Dengue remains a significant public health issue in the Western Pacific Region. In the absence of a vaccine, vector control is the mainstay for dengue prevention and control. In this paper we describe vector surveillance and vector control in the Western Pacific countries and areas. Vector surveillance and control strategies used by countries and areas of the Western Pacific Region vary. Vector control strategies include chemical, biological and environmental management that mainly target larval breeding sites. The use of insecticides targeting larvae and adult mosquitoes remains the mainstay of vector control programmes. Existing vector control tools have several limitations in terms of cost, delivery and long-term sustainability. However, there are several new innovative tools in the pipeline. These include Release of Insects Carrying a Dominant Lethal system and Wolbachia, an endosymbiotic bacterium, to inhibit dengue virus in the vector. In addition, the use of biological control such as larvivorous fish in combination with community participation has potential to be scaled up. Any vector control strategy should be selected based on evidence and appropriateness for the entomological and epidemiological setting and carried out in both inter-epidemic and epidemic periods. Community participation and interagency collaboration are required for effective and sustainable dengue prevention and control. Countries and areas are now moving towards integrated vector management.
登革热仍是西太平洋区域一个重大的公共卫生问题。在没有疫苗的情况下，病媒控制是登革热预防和控制的主要手段。在本文中，我们描述了西太平洋国家和地区的病媒监测和病媒控制情况。西太平洋区域各国和地区所采用的病媒监测和控制策略各不相同。病媒控制策略包括化学、生物和环境管理，主要针对幼虫滋生地。使用针对幼虫和成年蚊子的杀虫剂仍然是病媒控制项目的主要手段。现有的病媒控制工具在成本、投放方式和长期可持续性方面存在若干局限性。然而，有几种新的创新工具正在研发中。这些工具包括释放携带显性致死系统的昆虫以及沃尔巴克氏体（一种共生细菌），以抑制病媒中的登革热病毒。此外，将食蚊鱼等生物防治方法与社区参与相结合有扩大推广的潜力。任何病媒控制策略都应根据昆虫学和流行病学背景的证据及适用性来选择，并在流行间期和流行期都加以实施。有效的可持续登革热预防和控制需要社区参与和机构间协作。各国和地区目前正朝着综合病媒管理方向发展。
