Drastic modifications in agrarian space, with the reductions of primary forests, along with changes in rural production systems have led to the growth of salaried employment and also caused rural workers to move to the peripheral areas of cities. There has also been an intense and continuous intervention undertaken by the Superintendência de Controle de Endemias (SUCEN) through the use of pesticides in the fight against triatomine bugs in houses and peridomestic areas of the State of S. Paulo. All these factors have contributed to the interruptions of the natural transmission of Chagas' disease in S. Paulo. The next step in the program was the integration of vertical vector control into primary health care involving community participation. The several years of SUCEN's work among the rural communities has encouraged them to notify the presence of triatominae bugs, and prompt response to each notification has led to the growth of the process of permanent participation. Data from 1985 and 1986 showed that 85.6% of the bugs captured inside houses were notified by the population, which confirms that the best way to maintain the epidemiologic surveillance of Chagas' disease by the mobilization of local communities for effective participation in vector surveillance.

Nuevos registros de triatominos domiciliarios y extradomiciliarios en Colombia / Colombian domiciliary and extradomiciliary triatomines

Se presenta informacion nueva sobre triatominos domiciliarios y extradomiciliarios en Colombia, que complementa los datos ya conocidos. De las 17 especies de triatominos registrados, el R. prolixus es el vector biologico mas importante de T. Cruzi y T Rangeli para el hombre por ser especie domiciliaria, muy susceptible a los tripanosomas, y poseer corto periodo defecatorio post-prandial. El T. Dimidiata y en menor grado T Maculata y T. venoso pueden tambien jugar un papel en la transmision intradomiciliaria. Las especies restantes son silvestres y responsables de las tripanosomiasis de animales. Se informa el primer registro de Panstrongylus Lignarius en Colombia. Las regiones Catatumbo Oriental -subregiones Pie de Monte, Macarena y Meta Cercano- y Valle del Rio Magdalena son las areas endemicas de T. Cruzi debido a la presencia de colonias domiciliarias de R. Prolixus. Se informa el hallazgo de R. Prolixus silvestre. La captura de adultos alados de esta especie en casas sin infeccion chagasica, sugiere falta de transmision domiciliaria

[Triatominae capable of transmitting Trypanosoma cruzi in Cuba]. / Triatomíneos capaces de trasmitir el Trypanosoma cruzi en Cuba.

A brief review of the species of the genus Triatoma that have been described in some epidemiology books is made. Triatoma rubrofasciata has been found at the Oriente province in our country. Triatoma flavida has been found at the Pinar del Río, Las Villas, Camagüey, and Oriente provinces. Both insects transmit the Chagas' disease.
