Detection of stored products pests by pheromone traps In seven warehouses in Luanda/Angola

The detection of arthropods species was conducted in seven warehouses containing several stored food products, namely, rice, maize flour, wheat flour, beans, pasta and sugar, and in a milling factory that processed rice, dried cassava and maize, located in the Luanda region, in Angola. During storage the main effect of the activity of arthropods species on food products is related to the damage they cause and the reduction of product quantity and quality that can lead to the rejection of contaminated lots. The arthropods species recorded in the survey are mentioned. A total of 27 arthropods species including insects and arachnids were identified. The insects species Sitophilus zeamais Motschulsky, Tribolium castaneum (Herbst) and Ephestia cautella (Walker) were common to the seven warehouses and in the milling factory, while Ahasverus advena (Waltl) and Oryzaephilus surinamensis (L.) were found in the seven examined warehouses.
