白纹伊蚊（Skuse）是登革热病毒的一种蚊媒，在日本流行，广泛分布于本州岛，其北部界限在北纬38度至40度之间。利用地理信息系统（GIS）对日本北部地区的分布影响因素进行了研究。1998-2000年期间，在本州岛北部东北地区的26个城市和农村地区进行了幼虫监测，从人工和自然生境收集幼虫。利用地理信息系统（GIS）进行气候学分析，发现伊蚊的分布主要受以下条件的影响。白纹伊蚊：年平均气温高于11度，最冷月份1月平均气温高于-2度。在蚊子确定的地区，每年气温连续高于11度的时间超过186天。从11℃计算的积温，可能接近伊蚊的发育零度。白纹伊蚊，温度超过1350度。本文还讨论了东北地区九、十月的月平均气温与短日照开始、诱导卵滞育的关系。我们还展示了Ae的电流分布之间的关系。白纹伊蚊和美国的年平均气温。从这些结果可以预测Ae。白纹伊蚊将在美国东北部的一些城市出现。
Aedes albopictus (Skuse), a mosquito vector of the dengue fever virus, is prevalent in Japan, distributed widely in Honshu Island with its northern limits between latitude 38degrees to 40degreesdegrees north. The factors affecting distribution of the species in the northern part of Japan were studied using the geographical information system (GIS). During 1998-2000, larval surveillance was carried out in 26 urban and rural areas in the Tohoku district, in the northern part of Honshu Island, by collecting larvae from artificial and natural habitats. Climatological analysis, using the GIS, showed that the following conditions accounted for the current distribution of Ae. albopictus: an annual mean temperature higher than 11degreesC and a mean temperature of the coldest month, January, higher than -2degreesC. A period with temperature above 11degreesC in the confirmed area of the mosquito successively continues for more than 186 d per year. The accumulated temperature calculated from a temperature of 11degreesC, which may be close to the developmental zero of Ae. albopictus, was over 1,350 degree-days. The relationship between the beginning of short-daylength, inducing egg diapause, and the monthly mean temperature during September and October necessary for successful larval development in the Tohoku district is also discussed. We also show the relationship between the current distribution of Ae. albopictus and the annual mean temperature in the United States. From these results it is predicted that Ae. albpictus will be established in some cities in northeast United States.
