Abstract

Abstract Ecological analysis was used to evaluate over 2 yr of adult mosquito surveillance data from Citrus County, Florida. The analysis was intended to demonstrate a systematic approach to make better use of the abundance of surveillance data as a prerequisite to predict future mosquito population trends. Twenty-eight mosquito species (157,600 individuals) were collected using a modified New Jersey light trap. Analysis of species dominance index revealed that the seven most dominant species comprised 84% of the total individuals captured. Three culicine mosquitoes, Culex quinquefasciatus, Cx. nigripalpus, and Cx. erraticus, showed recurring seasonal abundance peaks in July and August, while two anopheline species, Anopheles crucians and An. atropos, showed interannual abundance variability. The population of the salt-marsh mosquito, Ochlerotatus taeniorhynchus, consistently peaked in June and July, while that of Oc. infirmatus peaked in September and July of 1999 and 2000, respectively. With 66% Oc. tae...
