【摘要】 (一)作者在1950—1951年,曾收集中国81个地区的臭虫标本,作一系统的调查研究,这81个地区包括23省和内蒙古自治区。 (二)在81个地区所采集到的标本,有55个地区只有温带臭虫,44个地区只有热带臭虫,其余15个地区两种臭虫均有发生。 (三)气温是影响臭虫分布的重要因素之一。热带臭虫的分布,北至福建的建阳,广东的乐昌,湖南的衡阳,贵州的遵义,四川的成都(李、孟1951),西康的雅安,这些地区的冬季气温大都在4°—8℃。在这些北分布地区以北的地区,冬季气温较低,大多不适于它的生长,温带臭虫的抗寒力较强,在华北、东北、西北均有发生,它的分布南至福建的厦门,广东的曲江、广西的桂林、贵州的平塘(李、孟1951)、云南的蒙自,这些地区夏季气温均在30℃以下,仍可适于它的生长。 (四)地理上的经度与臭虫的分布并无关系,但纬度与臭虫的分布有关,热带臭虫的分布北至北纬30°41″(成都),它的发生地带以热带为主,在亚热带亦可生长,温带臭虫的分布南至北纬23°25′(蒙自),它的发生地带以亚热带及温带为主但传入部分的热带地区,亦可生长。 (五)地势过高可以影响热带臭虫的发生,在昆明、大理、昭通、丽江等地,拔海高度均在1922米以上,热带臭虫并无发生,但对温带臭虫并不影响。 (六)气压与地势的高低有关,昆明、大理,昭通、丽更多还原

【Abstract】 1. In order to study the distribution of the two species of bedbugs,Cimex lectularius and C. hemiptera, 81 representative localities of 23provinces and Inner Mongolia were selected for the collection ofbedbugs.2. Among the 81 localities, 55 had only C. lectularius, 11 had onlyC. hemiptera, while the remaining 15 localities had both species.3. Atmospheric temperature forms one of the most important factorslimiting the distribution of bedbugs. Consequently C. hemipteralimits itself in the North at Chian-Yang of Fukien, Lo-Chang ofKuangtung, Heng-Yang of Hunan, Tsun-I of Kweichow, Ch’eng-Tuof Szechuan and Ya-An of Sik’ang. In these localities the wintertemperature is usually at 4°- 8℃. North of this belt, because thewinter temperature is much lower, the condition is not suitable forthe existence of this species. Cimex lectularius is more resistant tocold. It is, however, less resistant to extreme heat. In localities inSouth China where the summer temperature runs over 30℃, thecondition is not suitable for the survival of this species. Its southernlimit of distribution has been found to be a line connecting Amoy,Chu-Kiang of Kuangtung, Kwei-Lin of Kuangsi, P’ing-T’ang of Kwei-chow and Meng-Tze of Yunnan.4. The relationship of latitude, altitude, atmospheric pressure andhumidity to the biology of bedbugs were briefly discussed.更多还原
