The second Spanish language symposium presented by the American Mosquito Control Association (AMCA) was held as part of the 58th Annual Meeting in Corpus Christi, TX in March 1992. The principal objective, as it was for the 1991 symposium, was to increase and stimulate greater participation in the AMCA by vector control specialists and public health workers from Latin America. This publication includes summaries of 25 individual presentations that were given in Spanish. The symposium included the following topics: biology and chemical control of Aedes aegypti and anopheline vectors of malaria; field and laboratory studies of biological control agents for Aedes aegypti; community participation in the prevention of dengue; and other various aspects of the biology of other medically important arthropods (e.g., Simulium ochraceum, Lutzomyia and Culicoides).
