Cocoa Tree

The cocoa tree is a very important plant in Côte d'Ivoire (formerly known as Ivory Coast) with a production of 2,15 million  tons. In spite of this performance, cocoa production is attacked by several pests of which the emerging ones are Pseudotheraptus devastans (Distant). These insects  attack  cherelles,  pods, gourmands and young shoots. This study aims to locate these pests and determine their importance in the different cocoa production areas. The device used is total  randomization. The leaching carried out in the orchard revealed the presence of P.devastans in all the cocoa producing districts. The means were 0,02 ± 0,00 to 2,35 ± 0,38 P. devastans  / tree.  The  districts of Sassandra-Marahoué, Comoé and Montagnes recorded  more  P.devastans.  However, the districts of Bas-Sassandra, Lagunes et Lacs had fewer P.devastans.

This article is an attempt to understand and analyze the difficulties encountered by agricultural cooperatives in the marketing of cola nuts. Despite the considerable capital generated by this sector, many difficulties are hampering the agricultural sector, which results in a sharp decline in the profits of cooperatives and producers. For the members, this is due to the lack or little commitment of the Ivorian State to revitalize this promising sector as is the case with the coffee-cocoa pair. In fact, the fact that foreign traders have direct access to growers in their production areas without going through a central structure, in particular the wholesale marketBouake, weakens domestic traders. Similarly, this situation prevents the Ivorian export circuit of Cola from having a substantial tonnage and allowing the entry of foreign currency into the country. All this contributes to devalue the label of the cola nut produced in Cote d'Ivoire.

If the culture of the cocoa in Côte d’Ivoire gives a great satisfaction concerning the production level, the quality of raw cocoa beans remains to be improved. One of the causes of this depreciation is the moulds development in beans. In order to identify responsible fungus, cocoa beens have been collected in the maine production areas which are the East, the Mid-West and the South-West, represented respectively by the localities of Abengourou, Oumé and Soubré. From collected beans, the fungus have been insulated and purified on PDA medium and then, they have been identified by observing their morphocultural and microscopic characteristics. The results show that 9 mushroom species belonging to 5 genera were identified in cocoa beans collected in the whole of the localities. There are Aspergillus, Penicillium, Fusarium, Curvularia and Streptomyces. Among them, the Aspergillus genus which is able to produce ochratoxine, was found with an appearance frequency of 86.30 %.

Breeding Habitats

Land-use practices such as agriculture can impact mosquito vector breeding ecology, resulting in changes in disease transmission. The typical breeding habitats of Africa’s second most important malaria vector Anopheles funestus are large, semipermanent water bodies, which make them potential candidates for targeted larval source management. This is a technical workflow for the integration of drone surveys and mosquito larval sampling, designed for a case study aiming to characterise An. funestus breeding sites near two villages in an agricultural setting in Côte d’Ivoire. Using satellite remote sensing data, we developed an environmentally and spatially representative sampling frame and conducted paired mosquito larvae and drone mapping surveys from June to August 2021. To categorise the drone imagery, we also developed a land cover classification scheme with classes relative to An. funestus breeding ecology. We sampled 189 potential breeding habitats, of which 119 (63%) were positive for the Anopheles genus and nine (4.8%) were positive for An. funestus. We mapped 30.42 km2 of the region of interest including all water bodies which were sampled for larvae. These data can be used to inform targeted vector control efforts, although its generalisability over a large region is limited by the fine-scale nature of this study area. This paper develops protocols for integrating drone surveys and statistically rigorous entomological sampling, which can be adjusted to collect data on vector breeding habitats in other ecological contexts. Further research using data collected in this study can enable the development of deep-learning algorithms for identifying An. funestus breeding habitats across rural agricultural landscapes in Côte d’Ivoire and the analysis of risk factors for these sites.

Aims: This study aims to determine merchantability of maize produced and stocked as grains, epis and spathes of maize in five departments of Côte d’Ivoire. Study Design: A total of 375 samples were collected at rate of 75 samples by department (Botro, Korhogo, Katiola, Agniblékro and Bondoukou). Then, the received samples were sent to the laboratory in order to analyse their merchantability. Place and Duration of Study: The collection of samples was carried out on grains, epis and spathes maize from February 2013 to January 2014. Then, the analyzes were carried out at the Biochemistry and Food Sciences Laboratory of the Félix Houphouët-boigny University. Methodology: The humidity was determined by drying until constant weight when the losses and damages of grains have been quantified by counting and weighing. Results: The results show that for maize grains, humidity levels vary from 8.59±0.11% to 14.18±0.52%. Concerning epis of maize, humidity levels are between 9.85±0.23% to 13.02±0.32%. For maize spathes, humidity levels fluctuate between 11.16±0.29% to 14.17±0.32%. The damages varies from 5.01±2.64% to 19.35±2.00% for maize grains, 9.05±5.27% to 21.29±7.17% for epis and 17.95±1.13% for spathes. As regards weigh losses, proportions of grains, epis and spathes are between 1.53±1.17% and 5.10±0.97%, 2.43±1.70% and 6.54±1.79% and 2.76±1.18% and 5.11±2.65%, respectively. Conclusion: A significant variability from one department to another can be noticed at level of maize quality regardless the type of maize. The merchantability of maize seems to be tied to post-harvest treatments (drying), type of storage (epis, grains and spathes) and structure of storage.

The area planted for vegetable production is increasing in Côte d'Ivoire while crop yields are decreasing due to low soil fertility, poor application of mineral fertilizers and poor plant development due to pest pressure. The trial carried out at the experimental site of the University Jean Lorougnon Guédé of Daloa, Central-Western Côte d'Ivoire, aims at evaluating the potential of vermicompost to reduce the attacks of the Rhizoctonia sp fungus on the tomato crop and increase its production. The trial was carried out using the Fischer randomized block design where four treatments were repeated four times. Four substrates, composed of mixtures of soils and doses of vermicompost (0, 20, 40 and 60 t/ha), inoculated with the fungus, were used for the cultivation of tomato in pots. Agronomic and phytosanitary parameters were evaluated on tomato plants at the end of the trial. The results showed that the production increased with the addition of vermicompost and this, the higher the dose of vermicompost added. The health of tomato plants was also improved by the reduction of Rhizoctonia sp attacks, especially with the 60t/ha dose, for which the disease severity and incidence indices were the lowest, 15% and 14%, respectively, against 41% and 38% obtained with the control. Vermicompost could be used to control fungal diseases of tomato and improve its production.
