| 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2001～2002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,可根据日平均气温实况值或温度预报值重建和预报三带喙库蚊春季首现日 |

| Objective Tofind ouTan appraisal method of temperature on the firsTappearance date of Culextritaeniorhynchus in spring.Methods Whole nighTcollection of mosquitoes mosquitoes ( from 18∶ 00 hours to 06∶ 00 hours of the following day)with lighTtraps had been carried ouTin pigsties every nighTsince 1 March in 1982-1992 and 2001-2002 in Fengxian area Shanghai. The adulTmosquitoes caughTwere anaesthetized, then identified and counted.The density of mosquitoes was calculated by the average number of mosquitosper one trap and one night. Comparative analysis of the mean daily air temperature aT7 days before, the firsTappearance date and 1 day after, the firsTappearance date of Culextritaeniorhynchus.Results Data of the firsTappearance data of Culextritaeniorhynchus were judged to mean daily air temperature and cumulative temperature on the day of the firsTappearance of Culextritaeniorhynchus and the day before appearance, or 3 days on the day of the firsTappearance of Culextritaeniorhynchus and the two daysbefore appearance and the day since appearance with a diffence less than 1-2 day ( 91. 7%).Conclusion The firsTappearance of Culextritaeniorhynchus in spring accompanied with a course of influence by the severe warm air advection from south of China, andlowesTmean daily air temperature of the firsTappearance was 11℃.Thus the firsTappearance data of Culextritaeniorhynchus couldbe deduced and rehabilitated from observed values of mean daily air temperature or its forecasting values. |
