摘要

目的研究广东省雷州市乌石镇的埃及伊蚊与广东省各地白纹伊蚊的种间竞争，评估埃及伊蚊的扩散能力。方法 2017年3－8月，将捕自乌石镇的埃及伊蚊与广东省各地白纹伊蚊2龄幼虫各100条在养蚊室混合人工饲养，羽化18 d后，用电动吸蚊器吸取成蚊进行分类，计数，并收集所有蚊卵，放入水中进行下一世代混养，共进行6个世代的混合饲养，通过数量的多少比较不同蚊种的竞争能力。结果每批蚊虫首先羽化的蚊种是埃及伊蚊，白纹伊蚊的羽化要晚3 d以上。雷州市乌石镇的埃及伊蚊数量在每个世代均多于本镇的白纹伊蚊平均数量和梅州市的白纹伊蚊数量；有5个世代比茂名市的白纹伊蚊多，1个世代少；有4个世代比雷州市企水镇、韶关和深圳市白纹伊蚊数量多，2个世代少；有2个世代比湛江市的白纹伊蚊多，4个世代少；有1个世代比广州市的白纹伊蚊多，5个世代少。结论雷州市乌石镇埃及伊蚊对广东省梅州、茂名、韶关和深圳市等地的白纹伊蚊具有较强的竞争力。

Abstract

Objective To investigate the interspecific competition between Aedes aegypti from Wushi town of Leizhou and Ae. albopictus from different places in Guangdong province, China, and to evaluate the dispersal ability of Ae. aegypti. Methods From March to August 2017, 100 second-instar larvae of Ae. aegypti from Wushi town and 100 second-instar larvae of Ae. albopictus from one of selected places in Guangdong province were mixed and raised in a mosquito room. Eighteen days after emergence, all adult mosquitoes were collected with an electric mosquito vacuum for classification and counting, and all mosquito eggs were collected and put in water for next-generation rearing. A total of six generations of mixed rearing were conducted to compare the competitiveness of different species by the number. Results In each generation, Ae. aegypti was the first to emerge, and Ae. albopictus emerged more than three days later. The number of Ae. aegypti from Wushi town of Leizhou was more than the average number of Ae. albopictus in this town and the number of Ae. albopictus from Meizhou in each generation; there were five generations more than that from Maoming, one generation less; there were four generations more than that from Qishui town of Leizhou, Shaoguan and Shenzhen, two generations less; there were two generations more than that from Zhanjiang, four generations less; there was one generation more than that from Guangzhou, five generations less. Conclusion Aedes aegypti from Wushi town of Leizhou has strong competitiveness against Ae. albopictus from Meizhou, Maoming, Shaoguan, and Shenzhen of Guangdong province.
