This study aimed to isolate and characterize bacteria from the codling moth,
Cydia pomonella
(L.) (Lepidoptera: Tortricidae), and determine their virulence to its larvae. A total of 16 bacteria were isolated from larvae belonging to different instars. Based on morphological, biochemical, physiological, and molecular studies, the bacterial isolates were identified as
Pseudomonas
sp. (Cp1, 3, 5, and 13),
Corynebacterium
sp. (Cp2),
Bacillus
sp. (Cp4, 7, 9, 10, 12, and 15),
Pectobacterium carotovorum
(Cp6),
Paenibacillus
sp. (Cp8),
Bacillus megaterium
(Cp11),
Bacillus pumilus
(Cp14), and
Terribacillus saccharophilus
(Cp16). It was also determined the virulence of these isolates, where the highest potential activity was obtained by
Bacillus
sp. Cp9, with (76%) mortality. These results could be beneficial for future biocontrol programs of
C. pomonella
