Abstract

Agave cupreata is a species impacted by soft rot caused by Scyphophorus acupunctatus (agave weevil) described as a vector of the disease, but the diversity of culturable bacteria that reside in the digestive tract of the weevil, which can be a source of infection for the weevil, is unknown. already described. Therefore, we collected weevils in three communities, in which we cultured the digestive tracts and selected 20 strains in which we evaluated their microbial metabolism, their antibiotic resistance profile and their ability to cause symptoms. in pieces of agave leaf and stem under sterile conditions, and after 21 days signs were found on the stem and the same inoculated strain was re-isolated in two of them. The strains causing the symptoms were identified; Pseudomonas putida, Serratia marcescens, Kluyvera cryocrescens, Aeromona salmonicida, with resistance to beta-lactam antibiotics. These data are important to understand that there are more microorganisms that cause signs in the agave and that the weevil is one of the main vectors, and we must do more detailed investigations to confirm the results to apply control measures for the vectors and bacteria that cause the disease decay smooth in A. cupreata.
