中文摘要:

大洋臀纹粉蚧Planococcus minor Maskell和南洋臀纹粉蚧P.lilacinus Cockerell是我国有重要检疫意义的有害生物。这两种粉蚧从东盟进口水果口岸检疫中频繁截获，且已在广东、海南、云南等地发现大洋臀纹粉蚧入侵，这对我国热带、亚热带的水果和观赏植物等已构成严重威胁。本研究以大洋臀纹粉蚧和南洋臀纹粉蚧在国内外的分布数据为基础，利用Maxent生态位模型和ArcGIS对两种粉蚧在中国的潜在适生区进行预测。预测结果表明，大洋臀纹粉蚧和南洋臀纹粉蚧的适生区主要分布在长江流域以南地区，其适生区面积分别占全国面积的22.14%、18.17%，其中高度适生区域集中分布在广西、广东、云南、福建、四川、台湾、海南等地区，与我国热带水果的主要种植区域具有高度的一致性。大洋臀纹粉蚧已成功入侵，一旦南洋臀纹粉蚧传入便可迅速扩散蔓延，并对我国热带水果生产造成严重危害。因此，各口岸应加强对东盟进口水果的检验检疫，预防其新的进入和扩散。

英文摘要:

The mealybug speciesPlanococcus minor Maskell and P.lilacinus Cockerell are import quarantine pests in China. They are frequently intercepted at ports from imported fruits of ASEAN P.minor had invaded Guangdong Province, Hainan Province and Yunnan Province, and posed a serious threat to tropical and subtropical fruits and ornamental plants in China. The potential geographic distribution for P.minor and P.lilacinus were analyzed by using ecological niche model (Maxent) and ArcGIS with the occurrence records of two pests all over the world. The forecasted results indicated that south of the Yangtze River area was the potential region of P.minor and P.lilacinus, which was accounting for 22.14 percent and 18.17 percent of national region respectively. The highly suitable distribution of two pests located at Guangxi Municipality, Guangdong Province, Yunnan Province, Fujian Province, Sichuan Province, Taiwan Province and Hainan Province, where were the main planting area of tropical fruits in China P.minor had successfully invaded Guangdong Province, Hainan Province and Yunnan Province in China P.lilacinus could spread rapidly if it passed from port, and would cause serious damage to tropical fruits production. Therefore, it is imperative to enhance inspection and quarantine at ports from imported fruits of ASEAN to prevent the new invasion and spread of P.minor and P.lilacinus.
