报道中国大陆1新纪录种,美洲棘脊蓟马Echinothrips americanus Morgan,1913(缨翅目,蓟马科,蓟马亚科),这也是棘蓟马属Echinothrips Moulton,1911在中国大陆的首次纪录.目前该种仅在我国北京海淀区的辣椒上发现.棘蓟马属以头、前胸背板和后胸背板具网状刻纹与针蓟马亚科Panchaetothripinae特征十分相近,但以发达的中胸内叉骨刺与之相区别.美洲棘蓟马系检疫性害虫,本文列出了它的世界分布和寄主植物种类.实证标本保存在浙江大学昆虫科学研究所.

FIRST RECORD OF ECHINOTHRIPS AMERICANUS MORGAN(THYSANOPTERA,THRIPIDAE)IN MAINLAND CHINA,WITH NOTES ON DISTRIBUTION AND HOST PLANTS

Echinothrips americanus Morgan of the subfamily Thripinae(Thysanoptera,Thripidae) collected on pepper from Beijing is reported in this paper,which represents the first record of both the genus and the species from mainland China.Although the head,pronotum,and metanotum are reticulately sculptured,the genus differs from members of Panchaetothripinae in having the mesofurcal spinula well-developed.It is one of the quarantine pest species that expanded its range of distribution in a relatively short tune.The distribution and list of its host plants are given.The specimens were deposited at the Institute of Insect Sciences,Zhejiang University,Hangzhou,China(ZJUH).
