从南非鲜橙上截获重要害虫坚果异胫小卷蛾

Interception of macadamia nut borer Thaumatotibia batrachopa from South African orange

坚果异胫小卷蛾是南非果树上重要经济害虫。珠海检验检疫局曾在南非鲜橙中截获过该虫。本文对坚果异胫小卷蛾的分布、寄主及成虫形态特征进行了描述,并分析了该虫的DNA条形码检测方法。通过GenBank数据库比对分析,邻接法构建的系统发育树及BOLD数据库查询比对,可最终确定所截获害虫为坚果异胫小卷蛾。

The macadamia nut borer Thaumatotibia batrachopa is a major pest of economic importance on South Africa fruit trees. It was intercepted in South African fresh orange by Zhuhai Entry-Exit Inspection and Quarantine Bureau. This paper described its distribution,host plants,morphological characteristics,and used DNA barcoding technique to indentify this pest. Sequence was blasted with released data in GenBank and BOLD database,and phylogenetic tree basing on the neighbor-joining algorithm was contructed,the results comfirmed that the intercepted pest was macadamia nut borer Thaumatotibia batrachopa.
