【摘要】 苹果蠹蛾Cydia pomonella(L.)(Lepidoptera:Tortricidae)是世界各国高度关注、严重危害苹果生产的外来有害生物,也是我国一类进境检验性有害生物和全国检疫性有害生物,自上世纪中叶入侵我国后,已在新疆、甘肃等地区严重发生,并逐步入侵到宁夏、内蒙古和黑龙江等省(区),目前正沿着河西走廊迅速向我国苹果优势产区逼进,形势十分严峻,因此开展苹果蠹蛾相关研究也迫在眉睫。本研究已经从我国主要疫区采集苹果蠹蛾样本,正在运用细胞核微卫星和线粒体基因标记,研究苹果蠹蛾入侵到我国疫区后种群的遗传结构、种群分化、种群间的基因流动与种群扩散规律。研究结果能够阐明我国疫区内苹果蠹蛾的遗传分化与演变特点,以及种群间的基因流动与种群扩散特点。研究结果对于预测苹果蠹蛾对我国优势苹果产区的入侵风险与入侵路线、制定符合我国疫区遗传结构和基因流动特点的综合治理策略等具有重要的意义更多还原

【Abstract】 The codling moth,Cydia pomonella(L.)(Lepidoptera:Tortricidae) is one of the most serious pest insects in apple orchards in the world as well as an A1 quarantine pest of China.In China,this pest is damaging apple production severely in Xinjiang and Gansu province and invading to Ningxia,Inner Mongolia and Heilongjiang province.The apple production of the main apple growing region of China is been threatening by C.pomonella.Information on population structure,gene flow and population distribution is important for the success of environment-friendly control technologies of this pest. Although increasingly severe damage caused by this species has been reported and the area of infestation expanded rapidly,the gene flow patterns among populations is not known in the country.In this study,we collected C.pomonella populations throughout the invested regions of China. Microsatellites and mitochondrial genes is been using to investigate the gene flow patterns among these sampled populations.The findings of this study may have important implications for invasion risk assessment,invasive routes predicting and IPM(integrated pest control) of C.pomonella populations in China.更多还原
