Ce travail évalue l’importance socio-économique d’Irvingia gabonensis (Irvingiaceae) ou le manguier sauvage dans la région de l’Agnéby-Tiassa dans le sud de la Côte d’Ivoire. À cet effet, un inventaire de la population a été réalisé dans les zones agroforestières en particulier dans les cacaoyères afin de déterminer la perception de cette espèce par cinq groupes socio-culturels. Les différents usages et la rentabilité économique issue de la vente des amandes ont été également recherchés. Pour atteindre ces objectifs, la valeur d’usage ethnobotanique des différents organes, le taux de réponse des individus enquêtés et de la marge brute de commercialisation a été recherché. L’inventaire a permis de recenser seulement 26 pieds de I. gabonensis chez 35 paysans. Les travaux ont révélé deux usages principaux chez les Agnis, les Baoulés, les Groussis, les Malinkés et les Morés. Il s’agit de la consommation des amandes connue par 100% des enquêtés et de l’usage thérapeutique de l’écorce connue par seulement 10% de l’échantillon. Les investigations ont montré une marge brute de commercialisation moyenne de 27%. Des travaux complémentaires devront être réalisés pour valoriser d’avantage l’écorce et les feuilles. Aussi, nous préconisons le semis de graines ou le maintien de sauvageons dans les zones dégradées des cacaoyères en vue d’une gestion durable de cette ressource. SUMMARY This work assesses the socio-economic importance of Irvingia gabonensis (Irvingiaceae) or the wild mango tree in the Agnéby-Tiassa region in the south of the Ivory Coast. To this end, a population inventory was carried out in agroforestry areas, in particular in cocoa trees in order to determine the perception of this species by five socio-cultural groups. The different uses and the economic profitability resulting from the sale of almonds were also investigated. To achieve these objectives, the ethnobotanical use value of the different organs, the response rate of the individuals surveyed and the gross marketing margin were researched. The inventory identified only 26 stems of I. gabonensis among 35 farmers. The work revealed two main uses among the Agnis, the Baoulés, the Groussis, the Malinkés and the Morés. This is the consumption of almonds known by 100% of the respondents and the therapeutic use of the bark known by only 10% of the sample. Investigations showed an average gross marketing margin of 27%. Additional work will have to be made out to further enhance the bark and leaves. Also, we recommend the sowing of seeds or the maintenance of wildlings in degraded areas of cocoa trees with a view to sustainable management of this resource.

Objectif : Évaluer l’impact de la congélation sur certains paramètres physico-chimiques des tranches d’ignames de la variété kponan et faire une analyse sensorielle de quelques mets dérivés. Méthodologie et résultats : L’étude a été faite sur des tranches d’ignames prétraitées puis congelées pendant 3 mois. À Chaque mois, des échantillons ont été prélevés pour une analyse des paramètres physicochimiques et sensorielle des mets dérivés. La congélation n’a pas eu d’effet sur les teneurs en fibre, en protéine et en cendre. Cependant, au cours du premier mois, la matière sèche a augmenté de 5,59 %. Une augmentation des sucres réducteurs a été également observée. Tandis que la teneur en amidon a diminué de 5,54 %. A partir du deuxième mois, tous les paramètres physico-chimiques étudiés sont demeurés stables. Le profil sensoriel des mets dérivés a montré une bonne appréciation des caractéristiques sensorielles avec une forte élasticité (foutou) et une augmentation de la croustillance, de la fermeté et de la couleur (frite). Conclusion et applications des résultats : La technologie utilisée au cours de cette étude a permis de conserver la majeure partie des caractéristiques physico-chimiques et sensorielles de l’igname durant 3 mois. La production de tranches d’igname congelées doit être envisagée afin de palier le problème de conservation post-récolte, assurer la disponibilité tout au long de l’année permettant d’assurer la sécurité alimentaire et contribuer ainsi à la lutte contre la pauvreté en milieu rurale. Coulibaly et al., J. Appl. Biosci. 2021 Étude de la stabilité de quelques propriétés physico-chimiques des tranches d’igname congelées (Dioscorea cayenensis-rotundata cv Kponan) de Côte d’Ivoire et analyse sensorielle des mets dérivés 16322 Study of the stability of some physicochemical properties of frozen yam slices (Dioscorea cayenensis-rotundata CV Kponan) from Côte d'Ivoire and sensory analysis of derived dishes ABSTRACT Objective: Evaluate the impact of freezing on certain physicochemical parameters of yam slices of the kponan variety and make a sensory analysis of some derived dishes. Methodology and results: The study was performed on slices of pretreated yams and then frozen for 3 months. Each month, samples were taken for an analysis of the physico-chemical and sensory parameters of the derivative dishes. Freezing did not affect fiber, protein, and ash contents. However, in the first month, dry matter increased by 5.59%. An increase in reducing sugars was also observed. While the starch content decreased by 5.54%. From the second month, all the physico-chemical parameters studied remained stable. The sensory profile of the derived dishes showed a good appreciation of the sensory characteristics with high elasticity (foutou) and an increase in crispness, firmness, and color (fried). Conclusion and application of the results: The technology used during this study made it possible to conserve most of the physico-chemical and sensory characteristics of the yam for 3 months. The production of frozen yam slices should be considered in order to overcome the post-harvest conservation problem, ensure availability throughout the year, ensuring food security and thus contributing to the fight against poverty in the environment. rural.

Cette étude a été conduite à Zuénoula, dans le but d’évaluer la disponibilité et le niveau de connaissance des plantes sauvages comestibles pouvant servir d’alternatives aux populations locales et contribuer ainsi à leur valorisation. Pour cela, des investigations ethnobotaniques ont été réalisées à l’aide de fiches d’enquête dans 5 localités auprès de 368 individus. Les plantes et les organes comestibles récoltés ont été identifiés au Centre National de Floristique (CNF) d’Abidjan. Ainsi, les 76 espèces récensées appartiennent à 36 familles et 62 genres et représentent 32,34 % des plantes sauvages comestibles recensées en Côte d’Ivoire. Les Fabaceae (33,34 %) et les Malvaceae (22,23 %) sont les familles les plus rencontrées et sont majoritairement sous forme d‘arbres (38,16 %) et d‘herbes (26,32 %). Concernant les parties utilisées, ce sont les feuilles (38,85 %) et les graines (07,45 %) qui sont plus consommées en repas contrairement aux fruits (40,43 %) souvent consommés comme friandise au lieu de cueillette. Les populations (62,23 %) qui ont une bonne connaissance de la flore locale comestible sont aujourd’hui confrontées à la disparition progressive d‘espèces autrefois prisées comme Glyphaea brevis, Irvingia gabonensis et Telfairia occidentalis. Enfin, la consommation de Bixa orellana et de Gymnema sylvestre, espèces très utilisées dans l’alimentation humaine et la médecine en Asie, a pour la première fois été révélée en Côte d‘Ivoire. La poursuite de cette étude par des analyses des valeurs nutritives des espèces les plus sollicitées est vivement souhaitée en vue de leur valorisation au plan nutritionnel.  This study was conducted in Zuénoula with the aim of assessing the local people’s level of knowledge on wild edible plants and the availability of these plants to serve as alternatives for the local population and thus contribute to their development. To achieve this, botanical surveys were carried out in 5 localities involving 368 persons. Plants and edible organs collected were identified at the Centre National de Floristique (CNF) in Abidjan. All 76 species recorded belong to 36 families and 62 genera, and they represent 32.34% of wild edible plants identified in Côte d'Ivoire. Fabaceae (33.34%) and Malvaceae (22.23%) were the most common families and are mainly trees (38.16%) and herbs (26.32%). Concerning the part of the plants used, leaves (38.85%) and seeds (07.45%) were the most consumed in meals, which is contrary to fruits (40.43%) often consumed as sweets at the harvesting sites. The majority of the population (62.23%), which has a good knowledge of the local edible flora, is today confronted with the progressive disparition of species once sought after such as Glyphaea brevis, Irvingia gabonensis, and Telfairia occidentalis. This study reveals for the first time the consumption in Côte d'Ivoire of two plants' species, Bixa orellana and Gymnema sylvestre, widely used in human food and medicine in Asia, highlighting the great diversity of the local flora. Since the nutritional potential of these species has never been studied in Côte d'Ivoire, additional research on the most sought-after species is highly recommended for their nutritional valorization.

Southern blight caused by Sclerotium rolfsii Sacc. was observed on okra (Abelmoschus esculentus) cv. Clemson Spineless in January 2010 during a survey of vegetable fields in Rubbino, Côte d'Ivoire, which is one of the most important areas for vegetable production. Plants exhibited symptoms of a dark brown lesion on the stems near the soil line. Upper roots became light to dark brown, the lower leaves wilted, turned yellow, and a white mat of fungal mycelium developed on the stem lesion. Numerous, white, spherical sclerotia formed on the infected stem and on soil surfaces around the infected plants. Sclerotia (0.5 to 1.2 mm in diameter) later turned tan to dark brown and the entire plant wilted. Eleven fields, with a total of approximately 26 ha surveyed, were affected and disease incidence reached approximately 15% in the fields. Sclerotia were collected and the fungus cultured on acidified potato dextrose agar (PDA) plates. The fungus grew rapidly on PDA and the hyphae at the edge of the colonies were large straight cells with one or more clamp connections at each septum. Secondary and tertiary hyphae were slender and lacked clamp connections. Whitish sclerotia were observed on the mycelial mats 5 to 7 days after incubation, which later turned tan to brown when mature. The fungus was identified as S. rolfsii based on the characteristics of mycelia and sclerotia (1). Sclerotia produced on PDA were used to inoculate okra seedlings under greenhouse conditions at rates of 10, 20, and 30 sclerotia per plant. Sclerotia were placed just under the soil surface around the root of 4-week-old seedlings of okra cv. Clemson Spineless. Symptoms identical to those on field samples developed on all inoculated plants. S. rolfsii was reisolated from diseased plants and the identity was confirmed. S. rolfsii has previously been reported as causing disease in Côte d'Ivoire (2). To our knowledge, this is the first report of southern blight caused by S. rolfsii on okra in this country. Okra is an important vegetable crop in Côte d'Ivoire and therefore the occurrence of southern blight and susceptibility of okra cultivars to this disease needs to be taken into account in okra production.

Okra (Abelmoschus esculentus) is one vegetable crops most cultivated in Côte d'Ivoire. However, the plant is attacked by insects which caused important damage. This study was carried out to inventory entomofauna associated with okra crop and assess the damage caused by the pests. The insects were captured using pliers, sweep net by mowing technique and colored traps. Overall, a total of 61 species belonging to 36 families grouped into 10 orders were identified. During the plant cycle, 11602 insects were collected, including 3663 individuals at before stage flowering (31.57%); 3757 individuals at the flower bud stage (32.38%) and 4182 individuals at the flowering-fruiting stage (36.05%). Analysis of the occurrence frequency showed that Podagrica decolorata was ubiquitous in the crop, causing considerable damage to all organs of the plant. The damage assessment revealed that the defoliators, induced the highest average attack rates at all phenological stages. During the collections, six species (Rhinocoris albopilosus, R. rapax, R. bicolor, Hediocoris fasciatus, Cosmolestes pictus and Coranus sp) belonging to the family of Reduviidae were identified as predators of P. decolorata. This study therefore made it possible to identify P. decolorata as a major pest of okra and its predators, thus opening up a perspective of biological control as an alternative to chemical control.
