La mineuse de tomate, Tuta absoluta est un micro-lépidoptère qui se nourrit préférentiellement sur la plante de tomate. Les larves du bioagresseur s’attaquent aux différentes parties aériennes de cette plante. Elles creusent des galeries dans les feuilles et les fruits et peuvent occasionner des pertes de rendement de 80 à 100% dans une culture de tomate. En effet, la mineuse est originaire de l’Amérique du sud, mais a été détectée sur le continent Africain en 2008. Dix ans après, cette espèce invasive a été signalée dans la partie septentrionale du Bénin, mais depuis peu de données existes sur son expansion et sa répartition dans le Sud du Bénin. Le présent travail tente de clarifier la présence et la répartition de la mineuse au Sud du Bénin en vue de mettre en place une stratégie de gestion de ce dernier. Une enquête détaillée a d’abord été réalisée auprès de 90 producteurs dans le Département du Couffo sur les pratiques culturale, le niveau de connaissance des producteurs sur la mineuse de tomate. Ensuite, des pièges a phéromone ont été utilisés pour investiguer la présence et l’évolution de la population de T. absoluta (du 25/04/2021 jusqu’au 30/06/2021) sur 5 champs identifiés dans chacun de trois villages dont Gbakonou, Kpevidji, et Zohoudji. Il ressort que, les producteurs enquêtés produisent la tomate sur des parcelles de superficie inférieurs à 1 hectare. Ces dernières sont parfois louées pour une ou deux saisons consécutives. 91% des enquêtés reconnaissent les insectes comme des facteurs qui affectent la production de la tomate. 92.5% des enquêtés ont reconnus qu’ils utilisent uniquement les pesticides chimiques pour lutter contre les insectes et qu’ils pulvérisent plusieurs fois les plants de tomate avant la récolte. Cependant, 85.60% des enquêtées ne connaissent pas la mineuse de tomate et 6.70% des enquêtés ont mentionnés avoir rencontré ses dégâts dans leurs champs de tomate, contre 7.80% qui ont mentionnés qu’ils ne font généralement pas attention aux types de ravageurs dans leur champ. Toutefois, les adultes de T. absoluta ont été capturés dans chaque champ dans chacun des villages. Les nombres moyens d’adultes capturés par semaine par piège varient dans le Département (GLM : χ2=6514.9, df=29, p < 0.001). De même, les nombres moyens d’adultes capturés par champ (GLM : χ2=6357.4, df=14, p < 0.001) et par village (GLM : χ2=6045.8, df=2, p < 0.001) varient dans cette partie du Bénin. Le plus faible nombre moyen d’adultes capturés par village a été noté dans le village de Zohoudji, 120.8±76.23, alors que le nombre moyen le plus élevé est de 1315.4±208.45 observés à Gbakonou. Les chiffres les plus élevés des nombres moyens d’adultes mâles ont été observés en juin à Zohoudji, fin mai et fin juin à Gbakonou, et mi-mai et début juin à Kpevidji.

A valuable new reference on insect behavior, this exceptional new text delves into the primary sensory communication system used by most insects -- their sense of smell. This important text covers how insects produce pheromones and how they detect pheromones and plant volatiles. Since insects rely on pheromone detection for both feeding and breeding, a better understanding of insect olfaction and pheromone biosynthesis could help curb the behavior of pests without the use of harmful pesticides and even help to reduce the socio-economic impacts associated to human-insect interactions.*
