Abstract:

Objective Application of insecticidal barrier spray on vegetation for dengue mosquito vector control to explore rapid and long-term effective control means for dengue mosquito vector control in the urban communities. Methods From June to September of 2015, the phoenix garden of Shaoguan city in Guangdong province was selected as the test site, comparing the effectiveness of barrier spray on vegetation technology to kill the dengue vector mosquito with the ultra low volume spraying. Results The insecticidal barrier spray on vegetation showed quick kill effect, and continuous control effect on Aedes albopictus, reducing mosquito lure egg apparatus index (MOI) lure under 5 for 2 to 4 weeks, the duration of the MOI under 10 for 3 to 6 weeks, the duration of the effective control of mosquito density for 6 to 7 weeks. Pesticide resistance was not detected. Conclusion Insecticidal barrier spray on vegetation can effectively control dengue mosquito vector density more than one month. Compared with ultra-low volume spraying, insecticidal barrier spray on vegetation reduced the cost by 37.50%, saved on-site manpower, pesticides and time, had a positive impact on dengue fever outbreak control in urban communities.

摘要：

目的 应用绿篱技术喷药进行登革热蚊媒防制现场试验，探索对社区进行登革热蚊媒快速和长期有效控制的手段和方法。方法 于2015年6－9月，选择广东省韶关市碧桂园凤凰城为试验现场，以超低容量喷药法作对照，比较绿篱技术喷药快速和持续杀灭登革热媒介伊蚊成蚊的效果。结果 绿篱技术喷药对登革热媒介白纹伊蚊成蚊具有快速杀灭效果，可持续控制环境中白纹伊蚊密度，诱蚊诱卵指数（MOI）≤5的持续时间为2~4周，MOI≤10的持续时间为3~6周，有效控制蚊媒密度的持续时间为6~7周，且未见伊蚊对相应药物产生抗性。结论 绿篱技术喷药可有效控制登革热蚊媒密度达1个月以上，与超低容量喷药法比较，其喷药面积更少，费用下降了37.50%，节省现场处理的人力、药物及时间成本，对登革热疫情暴发社区的蚊媒应急控制有积极的指导意义。
