目的调查四川省登革热媒介白纹伊蚊的分布情况,为登革热的防治提供依据。方法在全省选择10个监测点,采用定时、定点、定人调查法,对白纹伊蚊孳生环境中的幼虫指数和成蚊密度进行监测。结果10个监测点幼虫的容器指数为27.50%,成蚊总密度为8.08只/人工小时。以废旧轮胎容器指数最高,为60.28%;特殊场所和养殖耕种区密度较高,分别为18.17和10.08只/人工小时;夏季密度也较高,峰值达到9.79只/人工小时;白纹伊蚊的密度有地区差异,但无地理位置差异;各个监测点幼虫与成蚊密度高低有一定的相关性。结论白纹伊蚊在四川省分布广泛,一旦有登革热病例输入,就可能造成疫情扩散。因此,应加强监测。
Objective To investigate the distribution of dengue vector Aedes albopictus in Sichuan Province and provide evidence for the prevention and treatment of dengue fever. Methods Ten monitoring points were selected in the whole province. The larval index and adult mosquito density in Aedes albopictus breeding environment were monitored by timed, fixed-point and person-survey methods. Results The container index of larvae in the 10 monitoring spots was 27.50%, and the total adult mosquito density was 8.08 / man hours. The highest index of waste container was 60.28%. The density of special place and culture area was 18.17 and 10.08 / man-hour respectively. The density in summer was also higher, with the peak reaching 9.79 / man-hour. The Aedes albopictus There are regional differences in density, but no geographical differences; each monitoring point larvae and adult mosquitoes have a certain degree of density. Conclusion Aedes albopictus is widely distributed in Sichuan Province. Once a dengue fever case is imported, it may cause the epidemic to spread. Therefore, monitoring should be strengthened.
