Mosquito breeding in coastal South Carolina was surveyed during 1977 with emergence traps. A total of 27,362 mosquitoes was collected. The dominant species collected was Aedes taeniorhynchus which outnumbered the second major species, Ae. Sollicitans, by a factor of approximately 5 to 1. The relative abundance of these 2 species was more than 8 times higher in trap collections made from dredged material disposal sites and waterfowl management areas that were diked as opposed to unmodified saltmarsh habitats.
