摘　　要：目的　探讨三带喙库蚊春季首现日的一种温度评判方法。方法　 1982～ 1992年和2 0 0 1～ 2 0 0 2年在上海市奉贤地区每年 3月 1日开始 ,每天在猪舍内挂诱蚊灯全夜 (18时至次日 6时为一灯夜 )灯诱捕蚊 ,麻醉后对三带喙库蚊进行计数 ,取每灯夜平均蚊虫数为其密度。将三带喙库蚊春季首现日与首现日前 7天、首现日当天和后 1天计 9天同期日平均气温作比较分析。结果　采用首现日当天和前 1天或首现日当天、前 2天和后 1天任意连续 3天的日平均气温值及其日平均气温累积值判断三带喙库蚊春季首现日其差异在 1～ 2天内 (91.7% )。结论　三带喙库蚊春季首次出现时 ,伴随着一次来源于南方强暖气团影响当地气温的过程 ,其日平均气温下限值为 11.0℃。据此 。ObjectiveTo find out an appraisal meth od of temperature on the first appearance date of Culex tritaeniorhynchus in s pring. MethodsWhole night collection of mosquitoes mosquitoes ( from 18∶00 hours to 06∶00 hours of the follow ing day)with light traps had been carried out in pigsties every night since 1 Ma rch in 1982-1992 and 2001-2002 in Fengxian area Shanghai. The adult mosquitoes caught were anaesthetized,then identified and counted. The density of mosquitoe s was calculated by the average number of mosquitos per one trap and one night. Comparative analysis of the mean daily air temperature at 7 days before,the fir st appearance date and 1 day after, the first appearance date of Culex trita eniorhynchus. ResultsData of the first appearance data of Culex trit aeniorhynchus were judged to mean daily air temperature and cumulative tempera ture on the day of the first appearance of Culex tritaeniorhynchus and the d ay before appearance, or 3 days on the day of the first appearance of Culex tr itaeniorhynchus and the two days before appearance and the day since appearan ce with a diffence less than 1-2 day ( 91.7 %). ConclusionThe first appearance of Culex tritaeniorhync hus in spring accompanied with a course of influence by the severe warm air a dvection from south of China, and lowest mean daily air temperature of the firs t appearance was 11℃. Thus the first appearance data of Culex tritaeniorhynch us could be deduced and rehabilitated from observed values of mean daily air t emperature or its forecasting values.
