In this study, we analyzed the impact of an algerian strain of B. thuringiensis called TIM14 on the gut of Anacridium aegyptium. We observed that A.aegyptium infestation with TIM14 induced a lytic activity on the tegument and the cuticle followed by insect’s demise. In conclusion, our results suggest that the local B.thuringiensis strain TIM14 would be active through different enzymatic activities involving the chitinase that induces death of this orthoptera.enBacillus thuringiensis, Anacridium, aegyptiu; Gut, Biocontrol, Histopathology, Bacterium Strains, BiopesticidesArticle
