Controlling sites where mosquitos breed is a key strategy in breaking the cycle of infectious transmission of the dengue virus. Preventive behaviors, such as covering water containers with lids and adding temephos (commercially named Abate sand) in water containers are needed to reduce and control mosquito breeding sites. This study aimed to investigate the impact of dengue-preventive behaviors on Aedes immature production.
This cross-sectional study used in-person interviews to record occurrence of dengue-preventive behaviors in Bang Kachao, Samut Prakan Province, Thailand. Larval mosquitos in and around houses were observed and recorded, and covered 208 households.
It was found that 50% of these households had containers for drinking water and 94% used water containers. Covering water containers with effective lids showed the best success among dengue-preventive behaviors for reducing Aedes immature production. Adding temephos in water containers also was effective.
Such behaviors substantively affected development of Aedes immatures in and around households.
控制蚊虫滋生地是打破登革热病毒感染传播循环的关键策略。需要采取预防措施，如用盖子覆盖水容器和在水容器中添加涕灭威（商品名为 Abate 沙），以减少和控制蚊虫滋生地。本研究旨在调查登革热预防行为对伊蚊幼虫产生的影响。
本横断面研究使用面对面访谈记录泰国北榄府 Bang Kachao 地区登革热预防行为的发生情况。观察并记录了房屋内及周围的幼虫蚊虫，并覆盖了 208 户家庭。
发现这些家庭中有 50%有饮用水容器，94%使用水容器。用有效盖子覆盖水容器在减少伊蚊幼虫产生方面是预防登革热最有效的行为。在水容器中添加涕灭威也很有效。
这些行为对家庭内外伊蚊幼虫的发育有实质性影响。
