The first ever integration bloc in Africa was formed back in the colonial era in 1910, when a number of British colonies were integrated. Modern integration processes in the African countries in the south of the Sahara began much later, from the early 1960s, when most of the former colonies gained independence, and it was during this period that the construction of a number of economic blocks began. The article reveals integration processes in West Africa and sub-Saharan African countries features. Integration as such is viewed as a complex procedure, with the success way which depends on many factors. On the experience of the Republic of Mali, the authors demonstrated how an irrational socio-economic policy can lead to deformation of integration processes, which inevitably threatens with deep financial and socio-political crises.

Abstract The South American fruit fly, Anastrepha fraterculus (Wiedemann, 1830) (Diptera: Tephritidae), is an important pest in the subtropical region of Brazil. This insect has tritrophic relation between wild fruits and parasitoids and is associated with apple (Malus domestica Borkh.) orchards adjacent to the Atlantic Forest in Paraná. We thus investigated the degree of infestation of the fruit fly and natural parasitism in wild and cultivated fruits surrounding apple orchards. For this purpose, we collected fruits of Acca sellowiana (Berg.) Burret, Campomanesia xanthocarpa (Mart), Eugenia uniflora L., Eugenia pyriformis Cambessèdes, Psidium cattleianum Sabine, Psidium guajava (L.), Annona neosericea Rainer and Eriobotrya japonica (Thumb) in apple orchards adjacent to the Atlantic Forest located in Campo do Tenente, Lapa and Porto Amazonas counties. In total, we collected 18,289 fruits during four growing years. The occurrence of A. fraterculus depends on the susceptible period of apple fruits. A. sellowiana and P. cattleianum were considered primary fruit fly multipliers and P. guajava was secondary, all occurring after the apple harvest (IS period). The group of parasitoids with A. fraterculus was Aganaspis pelleranoi (Brèthes, 1924) (Hymenoptera: Figitidae), Opius bellus (Gahan, 1930), Doryctobracon areolatus (Szépligeti, 1911) and Doryctobracon brasiliensis (Szépligeti, 1911) (Hymenoptera: Braconidae) all of which are first records in the Atlantic Forest in Paraná. First record of O. bellus occurring in the State of Paraná, as well as, first record of the tritrophic association between host plant A. neosericea, parasitoids D. areolatus and O. bellus and fruit fly A. fraterculus. The host P. cattleianum stood out among the Myrtaceae species in regard to the high diversity of parasitoid species (81% of parasitoids). The total number of Figitidae species (76.5%) was higher than that of Braconidae species. The influence of climatic events in southern Brazil on wild fruit production should be further studied to understand the association of A. fraterculus with the tritrophic relationship.

The article presents the results of expeditionary surveys to collect local populations of species-related wheat (Aegilops L.) from various agroecological zones of Samarkand and Kitab districts of Samarkand and Kashkadarya regions of Uzbekistan. 140 samples of seeds of local populations of five species of the genus Aegilops L. were collected and a collection of local populations of species-relatives of wheat was formed, which is a unique genetic resource for enriching the wheat gene pool.
