Alternative survey methods for the emerald ash borer
Keywords:
Agrilus planipennis, green multi-funnel traps, wet cup, dry cup, trap check intervalAbstract
As part of an ongoing project to improve survey and detection for the emerald ash borer, Agrilus planipennis, several field assays were conducted to (1) determine how often traps need to be checked during a given field season, and (2) compare the effectiveness of traps with “dry” (with insecticidal strips or internal funnel) vs. “wet” (with propylene glycol surfactant) collection cups. There were no significant differences among any of the trap check intervals or the trap methods tested. This will provide new tools to surveyors, and allow them more flexibility as they survey for this invasive pest.
Sumario
Se realizaron varios ensayos de campo como parte de un Proyecto en marcha para mejorar el sondeo y la detección del barrenador esmeralda del fresno, Agrilus planipennis para (1) determiner con qué frecuencia se deben revisar las trampas durante una temporada de campo determinada, y (2) comparar la efectividad de trampas “secas” (con tiras de insecticida o embudo interno) vs. “húmedas” (con surfactante de propilenglicol). No hubo diferencias significativas entre ninguno de los intervalos de control de trampa o los métodos de trampa probados. Estos resultados proporcionan nuevas herramientas a los topógrafos y les permitirá una mayor flexibilidad a medida que realizan el sondeo para la detección de esta plaga invasiva.
