目的了解西安市白纹伊蚊幼虫布雷图指数的季节消长及环境分布,分析其影响因素。方法使用布雷图指数法,对6个监测点进行监测及调查,对分布类型和容器类型数据进行统计分析。结果废旧物品回收站布雷图指数最高为13.80,各类型容器中废旧轮胎、闲置物品的阳性率分别为3.26%、2.23%。气温、降水量和布雷图指数的相关系数分别为0.863、0.909。结论不同场所布雷图指数有差异,废旧物品回收站布雷图指数最高。废旧轮胎和闲置容器伊蚊阳性率较高。7月份布雷图指数最高,气温和降水量对布雷图指数有重要影响。
Objective To understand the seasonal fluctuation and environmental distribution of the Bapti Index of Aedes albopictus in Xi’an and analyze the influencing factors. Methods The Barett index method was used to monitor and investigate 6 monitoring points, and statistical analysis was carried out on distribution type and container type data. Results The maximum value of the B & T of the waste recycling station was 13.80. The positive rates of discarded tires and unused articles in all types of containers were 3.26% and 2.23% respectively. The correlation coefficients of temperature, precipitation and Brettip index were 0.863,0.909. Conclusion There are differences in the Bret Index in different places, with the highest B & R index in the waste recycling station. The positive rate of Aedes mosquito was higher in used tires and idle containers. The Bretti Index was the highest in July, and the temperature and precipitation had a significant impact on the Bretti Chart.
