基于CLIMEX模型的扶桑绵粉蚧在中国潜在地理分布预测

The potential geographical distribution of Phenacoccus solenopsis Tinsley based on the CLIMEX in China

本研究以实际测定的发育起点温度和有效积温为基础,采用CLIMEX系统对扶桑绵粉蚧在中国的适生性地理区域作了预测。结果表明,扶桑绵粉蚧在我国的潜在分布区域广泛,除西藏、青海、黑龙江3个省区的大部地区以外,可覆盖包括长江中下游、黄河中下游、西北内陆3大主要棉区以及华南和辽河流域的零星棉区所有地区,是一种对我国各棉花产区均具有潜在危险性的害虫。

In this study, the potential geographical distribution of an invasive pest, Phenacoccus solenopsis in China was evaluated by using CLIMEX model system. Analyzed parameters of the development threshold temperature and minimum degree - clays used in CLIMEX were obtained from laboratory experimental observation. The results showed that P. solenopsis had a wide range of potential distribution in China. Except for most area of Tibet, Qing- hal and Heilongjiang provinces, this invasive pest could potentially establish all cotton producing area in China. It indicated that this invasive pest imposed a potential threat to almost all cotton producing areas in China .
