基于BIOCLIM模型的扶桑绵粉蚧在中国的适生性分析

Potential Distribution of Phenacoccus solenopsis in China by the BIOCLIM Model

采用BIOCLIM生态位模型对扶桑绵粉蚧(Phenacoccus solenopsis Tinsley)在中国潜在适生地理区域和各区域的适生可能性进行预测。扶桑绵粉蚧在中国适生区域非常广泛,高度适生区包括黄河以南的广大华南、华中、华北地区,中低度适生区包括河北、辽宁、山西、内蒙古、宁夏、甘肃、新疆、西藏等省区的部分区域。这些适生区域覆盖中国3大棉区,其中长江中下游棉区和黄河中下游棉区为扶桑绵粉蚧的高度适生区,西北棉区为其低度适生区。

In this study, the potential geographical distribution of an invasive pest, P. solenopsis in China was evaluated by using the BIOCLIM model system, the distribution possibility of each place was also evaluated. The results showed that P. solenopsis had a wide range of potential distribution in China. The high potential distribution area was the vast area in south of the Yellow River, including South China, Central China and North China. The medium and low potential distribution area was part of some provinces including Hebei, Liaoning, Shanxi, Inner Mongolia, Ningxia, Gansu, Xinjiang and Tibet. These potential distribution areas established three major cotton producing areas in China. The middle and lower reaches of Yangtze River cotton producing area and the middle and lower reaches of the Yellow River cotton producing area were the high po- tential distribution area, the northwest cotton producing area was the low potential distribution area.
