Abstract:

Objective To investigate the breeding situation of mosquito larvae in the urban area of Shijiazhuang, China and to provide scientific evidence for mosquito control. Methods Direct observation was used to investigate the breeding of mosquitoes in small collected waters and container waters, and visual observation combined with scoop sampling were used to investigate the breeding of mosquitoes in large and medium-sized water bodies. Water containing mosquito larvae or mosquito larvae in water were collected and taken back to the laboratory to be classified. Results The mean positive rate was 10.94% in the large and medium-sized water bodies, such as square fountains, park landscape waters (artificial lake), and Minxin River, while 221 positive sites were found in 1120 small collected waters and container waters, with a mean positive rate of 19.73% (6.35%-38.46%). The dominant species were Aedes albopictus and Culex pipiens pallens, accounting for 42.74% and 35.55%, respectively. Conclusion Mosquito control strategy should be varied with the different chacateristics of various breeding places.

摘要：

目的 调查石家庄市区蚊幼虫孳生情况,为蚊虫防制提供科学依据。方法 于2011年7－8月对小型积水和容器积水采用直接观察法,大中型水体采用目测法结合捞勺法调查孳生情况;同时采集阳性积水或水体中的蚊幼虫带回实验室鉴定。结果 大中型水体广场喷泉池、公园景观水域(人工湖)、民心河(环城人工河),平均阳性率为10.94%;各类小型积水和容器积水1120处,蚊幼虫孳生阳性221处,阳性率在6.35%～38.46%之间,平均阳性率为19.73%。蚊幼虫孳生优势种群为白纹伊蚊和淡色库蚊,其中白纹伊蚊占42.74%,淡色库蚊占35.55%。结论 石家庄市不同水体蚊虫孳生各具特点,为蚊虫防制和治理策略制定提供了依据。
