Abstract:

　【Abstract】　Objective　To study dividing line and influence factor of Aedes albopictus in Shaanxi province.  Methods　Adult mosquitoes were captured by mosquito?net trap, light trap and mosq?ovitrap method.  Results　Ae.albopictus distributed widely in Baoji and Hancheng city, and mainly at the special places such as worn type deposit places and junk recycle bin in Longxian and Tongchuan city. There was no Ae.albopictus in Yijun, Huangling and Yichuan. The peak of Ae.albopictus was in August in Baoji city and in September in Hancheng city. Temperature was possible the decisive factor that affected dividing line of Ae.albopictus. Conclusion　The western boundary of Ae.albopictus was in Baoji city, the northern ones in Longxian, Tongchuan and Hancheng. Compared to light trap, mosquito?net trap and mosq?ovitrap method were best for the surveillance of Ae.albopictus, which would provide the ecological evidence for the control of mosquitoes.

摘要：

【摘要】　目的　调查白纹伊蚊在陕西省分布的西北边界变化及其影响因素。方法　成蚊调查采用帐诱法、诱蚊灯法和诱蚊诱卵器法。结果　白纹伊蚊在宝鸡、韩城市广泛分布于各类生态环境，在陇县、铜川市主要分布于废旧轮胎堆放处等特殊场所，宜君、黄陵、宜川等县未发现白纹伊蚊。该蚊活动高峰宝鸡市在8月，韩城市在9月。温度可能是决定白纹伊蚊分布北界稳定的限制气候因子。结论　白纹伊蚊在陕西省分布的西部边界到宝鸡市，北部边界到陇县、铜川市（王益区）、韩城市连线地带。白纹伊蚊监测采用帐诱法和诱蚊诱卵器法可获得可靠结果，诱蚊灯法不适宜作为白纹伊蚊监测，本调查也为蚊虫防制提供了生态学依据。
