The genetic structure of five Periplaneta americana (L.) populations from three cities (Cali, Popayán and Buenaventura) located in southwestern Colombia was estimated using the AFLP molecular marker technique. A set of 174 loci were analyzed, 120 of which were polymorphic. Genetic diversity was estimated at different geographic levels for the total population and between cities. Genetic diversity averaged 0.32. The largest gene flow was detected between two population from Cali (F ST=0.088; Nm=2.6) and the lowest from the third population in this city (Univalle) and Popayán and Buenaventura (F ST=0...

In order to qualitatively evaluate sexual behaviors or practices and the incidence of sexual and reproductive health programs in adolescent and postadolescent users educated in Cali, Colombia, two quota samples were carried out, one in schools in poor neighborhoods of the city and one at Valle University (UNIVALLE). In addition, a limited number of twelve open interviews was made among two different student population groups, the schools and the university. The study addresses the sexual behaviors of adolescents and postadolescents, contraceptive methods and prevention of STDs and HIV/AIDS, and the uses of sexual and reproductive health programs by both populations, controlling for social class (socioeconomic stratum), gender, and race...
