Subsoil drain sumps are a key container for Aedes aegypti in Cairns, Australia
Journal of the American Mosquito Control Association 20 (4), 365-369
Abstract: The contribution of subterranean drain sumps to pupal and adult populations of Aedes aegypti is reported for the 1st time in Cairns, Australia. Pupal surveys were used to quantify the relative contribution of drain sumps to the total population of Ae. aegypti by concurrent survey of sump and water-bearing containers in yards of inner-city premises. A total of 854 mosquito pupae were collected, predominantly Ae. aegypti and Culex quinquefasciatus (26.3 and 69.8%, respectively). Drain sumps provided a relatively uncommon (n = 4) but productive source for pupal Ae. aegypti, producing 14.7% of the combined yard and drain sump population. Drain sumps in inner-city Cairns most commonly occurred in parking lots (52.6%). Subsequently, a sticky emergent adult trap (SEAT) was developed to provide a pragmatic method to assess production of Ae. aegypti by drain sumps. A total of 866 adult mosquitoes were trapped from 162 drain sumps over a 48-h exposure period, comprising Ae. aegypti and Cx. quinquefasciatus (21 and 79%, respectively). Advantages of the SEAT are an ability to rapidly count, identify, and sex mosquitoes and to provide specimens for molecular analysis where necessary. The treatment of water-bearing drain sumps is a critical element of control campaigns against Ae. aegypti.
