Description

In the present work a summary on the phytossanitary features of stored products, mainly rice, maize, maize flour and cassava flour, in some stores and processing factory situated near Luanda, Angola is presented. A questionnaire was carried out in July/ August 2002 in order to get information on the store capacity, stored foodstuffs and storage period. An entomological survey in the observed storage facilities was conducted to detect inset infestations, by visual search, sampling and using traps with and without pheromone. Twelve insect species of the orders Coleoptera, Lepidoptera and Psocoptera were identified. The insect species found in these storage places may cause deterioration to stored products and their presence is considered a serious contamination risk.
