This study is a contribution to the inventory of medicinal plants and other methods used in controlling external parasitic diseases of backyard poultry in the localities of Djougou and Ouaké (department of Donga, Benin ResumoEste estudo é uma contribuição ao inventário de plantas curativas e outros métodos endógenos usados no combate aos ectoparasitos de pássaros de currais nas aldeias de Djougou e Ouaké (departamento do Donga, em Benin). A pesquisa foi conduzida entre dezembro de 2010 e março de 2011, durante visitas e entrevistas com 210 criadores de aves. Os resultados indicam que 13 espécies de plantas curativas são utilizadas no combate aos ectoparasitos. Annona senegalensis, Tectona grandis, Securidaca longepedunculata, Indigofera hirsuta, Lophira lanceolata, Hyptis spicigera, Steganotaenia araliacea, Oxytenanthera abyssinica, Nicotiana tabacum, Jatropha curcas, Ficus exasperata, Azadirachta indica e Parkia biglobosa, são usadas para tratar uma doença parasitária externa na área de estudo. Annona senegalensis foi a planta mais frequentemente usada (18%, p < 0.05) como medicação contra os parasitas externos das aves. Outras receitas tradicionais como o óleo de palma e a cinza tem sido comunicadas.

The PSP have contributed to a significant reduction in morbidity in the commune of Aguégués.

The Affon River is one of the important rivers of the Ouémé River whose benthic diversity remained unknown. The present study aims to make the relationship between macroinvertebrates and physico-chemical parameters to access water quality of the Affon River. The measurement of physico-chemical parameters (temperature, pH, conductivity, transparency, depth and TDS, dissolved oxygen, ammonium, nitrite and phosphate) and the sampling of macroinvertebrates using a Surber net were carried out during floods in eight stations. A principal component analysis (PCA) and canonical correspondence analysis (CCA) were used. The indices of Shannon, Piélou, Simpson, Hilsenhoff, EPT and EPT/Chironomidae were used to assess the level of water pollution. The study identified 9755 macroinvertebrates divided into 4 classes, 14 orders and 49 families. Pollution-sensitive families (14 families) that are organic pollution indicators, as well as pollution-tolerant families (Chironomidae, Limnaeidae, Bithynidae, Physidae) were captured. Chironomidae were the most predominant and abundant family (FO = 100%). The predominance of Chironomidae coupled with the rarity of the Ephemeroptera, Trichoptera and Plecoptera would reflect the poor quality of the Affon River waters. The principal components analysis yielded groups of associations: The first group of stations Taneka 2 and 3 characterized by high values of ammonium and phosphate; and low values of conductivity and TDS; the second group of Tanéka 1 and Kolokondé 1 stations with low values of pH, transparency, ammonium and phosphates; and the third group of stations Kolokondé 2, Kpébouko1, Kpébouko 2 and Affon marked by high values of conductivity, TDS, transparency, depth and temperature. The canonical correspondence analysis revealed a strong positive correlation between Nemou

The present study was conducted in the commune of Kérou in North Benin to measure the bioavailability of agricultural pesticides heavily used in the production of cotton on snails. The test was conducted in peasant environment in two villages of the commune. In each site, there are three cages containing 6 snails each. The snails are exposed to soil and plants without special protection and are therefore exposed to environmental conditions. Firstly it's to evaluate the presence or absence of agricultural pesticides in the viscera of snails after exposure. Secondly it consists to compare the different doses found in the viscera of snails in the different sites. And finally it's to evaluate the effect of the toxicity of the pesticides on the reproduction of snails. The tests consisted of placing steel cages in the two experimental sites. In each site, there are three cages containing 6 snails each. Snails are exposed to soil and plants without special protection and are therefore exposed to environmental conditions. The observations were made in order to establish a study of transfer kinetics. After the analysis of the data, it appears generally that the accumulation of mineral elements highlighted is not proportional to the mineralogical composition of the soil in which the snail is exposed. Total nitrogen and nitrate were significantly accumulated in the flesh of site 2 snails compared to site 1 snails. These different measures show the bioavailability of soil minerals for living organisms. Accumulations are not necessarily accompanied by toxic effects in terms of survival for snails after 28 days of exposure. However, the absence of immediate toxic effect on snails does not imply a lack of effect in food chains due to the trophic availability of contaminants. The use of snails as bio-indicator of soil quality has therefore proved relevant in the context of soils polluted by minerals. How to cite this paper: Gouissi, F.M. and Adimi, A.E.

To appreciate the access to water, hygiene and sanitation in the commune of Abomey-Calavi, the inventory was carried out and the associated factors in terms of water, hygiene and sanitation have been studied. From May 2016 to January 2017, a cross-sectional and analytical study was used to administer a structured questionnaire to 630 individuals. SPSS and Epi Info were used to analyze the associated factors. The focus groups were used to

This study focuses on the biodiversity of macroinvertebrates of the Affon River. To reach this goal, eight stations were sampled and physical parameters such as temperature, pH, conductivity, transparency, depth, total dissolved solids (TDS) and dissolved oxygen were measured. Chemical parameters such as ammonium nitrite and phosphate were measured in the laboratory. We identified 9755 macroinvertebrates belonging to 4 classes, 14 orders, and 49 families. Chironomidae were the most abundant family whereas other sensitive insect's orders such as Ephemeroptera, Trichoptera, and Plecoptera were rarely found, suggesting a poor water quality of the Affon River. The principal components analysis yielded three groups of stations: the first group (Tenéka 2 and 3) characterized by high values of ammonium and phosphate and low values of conductivity and TDS; the second group (Tanéka 1 and Kolokondé 1) with low values of pH, transparency, ammonium and phosphate; and the third group of stations (Kolokondé 2, Kpébouko1, Kpébouko 2, and Affon) marked by high values of conductivity, TDS, transparency, depth and temperature. This study is a crucial step for any management and monitoring of the Affon River.
