【摘要】 1.本文报告了济南市蚊虫种类,孳生地,栖息场所,幼虫发现季节,尖音库蚊淡色变种成虫、幼虫及白纹伊蚊幼虫的密度调查结果。 2.过去在济南曾有人作过蚊类的初步观察,而此次调查较为普遍。共采获蚊类标本3属11种。其中吉浦伊蚊、拟态库蚊、二带喙库蚊、褐尾库蚊4种为济南市新发现之蚊种。其中褐尾库蚊在山东省为首次发现。 3.3属蚊虫中以尖音库蚊淡色变种为最普遍,其与居民之关系亦最为密切;次之为白纹伊蚊与中华按蚊。 4.尖音库蚊淡色变种之幼虫从5月上旬开始出现,到8月中旬达最高峯,9、10月份渐少,到11月下旬绝迹。白纹伊蚊之幼虫,8月上旬密度最高,9月中旬绝迹。各种蚊幼 之密度随雨量之增减而消长。更多还原

【Abstract】 A survey on the species of mosquito, their resting places as well as their breeding placeswas carried out during the period from March 1953 to September 1956. Altogether 11 species in 3 genera were discovered; they are: C. pipiens var. pallens, C.tritaeniorhynchus, C. virax, C. mimeticus, C. fuscanus, C. bitaniorhynchus, A. hyrcanus var.sinensis, A. pattoni; Ae. albopictus, Ae. koreicus, and Ae. chemulpoensis. Among these, C. mime-ticus, C. bitaeniorhychus, C. fuscanus and Ae. chemulpoensis are new records in Tsinan, Shan-tung. Of the 11 species, C. pipiens var. Pallens is the most common inside the human dwellings,while A. hyrcanus var. sinensis and Ae. albopictus are the next common ones. Anopheles hyrcanusvar. sinensis was found in the plains and A. pattoni in the hilly regions. The first batch oflarvae of C. pipiens var. pallens was found on May 6th. and the last are in late November.The highest peaks of seasonal distribution curve of larvae of C. pipiens var. pallens and Ae.albopictus were in the mid-August and early August respectively. The density of larvae of thevarious species is closely related to the rainfall in the yeas.更多还原
