The vector competence of Aedes aegypti (L.) mosquitoes, collected during the hot, rainy and cool seasons from different localities in Thailand, was tested for a correlation with a seasonal cyclic pattern of dengue incidence. Under laboratory conditions, some groups of mosquitoes exhibited differences in susceptibility to oral infection but showed no correlation to dengue cases that peak during the rainy season. Thus, the environmental conditions of each season, although they might affect a temporal change of mosquito vector competence, they might not have any direct effects on virus transmission patterns. Mosquito populations from different parts of Thailand were also likely to be homogeneous in their susceptibility to dengue virus during the study period. Other factors, such as characteristics of the virus, vector density and frequency of host-vector contact, should be considered for seasonal pattern of dengue diseases.
从泰国不同地区在炎热、雨季和凉爽季节采集的埃及伊蚊的媒介能力，被测试是否与登革热发病率的季节性循环模式相关。在实验室条件下，一些蚊群在口服感染易感性方面表现出差异，但与雨季达到高峰的登革热病例没有相关性。因此，每个季节的环境条件虽然可能影响蚊媒能力的时间变化，但可能对病毒传播模式没有任何直接影响。在研究期间，来自泰国不同地区的蚊虫种群对登革热病毒的易感性也可能是相同的。对于登革热疾病的季节性模式，应考虑其他因素，如病毒特征、媒介密度和宿主-媒介接触频率。
