【摘要】 目的:探讨自然界内郑州中华按蚊种群数量变动规律。方法:在自然界内用自创的实验筒、实验网和接 近自然状况的大实验笼等工具,定点定量调查研究。结果:求出成蚊前期发育历期:7月份为 14.17 d,8月份为 13.32 d;存活率:7月份为77.53%,8月份为 85.18%;生殖营养周期:7月份为 2.48 d,8月份为 2.49 d;产卵规律:该 蚊多数在夜间产卵,产卵高峰出现在黄昏后和黎明前;平均产卵量:7月份为167粒,8月份为121粒;平均成蚊寿 命:7月份为3.93d,8月份为6.23d。结论:郑州中华按蚊在当地6月下旬和8月下旬各出现一次密度高峰,自然种 群数量大,传疟潜势高。

【Abstract】 Aim: To probe the pattern of quantitative alteration of natural Anopheles sinensis population in Zhengzhou.Meth- ods: Investigating at fixed place and quantitatively by using experimental barrels, experimental nets and experimental cages in nature.Results:The growth period of pre-adult stage was 14. 17 d for July and 13.32 d for August, the survival rate was 77.53% for July and 85. 18% for August, the gonotrophic cycle was 2.48 d for July and 2.49 d for August, the pattern of oviposition was that the most female mosquitoes oviposited at night and the peak of oviposition appeared at dawn and dusk, the mean number of oviposition was 167 for July and 121 for August, the mean life span of adult mosquito was 3.93 d for July and 6.23 d for August. Conclusion: The density peak of Anopheles sinensis population in Zhengzhou appear at the last ten days of July and August, respectively. The number of natural population was great, and the potential capacity of malaria trasmission is high.
