摘　　要：目的：探讨郑州中华按蚊种群生殖，存活的规律。方法：实验得出郑州中华按蚊的年龄特征存活率和产 雌率，建立生命表，分析该蚊实验种群的动态变化。结果：郑州中华按蚊成蚊前期的各期发育历期：卵为 ２．１０２６ ｄ，幼 虫期为 １０．８７５０ ｄ，蛹为 ２．０１１３ ｄ，成蚊前期为 １４．９８８ ９ ｄ。成蚊前期各期存活率：卵为 ８３．２５１３％，幼虫为 ９２．１８９ ７％， 蛹为９５．５７３ ５％。郑州中华按蚊的性别比为１．０５８：１，平均寿命雌雄分别为１３．１５５４ ｄ和６．５７３ ５ ｄ，预期寿命雌雄分别 为 １３．８２８ ８ ｄ和 ８．３２９ ２ ｄ，最长寿命雌雄分别为 ３２．０００ ０ ｄ和 １４．０００ ０ ｄ。郑州中华按蚊的产卵特性：羽化到第 １次产 卵的时间为 ２．５７０ ０ ｄ，最大产卵年龄为３０．０００ ０ ｄ，每雌平均产卵数为 １９．０８４ ３个／ｄ，每雌平均产卵总数为 ５１５．２７６ ０ 个。根据以上数据，绘制了该蚊各年龄特征存活率和产雌率的曲线图，编制了雌、雄中华按蚊生命表。结论：郑州中 华按蚊实验种群生命表的确立，为该蚊种群数量的预测预报和确立预防管理策略提供了科学依据。Aim: To discuss the law of Anopheles sinensis population's reproduction, survival in Zhengzhou.Methods: The method of life table was used to analyse population trends. Results: The growth periods of each stage of pre-adult period of Anophe- les sinensis were as follows: 2. 102 6 d for egg stop, 10.875 0 d for larval stage, 2.011 3 d for pupal stage, 14.988 9 d for pre-adult stage. The survival rates of each stage of pre-adult period of Anopheles sinensis 189 were as follows: 83.251 3% for egg, 92. 189 7% for larvae, 95.573 5% for pupa. The sex ratio was l.058: 1. The mean life-span of female and male 13.155 4 d and 6.573 5 d, respectively. The expected life-span of female and male were 13.828 8 d and 8.3op 2 d respectively. The longest life-span of fe- male and male were 32.000 0 d and 14.000 0 d respectively. Time from eclosion to the first oviposition was 2.570 0 d. The largest age of oviposition was 30.000 0 d. The number of oviposition of each female was 19.084 3/d, and the total number of oviposition of each female was 515.276 0. According to these data, diagrams of survival rate and female-oviposition rate and life tables of male and female mosquito population were drawn up. Conclusion: Life table for experimental population of Anopheles sinensis in Zhengzhou provide the scientific basis for population's number forecast and drafting the tactics for prevention.
