The DNA fingerprints of 4 biotypes of GM population from 7 locations were analyses by AFLP.Base on the fine mapping of resistance gene Gm6 against all 4 Chinese GM biotypes by RAPD and SSR methods respectively,the STS markers and SSR markers linked to gene Gm6 were used for breeding through marker assisted selection.Some new resistant germplasm with Gm6 gene were created.And 6 cultivars and 6 lines of two-line hybrid rice and 1 line of three-line hybrid rice against GM were bred and extended to the farmer.The technique system of MAS for resistant varieties against Asian rice gall midge was set up at Guangdong province of China.

用AFLP方法对从中国广东省7个地点采集的4个生物型的DAN指纹进行分析；在对用RAPD和SSR技术分别对抗中国4个稻瘿蚊生物型的基因Gm6精细定位基础上，用与Gm6紧密连锁的STS和SSR标记开展分子标记辅助育种，创造了一批抗稻瘿蚊的新种质，包括育成了6个栽培稻和6个二系杂交稻和1个三系杂交稻并在农户试种，在中国广东成功地建立了分子标记辅助选育抗稻瘿蚊品种的技术体系。

The sexual behavior of chrysanthemum gall midge, Rhopalomyia longicauda (Diptera: Cecidomyiidae) such as the release of sex pheromone and calling behavior, were studied indoors and in a field trapping experiment. The sex pheromone was collected with an organic solvent aided by a glass container of charcoal-purified air. Laboratory observations showed that most males emerged 1-2 h before females.
