沙巴采用室内杀虫剂喷洒已有20多年历史,主要媒介巴拉巴按蚊对二二三尚未产生抗性。由于媒介的野栖习性,二二三室内喷洒不能阻断疾病传播。为此,想采用驱避性较少的杀螟松和马拉硫磷作小规模现场试验,期能降低媒介存活率,并利用其熏蒸作用弥补室内喷洒未能完全覆盖的缺点。
Sabah has been spraying insecticides indoor for more than 20 years and the main vector Anopheles parahabae has not developed any resistance to Erzine. Due to the wild habit of the media, spraying by two or three indoors can not block the spread of the disease. For this reason, small-scale field trials of fenitroth and malathion, which are less repellent, are expected to reduce the medium survival rate and utilize the fumigation effect to make up for the shortcomings of indoor spray coverage.
