Abstract

Several Persian lime trees were found to exhibit dieback and yellowing during monitoring of the intensity of Huanglongbing disease on a 6-year-old commercial Persian lime orchard in San Rafael, Veracruz, Mexico, between August and October 2022. During the examination of the trees, we discovered small holes on the bark of the main stem and lower branches, significant cracking of the bark, and beetles crawling on the surface. Removal of the bark on the crevices showed the presence of larvae and adults plausibly feeding from the inner bark tissue. Phloeonemus interruptus (Coleoptera: Zopheridae) adults were found. Although it is unknown whether P. interruptus will become invasive, this study confirmed that it is associated with Persian lime trees. Thus, this serves as a bellwether to warn of the potential direct damage or transmission of fungi or oomycetes, such as those in the genera Lasiodiplodia and Phytophthora. To the best of our knowledge, this is the first report of the association of Phloeonemus interruptus with Persian lime (Citrus latifolia Tan. Rutaceae) in the central region of Veracruz, Mexico.

Durante el monitoreo de la intensidad de la enfermedad de Huanglongbing en un huerto comercial de limón persa de 6 años en San Rafael, Veracruz, México, entre agosto y octubre de 2022, se encontró que varios árboles de limón persa presentaban muerte regresiva y amarillamiento. Mediante la examinación de los árboles, se observaron pequeños agujeros en la corteza del tallo principal y las ramas inferiores, grietas significativas en la corteza y escarabajos arrastrándose por la superficie. La eliminación de la corteza de las grietas mostró la presencia de larvas y adultos que aparentemente se alimentaban del tejido de la corteza interna. Se encontraron adultos de Phloeonemus interruptus (Coleoptera: Zopheridae). Aunque se desconoce si P. interruptus se volverá invasivo, este estudio confirmó que está asociado con los árboles de limón persa. Por lo tanto, esto sirve como un indicador para advertir sobre el posible daño directo o la transmisión de hongos u oomicetos, como los de los géneros Lasiodiplodia y Phytophthora. Hasta donde sabemos, este es el primer reporte de la asociación de Phloeonemus interruptus con limón persa (Citrus latifolia Tan. Rutaceae) en la región central de Veracruz, México.
