海南岛自1959年大规模开展抗疟以来,以微小按蚊为主要传疟媒介的地区,经过室内滞留喷洒已受到了有效的控制,从而阻断了疟疾的传播,疟疾发病率显著下降。但是,以大劣按蚊为主要传疟媒介的山林区,由于该蚊种的野栖习性,多年来虽经多种防制措施,仅能降低密度和寿命的作用,这些地区疟疾仍在不断传播,大劣按蚊成为当前海南岛最重要的传疟媒介。为了进一步研究 Since the large-scale anti-malaria campaign in Hainan Island in 1959, Hainan Island has been effectively controlled by indoor retention spraying in areas where the mosquito is the dominant transmission vector for malaria, thus blocking the spread of malaria and significantly reducing the incidence of malaria. However, because of the habitat of the mosquito species, mosquitoes, which are predominantly malaria vectors, can only reduce their density and longevity over the years, malaria is still on the rise in many areas Dissemination, Anopheles dirus has become the most important vector of transmission of malaria in Hainan Island.
