Abstract:

,In order to foresee the diffusion areas of Holcocerus hippophaecolus in Xinjiang and its potential damage to the sea buckhorn of those areas, the research potential climate suitable distribution of Holcocerus hippophaecolus in Xinjiang was predicted by CLIMEX and GARP software, from parts of sea buckhorn’s distribution, the host economical importance, possibility of spreading and diffusion, management difficulties of H. hippophaecolus to analyze the risk in Xinjiang. The result showed that most part of Xinjiang had the risk about H. hippophaecolus. Combined the raise area and status of distribution, it indicated that Turpan Basin, Yili region, Aletai region, Kizilsu Kirgiz region, Kasgar region and Hotan region are adequate for H. hippophaecolus to exist, and most of this place were high suitable regions. Combined the judging standard of quantitative analysis of pest risk assessment, R value of H. hippophaecolus was 2.24. It was a high devastating forest pest in Xinjiang Uygur Autonomous Region. And it was dangerous for the ecosystem, soil and water conservation and forest economy of Xinjiang. So it was important to take effective measures to control the damage and diffusion of H. hippophaecolus, it suggested that to let H. hippophaecolus in the supplement list of forestry quarantine pest for Xinjiang.
