【摘要】 【目的】了解白纹伊蚊幼虫布雷图指数与居民住宅楼层的关系,为登革热媒介蚊虫防制提供科学依据。【方法】在不同居民住宅楼层,采用布雷图指数法监测白纹伊蚊幼虫。【结果】共调查居民744户,发现有白纹伊蚊孳生的阳性容器33个,布雷图指数为4.44。阳性容器中以水盆景及水生植物阳性率最高,占78.79%。不同高度楼层居民户调查布雷图指数差异无统计学意义(χ~2=1.33,P>0.05),7层及以上高层居民户与低层居民户同样存在白纹伊蚊阳性孳生情况。【结论】在流行季节应重视高楼层白纹伊蚊幼虫的调查和控制,方可有效做到登革热媒介防控。更多还原

【Abstract】 [Objective] To ascertain the relationship between Breteau index and storey in Aedes albopictus L.(A.albopictus) surveillance,providing guidance for dengue fever control. [Methods] Density of A.albopictus larva was surveyed by Breteau index(BI) on different residential floors. [Results] A total of 744 households were surveyed.Thirty-three positive containers of A.albopictus were found and Breitmap index was 4.44.Bonsai and aquatic plants had the highest positive rate,accounting for 78.79%.There was no statistical difference in Breteau index between different levels of floor households(χ~2 =1.33,P>0.05).The positive breeding was also found in high-rise residential households above 6 floors. [Conclusion] It is necessary to strengthen investigation and control on the density of A.albopictus.High-floor surveys should not be ignored either during the epidemic season so as to effectively prevent and control dengue fever.更多还原
