Abstract:

Objective To investigate the distribution of mosquitoes in Chenlu scenic spot of Tongchuan, Shaanxi province, China to provide guidance for mosquito control. Methods Lamp-baited trap and human-baited net trap were used for assessing the density of adult mosquitoes. The positive rate of water containers in the external environment of residential area was determined, and the container index, house index, and Breteau index were determined to assess the density of mosquito larvae. Results According to the data collected using lamp-baited trap, the mean density of adult mosquitoes was 0.0874 mosquito/lamp·hour; the density of adult mosquitoes was highest in July (0.2018 mosquito/lamp·hour) and in farm for tourism (0.1429 mosquito/lamp·hour), followed by residential area (0.1078 mosquito/lamp·hour). According to the data collected using human-baited net trap, the mean density of adult mosquitoes was 7.4419 mosquitoes/net·hour; the density of adult mosquitoes was highest in August (30.6000 mosquitoes/net·hour). In the residential area, the mean container index was 14.48%, and the container index was highest in August (21.87%); the house index and Breteau index of residential area were 35.88% and 76.08%, respectively. Conclusion There are plenty of breeding places for Aedes, especially various water containers, in the environment of Chenlu scenic spot, and the density of Aedes albopictus is the highest. Measures should be taken to remove accumulated water and control the density of Ae. albopictus.
