties of chrysanthemum were different, showing the exist of larval antibiosis.
