本文根据1982～1989年对三带喙库蚊早春出现情况的连续观察结果,结合气象资料,分析了上海海滨三带喙库蚊首次出现与地面风和高空风的关系,并与中华按蚊进行比较。结果发现三带喙库蚊首次出现日与地面S-ESE风向和高空SSW-W风向的吻合率显著高于中华按蚊,说明三带喙库蚊早春首次出现与地面S-ESE风向和高空SSW-W风向有关,提示该蚊早春虫源随南支天气系统由外地迁入的可能性。
Based on the continuous observations on the occurrence of Culex tritaeniorhynchus in early spring from 1982 to 1989 and the combination of meteorological data, the relationship between the first appearance of Culex tritropiformis in Shanghai seashore and surface wind and wind at high altitude was analyzed and compared with that of Anopheles sinensis Compare The results showed that the coincidence rate between the first appearance day of Culex tritaeniorhynchus and the S-ESE wind direction and the SSW-W wind direction was significantly higher than that of Anopheles sinensis, indicating that the phenomenon of Culex tritaeniorhynchus first appeared in early spring with ground S-ESE wind direction and altitude SSW -W wind direction, suggesting that the mosquito early spring insect source with the southern branch of the weather system from the field into the possibility.
