The mango tree in central and northern Benin: damage caused by fruit flies (Diptera Tephritidae) and computation of economic injury level

Abstract: The mango tree in central and northern Benin: damage caused by fruit flies (Diptera Tephritidae) and computation of economic injury level.Abstract --Introduction. In the southern Sudanian zone of Benin, fruit flies are major pests and responsible for considerable yield losses in mango production. The two main species of economic importance affecting mango trees in Benin are Ceratitis cosyra and Bactrocera invadens. During the 2006 crop year and across seven main cultivars, losses stood at 17% in early April an… Show more

“…Thus, all fruit fly species that have an economic impact on mango production are included. The EIL calculation is therefore an indicator for initiating pest control [using spinosad (GF-120), for instance] at the right time and for neutralizing any large increase in the fly populations [36]. According to our previous activities in the larger mango production basin of central Benin, treatments with GF-120 should be launched at least five weeks [37] before the pre-maturity stage of earlier mango cultivars.…”

“…Bactrocera invadens is present in mango orchards of the Lake Victoria Crescent all year round, and at levels that far exceed economic thresholds set in other parts of the world [26]. Bactrocera invadens population and infestation levels progressively rise as fruit matures and ripens, followed by a rapid decrease in population numbers after harvest.…”

“…La hausse des captures de B. dorsalis dans les vergers est aussi imputable au cycle biologique naturel de l'insecte dont les niveaux de populations augmentent avec l'arrivée de la saison des pluies (White et Elson-Harris, 1992). Par ailleurs, les pièges créent des épicentres d'attraction pour les mâles qui y convergent souvent à partir de longues distances (Vayssières et al, 2009). En outre, l'abondance des mouches observées dans les vergers témoins dans le mois de Mai ou dans les trois premières semaines serait due à la période de forte fructification et des premières pluies.…”

“…Toutefois, le fait qu'il n'y ai pas de différence significative de protection des vergers entre les différents produits, révèle l'efficacité de l'utilisation des appâts alimentaires dans la protection des vergers de manguiers. Vayssières et al (2009) ont aussi démontré dans leurs travaux, que l'application du Success Appat® dans les vergers de manguiers du Bénin, a permis d'obtenir une différence hautement significative entre les vergers non traités et les vergers traités (16,97 ± 1,96 pupes/kg de fruits pour les parcelles non traitées et 3,17 ± 0,61 pupes/kg de fruit pour les parcelles traitées au Success Appat® en 2006 et 34,5 ± 3,53 pupes/kg de fruit pour les parcelles non traitées contre 3,67 ± 0,67 pupes/kg de fruit pour les parcelles traitées en 2007).…”
