First record of Thrips hawaiiensis (Morgan, 1913) (Thysanoptera: Thripidae) in mainland New Zealand using morphological and molecular techniques

This is the first record of an established colony of Thrips hawaiiensis (Thysanoptera: Thripidae) found on mainland New Zealand. The established population was discovered on gorse (Ulex europaeus) in Auckland, North Island. Thrips hawaiiensis is highly polyphagous and feeds and breeds in many ornamental flowers, fruit and vegetable plants including several of economic importance to New Zealand. The DNA sequences of the New Zealand specimens shared 92–99% identity with those of T. hawaiiensis in the BOLD database, indicating high intraspecific variation. The sequence analysis revealed three distinct sub-clades of T. hawaiensis, with the New Zealand specimens being in the same sub-clade as those from Australia. A comparison of COI sequences across nine congeneric species demonstrated that the COI sequence can be used to separate these species. http://zoobank.org/urn:lsid:zoobank.org:pub:CF0F6AD1-D752-4FEE-8BA4-E9CCF8D3FDB4

本研究首次记录了在新西兰本土发现的已定殖的夏威夷蓟马（Thrips hawaiiensis，缨翅目：蓟马科）种群。该定殖种群发现于北岛奥克兰地区的欧洲荆豆（Ulex europaeus）上。夏威夷蓟马为多食性昆虫，可在多种观赏花卉、果蔬植物上取食并繁殖，其中包含多种对新西兰具有经济重要性的物种。新西兰标本的DNA序列与生命条形码数据系统（BOLD）中夏威夷蓟马的对应序列相似度达92%~99%，表明其种内变异程度较高。序列分析显示夏威夷蓟马存在三个独立的亚进化枝，新西兰标本与澳大利亚标本处于同一亚进化枝中。对9个同属物种的细胞色素C氧化酶亚基I（COI）序列进行比对后发现，COI序列可用于区分这些物种。http://zoobank.org/urn:lsid:zoobank.org:pub:CF0F6AD1-D752-4FEE-8BA4-E9CCF8D3FDB4
