摘要
青岛是我国重要的沿海开放城市,同时由于其特殊的地形地貌和气候条件,生物入侵形势十分严峻。目前,对青岛地区的外来农业病虫害尚未有系统调查。本研究于2013—2015年,通过查阅资料与田间调查的方法全面分析了青岛地区外来农业病虫害的种类、原产地、传入方式、为害的生态系统及其地理分布。结果表明:青岛地区外来农业病虫害共计31种,其中动物18种,微生物13种;约有56%的病虫害来源于美洲;全部病虫害通过无意识引进或自然扩散的方式入侵;约有71%的病虫害可为害农作物生态系统。调查结果对青岛地区外来农业病虫害的预防与控制提供了依据。
Qingdao is an important coastal open city in China. Additionally,owing to its special geographic character and climatic conditions,Qingdao has been invaded by many alien species. But the alien agricultural disease and insect pests in Qingdao region haven＇t been systematically investigated until now. From2013 to 2015,the species,origin,introduction pathway,invaded ecosystem and geographic distribution of alien agricultural disease and insect pests in Qingdao were analyzed by data collection and field survey. The results showed that there were 31 species of alien agricultural disease and insect pests in Qingdao,in which,18 species were animals,13 species were microbes. The 56% of the species originated from Americas. All of the 31 alien species were introduced unintentionally or naturally. The 71% of the species could damage the crop ecosystem. The results provided a basis for the prevention and control of alien agricultural disease and insect pests in Qingdao region.
