Technical Abstract: Adult mosquito control consists of barrier treatments and areal spraying often using pyrethroids, however not all host seeking insects contacting insecticides are killed. Sublethal exposure to neurotoxic compounds can negatively affect sensory organs reducing their efficiency for locating hosts. Female Aedes aegypti, Anopheles albimanus and Culex quinquefasciatus were exposed to LD25 levels of pyrethroid treatments and changes in flight orientation towards host odors subsequently evaluated. Significant behavioral changes are discussed in the context of adult mosquito control and disease transmission. Sand fly behavior was evaluated in a novel bioassay chamber and videotaped for analysis. Standard chemical treatments and novel compounds were used to treat of sleeves and Velcro patches which were then evaluated for spatial repellency of sand flies.
