Abstract
Locust’s biocontrol requires identification of efficient bacterial strains able to be used against these ravagers. 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.
