20世纪50年代福建省流行性乙型脑炎严重流行期间,在灭蚊后蚊密度极低的情况下,仍见乙脑病例发生。调查人员注意到台湾蠛蠓(台蠓)季节分布与乙脑流行季节相符,在自然界捕获的台蠓中分离得乙脑病毒,并经生物学实验证明能致小鼠发生乙脑,认为其属乙脑新媒介,同时实验观察了其从卵、幼虫、蛹到羽化成虫的全过程,认识了幼虫形态,并发现幼虫在水中不能生活的特点,认定系陆生。并据此在遮阴的青苔土与草丛腐殖土中查到了孳生场所,揭开了台蠓生活史与孽生地的秘密;并对防控台蠓的方法做了部分试验,随后其他专家亦在调研上取得了许多进展,凡此均为防控台蠓及乙脑提供了新的科学办法。
During the severe epidemic of Japanese encephalitis in Fujian Province in the 1950s, cases of Japanese encephalitis were still observed in the case of very low mosquito density after mosquito control. Investigators noted that the season distribution of Taiwan catfish (Taiwanese) is in line with the epidemic season of Japanese encephalitis. Japanese encephalitis virus was isolated from Taiwan catfish captured in nature and was proved to be capable of causing Japanese encephalitis in mice by biological experiments At the same time, we observed the whole process from eggs, larvae and pupae to eclosion adults, recognized the morphology of larvae and found that larvae can not live in water. According to this, the place of breeding was found in shady moss soil and grass humus so as to reveal the secrets of Taiwanese life history and evil land. Some experiments were conducted on the method of preventing Taiwanese taiwan. Other experts Much progress has been made in the investigation and research, and all these have provided a new scientific approach to preventing and controlling Taihe and JE.
