Évaluation des dégâts de Analeptes trifasciata (Coleoptera : Cerambycidae) sur les anacardiers dans les régions du Béré et de l’Iffou (Côte d’Ivoire)

Objectif : L’objectif de l’étude était d’évaluer les dégâts et de fournir une base de données relative à Analeptes trifasciata, ravageur de l’anacardierMéthodologie et résultats : Pour évaluer les dommages de Analeptes trifasciata, des prospections ont été menées dans des vergers d’anacarde des sous-préfectures de Bouandougou, Ouellé et Tiéningboué d’avril à mai 2015. Il ressort de ces prospections que les dégâts du Cerambycidae sont observés dans toutes les plantations visitées. Cet insecte occasionne d’importantes pertes de branches d’anacardiers allant de 1,20 ± 0,42 à 3,90 ± 1,20 avec des diamètres pouvant atteindre 16,60 ± 0,70 à 19,10 ± 0,87 cm. Le stade phénologique le plus sensible et attractif des anacardiers aux attaques du Cerambycidae est la floraison, coïncidant avec la fin de la saison des pluies. Les branches sectionnées par le ravageur sont éliminées par brûlage respectivement à 30%, 0% et 20% par les producteurs de Bouandougou, Ouellé et Tiéningboué.Conclusion et application : Il ressort de cette étude que Analeptes trifasciata cisaille les branches de l’anacardier à la floraison en début de saison sèche. On peut conseiller aux producteurs de toujours bruler les branches qu’ils entassent dans les plantations afin d’éliminer oeufs, larves et adultes du ravageur. Mais l’utilisation de la lutte mécanique consistant à tuer le ravageur à l’aide de machette ou d’une houe est aussi important et pour cela ils doivent parcourir quotidiennement les champs à la recherche du ravageur.Mots-clés : Anacarde, Analeptes trifasciata, Cerambycidae, dégâts, Côte d’Ivoir

Bushmeat consumption in large urban centres in West Africa

Bushmeat consumption in large Sub-Saharan African cities is perceived as a major threat to the conservation of many species because their considerable population sizes can generate a significant demand for bushmeat. The study of the effect of age, sex and geographic location in bushmeat eating in African cities may offer valuable insights on which population groups to target in behaviour change campaigns. Using 2,040 interviews in six West African cities from four countries, in forest and savannah settings, we analysed the differences between age and sex in people’s frequency of bushmeat consumption. Overall, we found similar patterns in all sampled cities. As many as 62.2 % males and 72.1% females replied that they ‘would not eat bushmeat at all’, though only 12.8% males and 8.8% females mentioned they regularly ate bushmeat. Younger generations of both sexes answered that they ‘would never eat bushmeat’ more often than older age groups, independently of their city of origin. These trends are encouraging though further research needs to be undertaken to find out whether bushmeat volumes consumed in cities are unsustainable and having a serious impact of prey populations
