Descripción
This study centers in a survey conducted to find Rhynchophorus palmarum (L) and R. ferrugineus (Olivier) (Coleoptera: Curculionidae), two invasive species of palm trees. The study was performed in the Rio Grande Valley in south Texas, and near the borderline of the state of Tamaulipas in Mexico. A total of 40 traps were inspected biweekly from 26 September 2011 to 20 September 2012. Only, two specimens of R. palmarum were found and identified next to a commercial palm plantation on 11 March and 5 May 2012 near the city of Alamo, TX; and none R. ferrugineus was found throughout the entire duration of the study. Nematodes of the genus Rhabditis, Poikilolaimus, Pseudodiplogasteroides (Family Aphelenchidae) were found in the two R. palmarum weevil specimens.
