四川独特的地理位置、丰富的自然资源,已经成为生物入侵的重灾区,造成了巨大的经济损失.明确四川入侵生物的种类,对开展入侵生物的研究与治理意义重大.在实地调查的基础上,结合我国各类数据库、检验检疫名录以及国内外相关文献,确定四川省日前已有入侵害虫51种,其中,昆虫45种,线虫3种,螨虫、软体动物和爬行动物各1种.原产地分析结果表明,入侵到四川省的害虫种类数量由高到低的地区依次为亚洲、美洲、欧洲、非洲、大洋洲.对危害较为严重的桔小实蝇、舞毒蛾、蔗扁蛾、松材线虫、福寿螺等5种入侵害虫的危害现状进行详细叙述,并提出了应对生物入侵的若干策略,为四川省入侵害虫的深入研究、检疫部门制定预警体系与综合治理提供一定的依据.%Sichuan has become the hardest hit area of invasive organisms because of its unique geographical location and abundant natural resources,and has caused great economic losses.It is of great significance to clarify the species of invasive organisms in Sichuan and further study on invasive organisms.This paper is based on the investigation,combined with China's database,the inspection and quarantine list and the related literature at home and abroad,Sichuan province currently has 51 kinds of invasive pests,including 45 species of insects,3 species of nematodes,and 1 species of mites,mollusks,reptiles.The results of provenance analysis showed that the number of pest species invaded into Sichuan province from more to less was Asia,America,Europe,Africa,Oceania,respectively.The present status in damage of dorsalis,gypsy moth,opogona sacchari,pine wood nematode and apple snails were described for their serious economic loss,and put forward some strategies to deal with the biological invasion in Sichuan province,providing basis and reference for intensive study,establishing early-warning system and comprehensive management to invasive pests in Sichuan province.
