The 17th Annual Latin American symposium presented by the American Mosquito Control Association (AMCA) was held as part of the 73rd Annual Meeting in Orlando, FL, in April 2007. The principal objective, as for the previous 16 symposia, was to promote participation in the AMCA by vector control specialists, public health workers, and academicians from Latin America. This publication includes summaries of 57 presentations that were given orally in Spanish or presented as posters by participants from 6 countries in Latin America, Puerto Rico, and the USA. Topics addressed in the symposium included results from chemical and biological control programs and studies; studies of insecticide resistance; and population genetics, molecular, ecological, and behavioral studies of vectors of dengue (Aedes aegypti and Ae. albopictus), Venezuelan equine encephalitis (Culex spp.), West Nile viruses (Cx. nigripalpus and Cx. quinquefasciatus), malaria (Anopheles spp.), leishmaniasis (Lutzomyia), and onchocerciasis (Simulium).
