Technical Abstract: The traditional approach to vector control, where large geographic areas are treated with chemical insecticides, has several problems associated with it. These include development of insecticide resistance by the target species, negative impact on non-target species, high cost of insecticides, and potential environmental contamination. These problems have led to the development and evaluation of non-pesticidal (i.e. alternative) control technology. One alternative is the use of attractant-baited targets and traps. Several investigations into the potential use of attractant-baited targets and traps have recently been initiated in Florida against container breeding, fresh and brackish water breeding Aedes mosquitoes. The major species that have been targeted are Aedes albopictus, Ae. canadensis, Ae. infirmatus, and Ae. taeniorhynchus. Various combinations of attractant (e.g. 1-octen-3-ol, carbon dioxide and several patent-pending human volatile candidate attractants) were tested under field conditions with several trap types. When targets were used instead of traps, they were impregnated with lambdacyhalothrin (0.2g AI/meter squared). These targets remained effective, i.e., bioassays of field collected adult female Aedes taeniorhynchus, resulted in grater than 90 percent mortality, 30 minute post-exposure, for three weeks. Data will be presented that show the importance of species-specific attractant blends, trap type, and trap spacing in obtaining meaningful population reduction. The future prospects of removal trapping for control of nuisance and vector mosquito species will also be discussed.
