中文摘要：
【目的】了解旱稻种植区农户和稻田成蚊发生规律及其相关性。【方法】 7—10月在3个成对的农户和稻田调查点，二氧化碳诱蚊灯法采集成蚊。Kruskal-Wallis和Kendall’s W分别分析组内（农户、稻田）和组间（农户和稻田间）的成蚊发生差异。线性回归法分析农户和稻田成蚊发生关系。【结果】 南京江宁旱稻生长期农户和稻田捕获成蚊4种，三带喙库蚊Culex tritaeniorhynchus为绝对优势种（优势度>98%）；7—10月间成蚊发生具显著的波峰和波谷消长态势。3个调查点农户间、稻田间、农户和稻田间的成蚊密度均无显著差异，7—10月间农户和稻田成蚊发生高线性相关（相关系数R2=0.64，P＜0.01，n=21）。 【结论】 旱作水稻田依然是蚊虫（成蚊和幼蚊）主要的野外生存环境；
农村稻区的蚊虫防治、乙脑等蚊媒传染病的预防控制应充分考虑当地稻田情况，以大稻区为整体开展相关防治工作。
英文摘要：
[Objectives] To determine the relationships between adult mosquito population dynamics of peasant households and dry rice paddies. [Methods] We used CO2 -light mosquito traps to collect adult mosquitoes at 3 paired households and paddy sampling spots semi-monthly from July to October in suburban Nanjing. We applied Kruskal-Wallis and Kendall’s W methods to test the intra-group (households or paddies) and inter-group (households and paddies) difference in adult mosquito densities, and regression analysis to determine the relationship between adult mosquito temporal dynamics of households and paddies. [Results] The local mosquito community was comprised of only 4 species, and dominated by Culex tritaeniorhynchus which comprised more than 98% of all specimens captured. Mosquito temporal dynamics were characterized by peaks and troughs in both households and paddies. We found no significant differences in either intra or inter-group mosquito densities. In addition, semi-monthly mosquito densities in households and paddies had a significant linear relationship (R2=0.64). [Conclusion] Dry rice paddies are still the major habitat of mosquitoes in both suburban and rural areas. Rural mosquito control, as well as Japanese encephalitis prevention and control, should take rice paddies into consideration.
