Abstract

The presence of the carrier and vector of Pectobacterium carotovorum (Jones) (Enterobacteriaceae) was found in Agave potatorum Zucc. (Asparagaceae) (larvae and adults of Scyphopphorus acupunctatus Gyllenhaal [Coleoptera: Curculionidae], larvae of Drosophila melanogaster Macquart [Diptera: Drosophilidae] and Hermetia illucens [L.] [Diptera: Stratiomyidae], and adults of Hololepta sp. [Coleoptera: Histeridae]) in Oaxaca, Mexico. Entomopathogenic fungi have been used as control methods to prevent the development of bacteria under laboratory conditions. After 5 d of inoculation, all the existing insects in the agave plants exhibited 98% of the countable growth of the bacterium, which led to the determination that the 4 species of insects are carriers and vectors of P. carotovorum. According to the final growth of the bacterium and the entomopathogenic fungi, the Beauveria bassiana (Bals.-Criv.) Vuill. (Cordycipitaceae) (E) strain at a concentration of 1.0 × 104spores per mL showed a difference of 57.2 mm. For this reason, it was considered the best strain to disable the growth of P. carotovorum.
