Activité insecticide d’une souche marocaine de <i>Bacillus thuringiensis</i> sur la mouche méditerranéenne :<i> Ceratitis capitata (Wied.) (Diptera : Tephritidae)</i>

Abstract: Le présent travail consiste à étudier l'effet de deux types de toxines (δ -endotoxines et β -exotoxines) extraites à partir d'une souche de Bacillus thuringiensis (Bt A9) isolée d'un sol au Maroc sur la mouche Ceratitis capitata Wied (Diptera ; Tephritidae). les endotoxines de Bt A9 agissent sur la mortalité des larves et la longévité des adultes. par contre, les exotoxines présentent un effet notamment sur l'émergence des adultes. Les résultats de cette étude montrent que la souche Bt A9 présente une activité… Show more

“…In addition to spinosad, other biopesticides such as Azadirachtin and the fungus Beauveria bassiana have been registered in Morocco (Elaini & Mazih, 2018). Several studies were conducted in this country on the entomopathogens from the soils of argan forest, in order to exploit virulent strains of the bacteria Bacillus thuringiensis (Aboussaid et al, 2009(Aboussaid et al, , 2011 or the fungus B. bassiana against Medfly adults, pupae and larvae (Imoulan et al, 2011).…”

“…However, the estimated damage varies across countries. For instance, while losses from citrus and summer fruits could reach US $ 6 million in Morocco (Aboussaid, et al, 2009), in Egypt this number can ascend to US $ 177 million (Mahmoud, et al, 2017).…”

“…The financial loss due to this pest in these countries is estimated to be US $60-90 million per year, of which US $7-10 million per year is spent on insecticides (IAEA 1995). In addition, a survey conducted in Morocco, evaluated the annual losses caused by this fly on the main fruit and Citrus crops at 53 422 200 DH (Aboussaid et al 2009). In Tunisia, Boulahia-Kheder and Jerraya (2009) also consider this pest as the most important of several types of fruit, in particular, Citrus, peaches, figs and prickly pears and Jerraya (2003), estimates that the losses would be 90% of production in the absence of chemical treatments.…”
