Статья посвящена исследованию и разработке основных положений зонирования территорий насе- ленных пунктов Республики Бенин. Разработаны схемы зонирования территорий, определяющие вид использования территорий и устанавливающие ограничения, функциональное назначение и интенсив- ность использования каждой территориальной зоны. Рассмотрены нормативные правовые акты орга- нов местного самоуправления, регулирующие использование и изменение объектов недвижимости.

AbstractThe use of synthetic insecticides is responsible for many cases of resistance in insects. Therefore, the use of natural molecules of ecological interest with insecticidal properties turns out to be an alternative approach to the use of synthetic insecticides. This study aims at investigating the larvicidal, adulticidal activity and the composition of the essential oil of Aeollanthus pubescens Benth on the major malaria vector Anopheles gambiae.The leaves of Aeollanthus pubescens were collected in the South of the Republic of Benin. Three reference strains of Anopheles gambiae s.s. such as Kisumu, Kiskdr and Acerkis were used. The chemical composition of the essential oil was analysed by gas chromatography coupled to mass spectrometry. Larvae were exposed to the essential oil extract for 24 h. Adult mosquitoes were exposed to the fragment nets coated with the essential oil for 3 min. Larval mortality and adult survivorship were monitored.Fourteen components were identified representing 98.31% of the total of oil. The major components were carvacrol (51.06 %), thymyle acetate (14.01 %) and γ-terpinene (10.60 %). The essential oil has remarkable larvicidal properties with LC50 of 29.26, 22.65, and 28.37 ppm respectively on Kisumu, Acerkis and Kiskdr strains. With the fragment net treated at 165 µg/cm2, the KDT50 of both Acerkis (1.71 s, p < 0.001) and Kiskdr (2.67 s, p < 0.001) individuals were significantly lower than that of Kisumu (3.77 s). The lifespan of the three mosquito strains decreased respectively to one day for Kisumu (p < 0.001), two days for Acerkis (p < 0.001) and three days for Kiskdr (p < 0.001) compared to their control.Our findings show that the Aeollanthus pubescens essential oil is an efficient larvicide and adulticide against malaria vector Anopheles gambiae. This bioinsecticidal activity is a promising discovery for the control of the resistant malaria-transmitting vectors.

Ethno-ichthyological knowledge can improve fisheries management. This study covers interactions between ecological, morphological, and sociocultural aspects pertaining to the fish of the Tovè River, which is located in the largest fishing area in the Republic of Benin (Ouémé Valley), West Africa. In particular, data were collected on fishing methods and techniques, fishing equipment, and ichthyofauna by noting vernacular names followed by identification traits, taste and dietary value, medicinal use, and related knowledge of different species. Through data related to names given locally to fish, this paper highlights the manner in which physical or behavioral traits are coded in terminology. Most of these species have a high market value, either because they are considered to be delicacies and/or for their medicinal uses. The results suggest that ethno-ichthyological information can successfully be applied to improve fish conservation and fisheries management.

Due to the growth of the population, the need of the Republic of Benin to increase food production is growing significantly. Maize is the main cultivated crop in the country, being also the main item of nutrition. The scientific rationale for expanding the area of maize cultivation is an important economic task. GIS database was created, which includes all the necessary information on soil, relief, and climate conditions in the country for assessment the resource potential of lands for maize cultivation. Geoinformation modeling of soil and land suitability for maize cultivation was performed. The most suitable lands were identified. Possibility to expand areas for maize cultivation in the country was assessed. It was found that the largest resources (in parts of the land fund) for the expansion of maize cultivation are in the following communities of Benin: Tory-Bossito (96%), Toviklin (92.41%), Materi (90.31%), Kobli (89.25%), Wayogbe (87.99), Parakou (86.57%), Jaco-Tomey (85.66%), Avrankou (85.46%), Allada (84.13%), Bohicon (82.24%), Sakete (81.85%), Za Kpota (78.08%), Akpo Misserete (77.96%), Bopa (77.15%), Kpomasse (75.82%) and Ifania (75.03%). The findings led us to conclude that, theoretically, the gross maize production in Benin could be increased fivefold (from 1,514,913 tons to 5,513,947 tons) only by expanding the cultivation area.
