Diospyros mespiliformis Hochst. est une espèce d’arbre à usage multiple des forêts tropicales sèches qui est encore exploitée à l’état sauvage et dont les pratiques sylviculturales ne sont pas documentées. La présente étude avait pour but d’appréhender les perceptions paysannes sur l’importance socio-économique, le niveau de vulnérabilité et la pratique de la culture de cette espèce dans la zone soudanienne du Tchad. L’approche méthodologique a consisté en des enquêtes réalisées auprès de 350 personnes réparties dans 10 villages, ainsi que des observations de terrain. Les résultats ont montré que D. mespiliformis est bien connu des populations locales (100 % des enquêtés) qui en font usage dans six catégories d’usage, avec un large consensus au niveau des utilisations médicinales (Cs = 0,96), alimentaires (Cs = 0,33), dans les constructions (Cs = 0,26) et comme bois d’énergie (Cs = 0,24). Par contre le consensus est resté faible pour l’utilisation dans l’artisanat (Cs = - 0,76) et comme bois d’œuvre (Cs = - 0,83). Selon 80,2 % des répondants, les revenus tirés de l’exploitation de cette ressource contribuent significativement à l’amélioration du bien-être des ménages. En dehors de la cueillette et du ramassage des fruits, toutes les autres méthodes de récolte citées par les répondants (écorçage, prélèvement des racines, effeuillage et abatage) sont destructives, mais seulement 17,7 % des répondants en sont conscients. Une tendance régressive de la dynamique du peuplement de l’espèce est perçue par la majorité (52 %) des répondants. Selon 83,5 % des enquêtés, les habitudes en matière de culture de cette espèce sont rares voire inexistantes, à cause des difficultés de germination des graines, de la rareté des graines et des conditions climatiques défavorables à la réussite du drageonnage. Les répondants dans la quasi-totalité (99 %) se sont déclarés prêts à adopter la pratique de la culture de la plante si les contraintes de régénération sont levées. Les résultats de cette étude indiquent clairement que D. mespiliformis serait une espèce propice à la domestication participative pour l’intensification du système agroforestier dans la zone soudanienne du Tchad. Diospyros mespiliformis Hochst. is a multipurpose tree species from tropical dry forests that is still exploited in the wild and whose silvicultural practices are not documented.

The methodological approach consisted of surveys carried out among 350 people in 10 villages, as well as field observations. The results showed that D. mespiliformis is well known to local populations (100% of respondents) who use it in six categories of use, with a broad consensus for use in medicine (Cs = 0.96), food (Cs = 0.33), constructions (Cs = 0.26) and as fuelwood (Cs = 0.24).

Les investigations ont été faites sur les fleurs de Cajanus cajan en vue d’estimer l’impact de l’activité de Dactylurina staudingeri sur la pollinisation, la production en gousses et en graines à Dang, en 2016 et 2017. Pour chacune de ces années, 540 boutons floraux ont été étiquetés sur 120 plantes réparties en quatre traitements: 120 fleurs laissées en libre pollinisation, 120 fleurs protégées des insectes, 200 fleurs protégées, puis découvertes, visitées exclusivement par D. staudingeri et de nouveau protégées et 100 fleurs protégées, découvertes et à nouveau protégées, sans visite d’insectes ou de tout autre organisme. Le taux de fructification, le nombre moyen de graines par gousse et le pourcentage de graines normales ont été comparés entre ces traitements. Sur 33 espèces d’insectes recensées, D. staudingeri était majoritaire avec 12,19% de 6037 visites. Cette abeille prélevait fortement le nectar et récoltait faiblement le pollen au niveau des fleurs de C. cajan. La vitesse moyenne de butinage était de 7,14 fleurs/min. Via l’efficacité pollinisatrice d’une visite florale, D. staudingeri a augmenté le taux de fructification de 14,71%, le nombre moyen de graines par gousse de 35,29% et le pourcentage de graines normales de 17,31%. La conservation des colonies de D. staudingeri à proximité des exploitations de C. cajan est recommandée pour assurer la hausse des rendements de cette culture et favoriser une bonne pratique de la méliponiculture dans la région.Abstract Investigations were made on the flowers of Cajanus cajan in order to estimate the impact of the activity of Dactylurina staudingeri on pollination and yields at Dang, in 2016 and 2017. For each of these years, 540 flowers buds labeled on 120 plants were divided into four treatments: 120 open-pollinated flowers, 120 bagged flowers, 200 flowers protected, then unbagged, exclusively visited once by D. staudingeri and rebagged, and 100 flowers bagged, unbagged and rebagged without insect or any other organism visit. The fruiting rate, the mean number of seeds per pod and the percentage of normal seeds were compared between these treatments. Among 33 insect species recorded, D. staudingeri was prominent with 12.19% of 6037 visits. This bee harvested intensely nectar and collected slightly pollen from C. cajan flowers. The mean foraging speed was 7.14 flowers/min. Through the pollinating efficiency of a single flower visit, D. staudingeri increased the fruiting rate by 14.71%, the mean number of seeds per pod by 35.29% and the percentage of normal seeds by 17.31%. The conservation of D. staudingeri colonies close to C. cajan farms is recommended to improve yields of the crop and to promote the good meliponiculture in the region.

The current study was conducted in four localities in the West region of Cameroon from May to September 2019, to know the pre-treatments made on given to beef hides before their use in different dishes, as well as the ingredients used in the preparation of pepper soup beef hides through household surveys. A total of 307 housewives were surveyed interviewed. The data was collected using a questionnaire and further analyzed using Sphinx Plus2 V5 software. Results showed that 54.6 to 71% participants consumed beef hides monthly. More than 50% participants purchased their beef hides at the butchery at a price varying between XAF 1,000 for 1Kg of uncleaned smoked beef hides and XAF 3,000 for 2Kg of clean smoked beef hides. The results also showed that there were five main stages in the preparation of beef hides and housewives had a greater preference of beef hides from the head and buttocks. The pre-cooking of beef hides was done between 180 and 240 minutes, with a quantity of water varying between 4 and 5 liters for 1 to 2Kg of beef hides, on the wood fire. “Eru” and “Yellow achu sauce” were cited as the main sauces in which beef hides were used at 95.40% and 85% respectively. Besides, more than 70% of housewives used a maximum of five ingredients for the preparation of pepper soup beef hides.

Background: Continuous cultivation without fertilizer application and soil erosion are responsible for plant nutrient depletion and yield decline of major food crops in Sub-Saharan Africa.Methods: Nutrient status of Calliandra calothyrsus, Leucaena leucocephala, Acacia angustissima and Cassia spectabilis were characterized. Field experiments were conducted over two years in the Western Highlands of Cameroon to evaluate the effects of the application of leaf biomass of agroforestry tree species and mineral fertilizers on maize yield performance. The residual effects on soil physicochemical properties were also investigated for umbric Cambisols of Babungo and ustic Oxisols of Bansoa. Ten treatments encompassing; sole leaf biomass of Calliandra calothyrsus, Leucaena leucocephala, Acacia angustissima and Cassia spectabilis, leaf biomasses combined with NPK fertilizer, sole NPK fertilizer and absolute control were laid in a randomized complete block design and replicated three times. Data were subjected to analysis of variance and the Duncan Test (p < 0.05) used for mean separation.Results: All the species characterized had nitrogen, polyphenol and lignin contents greater than 2.5 %, 5 % and 15 % respectively. Significant differences (p < 0.05) were observed among treatments on maize growth, productivity parameters and soil chemical properties for both soil types. The highest maize grain yields were recorded in plots amended with 1 t/ha of biomass of Calliandra calothyrsus or Leucaena leucocephala as well as1.5 t/ha of biomass of Acacia angustissima and Cassia spectabilis plus mineral fertilizer (50 N+ 37.5 P2O5 + 45 K2O) on both soils compared to other treatments.on umbric Cambisols and ustic Oxisols respectively.

La presente etude se propose d’etudier l’efficacite des extraits aqueux, ethanoliques et des huiles essentielles de Chromolaena odorata et d’Ageratum conyzoides sur le developpement des champignons responsables des pourritures des cabosses de cacaoyers dans les plantations villageoises d’Akonolinga, Dizangue et Tonga. Les extraits ont ete obtenus par maceration de 100 g de poudre de chaque plante. Les huiles essentielles obtenues par centrifugation ont ete fixees par le sulfate de sodium anhydre. Trois milieux de cultures V6, V8 et le milieu Pomme de terre – Dextrose - Agar (PDA) ont ete fabriques pour la culture des champignons associes aux cabosses. Les extraits et huiles essentielles de plantes ont ete prepares aux concentrations de 5 ; 10 ; 15 et 20 mg/ml. L’essai a ete conduit suivant un dispositif en blocs complets aleatoires avec 3 repetitions. La frequence d’isolement de chaque champignon par localite, la surface des lesions developpees sur les cabosses infectees et le pourcentage d'inhibition PI (%) des champignons pathogenes ont ete mesures et soumises a l’analyse de la variance (ANOVA). Les moyennes obtenues ont ete separees par le test de Duncan au seuil de probabilite 5%. Les resultats suivants ont ete obtenus : sur 8 especes isolees, seulement Phytophtora megakarya, Botryodiplodia theobromae et Colletotrichum gloeosporioides. ont ete pathogenes sur les cabosses saines. L’analyse statistique a montre des differences significatives (a P ≤ 0,05) entre les surfaces des lesions causees par ces champignons sur les cabosses entre le 4ieme, 7eme et 10eme jour apres inoculation (JAI) en fonction des especes fongiques testees.

Western Cameroon is one of the regions most in needs of innovative and healthy solutions for freshwater fish conservation. This study aimed at evaluating the socio-economical characteristics of fish smokers and technical factors on the species smoked in the Noun Division. A total of 91 fish smokers were chosen. The socio-economic data were on age, gender, religion, number of dependents, marital status, ethnic group, education level, economic activities, smoking goals and workforce. The results of this study showed that fish smoking is practiced mainly by women (70%) which is common in Sub Sahara Africa small scale fish sector. The smokers are aged from 20 to 50 years (80%), married (92.2%) and taking care of a family of 1 to 10 persons (80%). These smokers are Muslim (74%), belonging to the Bamoun ethnic group (81%). They were also involved in other activities: agriculture (29%) and trade (1%). About 67% of the sampled smokers’ population had an experience of more than 10 years in the domain. The Purpose of smoking was largely sales (97%) and subsistence (3%). Nile tilapia (Oreochromis niloticus) was the most smoked species (36%), followed by African catfish (Clarias gariepinus) with a proportion of 32%. The average quantity of fresh fish smoked was 110 kg/day/smoker, with Oreochromis niloticus being more produced (60±4.74 kg/day/smoker). With regard to the smoking techniques used, hygiene measures were poorly respected. The major constraints revealed by the survey were that freshwater’s traditional fish smoking activities in Noun Division are influenced by gender, economic and cultural background. There is a lack of technical support material and financial means. Any implications for future investigations on health and food safety will be suitable for fresh fish smokers and the entire consumers.

Diarrhea is one of the leading causes of death among children in low and low-middle income countries and the management of this pathology is still a problem in these regions. The water/ethanol extract of the pods of Cola anomala (KEO) has been shown to possess antimicrobial and antidiarrheal effects in Shigella flexneri-induced diarrhea, but whether KEO is active on the toxemic part of this diarrhea is unknown. This study was undertaken to evaluate the effects of KEO on the intestinal secretion and inflammation induced by intraperitoneal administration of lipopolysaccharide (LPS). KEO obtained by maceration in water/ethanol (1:1) was administered orally (25, 50 and 100 mg/kg of body weight) against LPS-induced diarrhea in mice. The mass of feces, the intestinal nitric oxide (NO) and prostaglandin (PGE2) contents as well as myeloperoxidase (MPO) activity were assessed. KEO was also tested on LPS-induced enteropooling in rats. In this experiment, the intestinal fluid and its electrolytes (Na+, K+ and Cl-) contents were determined as well as NO, PGE2, TNF-α and IL-1β levels in the small intestine homogenate. Indomethacin (5 mg/kg) was used as reference drug. KEO significantly (p < 0.001) reduced stools excretion, NO content and MPO activity in intestine but did not affect PGE2 in LPS-induced diarrhea. On the enteropooling model, KEO showed no effect on the intestinal fluid and electrolyte excretion, PGE2, TNF-α and IL-1β contents, but significantly (p < 0.05) reduced the NO production. This study suggests that KEO does not have antisecretory effect, but has anti inflammatory activities. It can be concluded that the anti-toxemic effect of KEO contributes less to its antidiarrheal activity in infectious diarrhea.

Montanoa tomentosa aqueous crude extract has been used for the last five centuries for the induction of labor, regulation of fertility, treatment of postpartum bleeding problems and to induce menses. In the present study, the hypothesis that the aqueous crude extract of M. tomentosa alleviates the metritis of dairy cows was tested. Adult Holstein Friesian dairy cows were diagnosed by gynaecological palpation as positive to postpartum metritis and single individual treatments of M. tomentosa or oxytetracycline were intra-uterine administered. Results showed that intrauterine administration of crude extracts of M. tomentosa alleviates the postpartum metritis without altering the ovarian activity. Present data reveal an emmenagogue action of the M. tomentosa extract in dairy cows that suffer postpartum metritis. Keywords : metritis, emmenagogues; dairy cows; Mexican plant; traditional remedy
