目的 通过准确地鉴定中山口岸入境船舶截获的蜚蠊，为今后口岸鉴定该种蜚蠊提供参考依据。方法 2017年2月24日在中山口岸截获的圭亚那进口原木中截获1只雄性蜚蠊，对其进行形态鉴定及描述，获取其DNA条形码序列并提交至GenBank。结果 经形态鉴定，该雄性蜚蠊为染色硬翅蠊，隶属于蜚蠊目姬蠊科。经科技文献查新，确认为我国未见分布种且为国内口岸首次截获。结论 DNA条形码是形态鉴定的强有力补充，DNA条形码数据库有待完善和补充，应用形态鉴定和DNA条形码相结合可准确快速地鉴定外来蜚蠊。
Objective To identify the intercepted cockroach rapidly and accurately. Methods We tried to identify the male cockroach intercepted from an entry ship at Zhongshan port on February 24, 2017 with morphology, then DNA barcodes. DNA barcodes was submitted to the GenBank and the morphological characteristics of the intercepted sample were illustrated as well. Results The male individual was identified as Ceratinoptera picta, belonging to Ectobiidae, Blattodea. Ceratinoptera picta is a non-recorded species in China and it is intercepted for the first time at Chinese ports based on Sci-Tech novelty search. Conclusion DNA barcoding is a strong supplement to morphology. At present, DNA Barcoding Data system needs to be replenished and provides references for the future use. Combining morphology and DNA barcoding techniques is suggested in identification of intercepted cockroach rapidly and accurately.
