锥蝽，也被称为接吻虫，在世界各地均有发现，尤其在拉丁美洲，是传播美洲锥虫病（也称为恰加斯病）的著名自然媒介。在中国，过去曾记录有两种锥蝽（红带锥蝽和中华锥蝽）的存在。由于人口增长以及恰加斯病全球传播的风险不断增加，锥蝽成为潜在的公共卫生危害，2016年我们开始在中国南方监测锥蝽的活动。
中国疾病预防控制中心寄生虫病预防控制所收集了锥蝽标本，并在解剖显微镜下根据其形态特征进行鉴定。除形态分析外，还提取了标本的基因组DNA，并对线粒体16S rRNA、细胞色素b（CytB）基因和核糖体28S rRNA基因进行PCR扩增，以便从基因层面分析和确认物种。
在中国广东省佛山市顺德区农村的一处住宅中采集到一只雌性成虫和一只雄性成虫（北纬22°42′44.63″，东经113°08′45.34″）。形态和基因分析结果表明，这些锥蝽是红带锥蝽。
这是首次在中国南方广东省佛山市确认红带锥蝽的出现。由于已发现该锥蝽可自然感染克氏锥虫和康氏锥虫，且有证据表明其具有居家栖息能力，因此需要进一步研究以更清楚地了解该锥蝽物种的生态。

Triatomines, also known as kissing bugs, which are found throughout the world and especially in Latin America, are well known natural vectors that transmit American trypanosomiasis, also called Chagas disease. In China, the presence of two species of Triatoma (Triatoma rubrofasciata and T. sinica) was recorded in the past. Due to the growing population and the increasing risk of the global spread of Chagas disease, triatomines became a potential public health nuisance, and in 2016, we started monitoring triatomine activities in southern China. Triatomine specimens were collected by the National Institute of Parasitic Diseases, Chinese Center for Disease Control and Prevention, and identified by their morphological characteristics under a dissecting microscope. In addition to morphological analysis, the genomic DNA of the specimens was extracted, and the mitochondrial 16S rRNA, the cytochrome b (CytB) gene and the nuclear ribosomal 28S rRNA gene were PCR-amplified to analyze and confirm the species genetically. One female adult insect and one male adult insect were collected in a dwelling in the rural area of Shunde County, Foshan City, Guangdong Province, China (22°42′44.63″N, 113°08′45.34″E). The results from the morphological and genetic analyses indicated that these triatomines were T. rubrofasciata. This is the first time that the occurrence of T. rubrofasciata has been confirmed in Foshan City, Guangdong Province in southern China. Further studies are needed to reach a clearer understanding of the ecology of this species of triatomine, since it has been found to be naturally infected by Trypanosoma cruzi and T. conorhini and there is evidence of its domiciliation capabilities.
