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。Objective To observe the biological habits of the anopheles pattoni in local areas to know their role and energy m the spread of malaria. Methods By means of the combination of field investigation and laboratory methods, investigate the ter- ritory of anopheles pattoni life, history cycle, seasonal fluctuation, nocturnal bite problem, human blood ratio and other factors in the south of Suiping county. Results Data of five consecutive years showed the mosquito species exist only in the hills and mountains appear in early May and disappear in late October. The larvae can be seen throughout the year. The first ring of re- productive nutrition was （2.5 ± 0.5）days; the entire life cycle period was （12.5 ± 1.0）days; there was 17 anopheles pattoni bitten people in 60 night during 5 years. Biting rate was 0.23, suck human blood index was 0. 0465. Its population quantity, bite Index, suck human blood index and the transmitting ability were significantly lower than those of the other local anopheles pattoni; Three times＇ artificial vivax infection failed. Conclusion Anopheles pattoni is not the the transmitting media of disease in central plains.
