Objective To provide scientific guidance for the prevention and control of dengue fever and Zika disease outbreak by field control of Aedes albopictus which was carried out by vegetation barrier treatment and the methods of rapid and sustainable effective control of Ae. albopictus were explored. Methods During August-October, high efficient cypermethrin microcapsule suspension (barrier treatment residual spraying) and cypermethrin emulsion were sprayed on the vegetation of Ae. albopictus. The density of Ae. albopictus was monitored by human landing counts and was observed before and after application and analyzed by Excel 2007 software. Results The density reduction rate was 96.0%, 99.0%, 85.0%, 84.0%, 47.3%, and 3.0% respectively on the first day, and in the first through the fifth weeks, respectively, in the trial of cypermethrin microcapsule suspension. The densities of the Ae. albopictus were reduced by 83.0%, 77.0%, and -25.0% respectively on the first day, and in the first and the second week, respectively, in the trail of cypermethrin emulsion. Conclusion The application of vegetation barrier treatment can persist more than 3 weeks. It has the advantages of long lasting effect, resistance to rain water wash, time and labor savings, reduction of environmental pollution,and so on. This technique has a good application prospective to mitigate outbreak of Zika virus and other infectious diseases.
