消灭传染媒介我国地区辽阔,各地的主要传瘧蚊种不尽相同。在华南地区,主要传染媒介大约以微小按蚊与中华按蚊为主,其他如日月潭按蚊、白踝按蚊等也可以传瘧长江和黄河流域主要传染媒介为中华按蚊。所以在同传染媒介作斗争时,应先了解当地主要传染媒介的生态习性,而后根据生态习性采取有效措施。一般说来,在营区应以灭蚊为主,野营或外出执勤时,以防蚊为主。兹就一些可用的方法,介绍如下。1.消灭越冬按蚊:时间应在春天进行,因为春天到了,温度开始上升,在6-10℃时,越冬成蚊开始飞出觅食,此时牛房中蚊数最多,没有牛时,其他牲畜栏舍蚊数也多。在防治瘧疾时,可在牲畜体表喷上杀虫剂,让蚊虫停落时,接触杀虫剂而死亡。方法是:先测量牲畜体表面积(约为3.5-4.0平方公尺),每平方公尺应用剂量为50%的可湿性二二三2-3克,或
Eradication of vector China’s vast territory, around the main transmission mosquito species vary. In South China, the main vectors are mainly Anopheles minimus and Anopheles sinensis. Others such as Anopheles anopheles, Anopheles stephensi, etc. can also transmit the malaria vectors of An. Sinensis to the Yangtze River and the Yellow River. Therefore, in fighting the vector, we should first understand the ecological habits of the local main vectors, and then take effective measures according to ecological habits. In general, anti-mosquito should be the mainstay of the camp area when camping or going out on duty. Here are some available methods, described below. 1. Elimination of wintering Anopheles: time should be carried out in the spring, because the spring is coming, the temperature began to rise, at 6-10 ℃, the overwintering adult mosquitoes began to fly out foraging, this time the largest number of cattle in the mosquito, no cattle, Other livestock stalls mosquito count more. In the fight against malaria, insecticides can be sprayed on the surface of livestock so that when the mosquitoes stop falling, they will come into contact with insecticides and die. The method is to first measure the body surface area of the animals (about 3.5-4.0 m ^ 2), apply 50% of the wettable amount per m ^ 2 to 2-3-3 g, or
