发布时间：2018-09-17 14:25
【摘要】：目的观察帕氏按蚊在当地的生物习性,了解其传播疟疾的作用及能量。方法采用现场调查及实验室相结合的方法,在豫南遂平县境内对帕氏按蚊的生活史周期、季节消长、夜间活动叮人情况、吸人血比率等因素进行调查研究。结果连续5年的研究资料显示:该蚊种仅在丘陵山区存在,5月上旬出现,10月下旬消失,幼虫全年均可见到。第一个生殖营养环为(2.5±0.5)d,全部生活史周期(12.5±1.0)d;夜间叮人5年60夜17只,叮人率仅为0.23,吸人血指数为0.0465,其种群数量、叮人指数、吸人血指数及媒介能量均明显低于当地的中华按蚊;间日疟原虫人工感染3次均未成功。结论帕氏按蚊不是中原传播疟疾的媒介。
[Abstract]:Objective to observe the local biological habits of Anopheles parvisiae and to understand its function and energy in malaria transmission. Methods the factors of life cycle, seasonal fluctuation, nocturnal bite and blood absorption rate of Anopheles parviens were investigated in Suiping County, South Henan Province by field investigation and laboratory method. Results after 5 years of continuous research data showed that the mosquito species only existed in hilly and mountainous areas. It appeared in early May and disappeared in late October. The larvae could be seen all year round. The first cycle of reproductive nutrition was (2.5 卤0.5) days, the whole life cycle was (12.5 卤1.0) days, and the nocturnal biting rate was 0.23 and the blood intake index was 0.0465. The population number, biting index, sucking blood index and vector energy of Anopheles sinensis were significantly lower than those of the local Anopheles sinensis (Anopheles sinensis). Three times of artificial infection of Plasmodium vivax were unsuccessful. Conclusion Anopheles parvies is not the vector of malaria transmission in Central Plain.
