摘要
The codling moth, Cydia pomonella L. （Lepidoptera： Tortricidae）, is a destructive insect pest in the fruit production. The emergences of this notorious pest frequently cause the huge economic loss of apple orchards. It can also attacks pears, walnuts and other tree fruits. The codling moth is an important invasive species in China, which first appeared in Kuerle, Xijiang in 1953 and rapidly expanded in the whole area, in 1987 the codling moth spread to Dunhuang, Gansu. Recently, researchers from the Institute of Plant Protection, Chinese Academy of Agricultural Sciences, Nanjing Agricultural University and so on initiated a genome-sequencing project of the codling moth. The genome size of the codling moth is 650 Mb, as estimated by flow cytometry and survey sequencing. Since the heterozygousity is a potential obstacle in sequencing the insect genome, the research consortium carefully measured the heterozygousity of the codling moth by SNP analysis and 17-mer estimation, showing that the heterozygousity of the codling moth is around 0.3-0.6%. The whole genome shotgun strategy is adopted and a sequencing plan has been made and officially started. The availability of the codling moth genome should be of great value to uncover the molecular invasion mechanism, high adaptive ability to the stress and to develop efficient control strategies of this pest worldwide and in China.
