Domestic triatomines (Reduviidae) and insect trypanosome infections in El Salvador, C.A

The results indicate that each of several factors-local variations in housing construction, insecticide afifilications, geografihic elevation, and the vector sfiecies involved-can have a critical effect on transmission of the disease agent.
