目的探讨不同城市化程度居民区白纹伊蚊幼虫的孳生地特点,为控制白纹伊蚊密度提供依据。方法于2004年3月至2005年11月选择城市化程度高的佛山市城区和城市化程度低的揭阳市城中村为调查点,在选定的试验区按随机的原则,每5户选择1户调查其室内外白纹伊蚊幼虫的孳生情况,数据采用SPSS11.0软件进行统计。结果共调查7470户,积水5635处,阳性502处,阳性率6.72%,显示揭阳市城市化程度低的城中村居民区白纹伊蚊的孳生地类型主要为闲置容器(碗、瓶、缸、罐)和贮水容器(池、缸、盆),其阳性构成比分别为64.98%和18.77%,闲置容器的阳性构成比在每年的9月达到最大值为83.67%;佛山市居民区白纹伊蚊的孳生地类型主要为盆景、水生植物和闲置容器,其阳性构成比分别为45.52%和33.79%,闲置容器的阳性构成比每年的7-9月所占比例最大达100%,盆景、水生植物的阳性构成比在2004年、2005年5月所占比例较大,最大值达到75.00%,2005年5月后其所占比例为0。结论不同类型的居民区其白纹伊蚊的孳生地构成有一定的差别,并随着季节的变化而变化,城市化程度高的居民区白纹伊蚊的孳生地主要是盆景、水生植物和闲置容器,城市化低的城中村主要是闲置容器及贮水容器。
Objective To investigate the breeding characteristics of Aedes albopictus larvae in residential areas with different degrees of urbanization and provide evidence for controlling the density of Aedes albopictus. Methods From March 2004 to November 2005, we selected the urban areas of Foshan with a high degree of urbanization and the urbanization of Jiezhong with a low degree of urbanization as the survey sites. In the selected experimental areas, we randomly selected 1 Household investigation of indoor and outdoor Aedes albopictus larvae breeding situation, the data using SPSS11.0 software statistics. Results A total of 7470 households were surveyed with 5635 hydronepsis and 502 positives with a positive rate of 6.72%. The results showed that the main types of breeding areas for Aedes albopictus in Chengzhongcun residential area in Jieyang City were idle containers (bowls, bottles, cylinders) , Pots) and water storage containers (tanks, tubs and pots), the positive constituent ratios were 64.98% and 18.77%, respectively. The positive constituent ratio of idle containers reached a maximum of 83.67% in September each year. Aedes albopictus breeding places are mainly bonsai, aquatic plants and idle containers, the positive constituent ratios were 45.52% and 33.79%, respectively, the positive composition of idle containers from July to September each year accounted for up to 100% of the proportion of bonsai , The positive ratio of aquatic plants in 2004, 2005, a larger proportion, the maximum reached 75.00% after May 2005 its share of 0. Conclusion There are some differences in the breeding grounds of Aedes albopictus between different types of residential areas and with the change of seasons. The breeding ground of Aedes albopictus in residential areas with high degree of urbanization is mainly bonsai, aquatic plants and Idle containers, low urbanization in the village is mainly idle containers and storage containers.
