ABSTRACT
Mark-release-recapture experiments were conducted in 2001 and 2002 to determine whether Ochlerotatus taeniorhynchus, black salt marsh mosquitoes, were dispersing from uninhabited islands in the Key Deer National Wildlife Refuge to inhabited islands within Monroe County, Florida. An estimated 1,658,000 mosquitoes were marked during 2001, and an estimated 300,000 mosquitoes were marked during 2002. Recapture rates were 0.0061% and 0.0117%, respectively. Oc. taeniorhynchus disperse from uninhabited islands to other uninhabited islands and also to inhabited islands, namely, Big Pine Key and No Name Key.

More than 30,000 mosquitoes in 22 species or species groups were collected from the Florida Keys, Monroe County, FL, USA, in dry ice-baited light and gravid traps. Dry ice-baited traps collected more mosquitoes than did gravid traps. West Nile virus was detected in pools of Anopheles atropos Dyar & Knab, Deinocerites cancer Theobald, and Ochlerotatus taeniorhynchus (Wiedemann).
