(1)对肯尼亚的8个疟疾媒介种群进行了为期3年的抽样。对每个人口进行了长达一个月的抽样。测量相对密度、分娩率和妊娠率。每个种群由冈比亚按蚊、阿拉伯按蚊、大按蚊或福氏按蚊组成。(2)通过相关分析确定了数据的一致性和产卵周期的平均持续时间。八个数据集中有四个被认为适合分析。每个产卵周期的平均存活率由零截距的普通最小二乘线性回归确定。(3)产卵周期为2~4d。(4)冈比亚按产卵周期存活率与中华按蚊相当。阿拉比星的存活率较低。(5)干季冈比亚按蚊的预期感染寿命最长，产卵周期最长。讨论了这些结果对疟疾流行病学的影响。
(1) Eight populations of malaria vectors in Kenya were sampled over 3 years. Each population was sampled for up to one month. Relative density, parous rate and pre-gravid rate were measured. Each population consisted of a single species of Anopheles gambiae, A. arabiensis, A. merus or A. funestus. (2) The coherence of the data and the mean duration of the oviposition cycle were determined by cross-correlation analysis. Four of the eight data sets were considered suitable for analysis. The mean survival rate per oviposition cycle was determined by ordinary least squares linear regression with zero intercept. (3) The oviposition cycle ranged from 2 to 4 days. (4) The survival rates per oviposition cycle were similar for A. gambiae and A. merus. The survival rate of A. arabiensis was lower. (5) The expected infective life was longest for A. gambiae in the dry season, when the oviposition cycle was longest. The implications of these results for malaria epidemiology are discussed.
