Resumo: Stem borers (Insecta: Lepidoptera) in Africa emerge as a major biotic constraints to cereal production. The distribution of species depends on the region and the losses tend to be higher in altitude. For the monitoring of species of stem borers in Angola were used sex pheromone traps for Busseola fusca, Chilo partellus and Sesamia calamistis that were installed in Cavaco, Alto Kapaka, Cela, Chianga and Humpata. To study the management of populations of stem borers using the push-pull system were held in Huambo tests, using as attractive plant Pennisetum purpureum and as repellent plant Desmodium uncinatum. It was found that the three species monitored were present at all sites sampled B. fusca was the dominant species in Chianga, Cela and Alto Kapaka and S. calamistis in Cela and Cavaco. In capturing the pheromone B. fusca ‘Pherobank’ was significantly more effective than pheromone ‘Insect Science’. The incidence of attacks of borers in maize ranged between 86.2% in the control and 14.4% in the treatment maize x P. purpureum x D. uncinatum. For the four years of trials the average production increase in treatment that used attractive and repulsive plants was 340.6%, compared to maize alone
