Abstract

Halyomorpha halys has expanded its invasive range in the USA southward into Georgia, but prior to 2018 established reproducing populations have not been reported in Florida. Yellow pyramid traps placed in peach orchards detected adult H. halys in 2016, 2017, and 2018, with the number of positive sites and specimens captured increasing each year. During 2018, nymphs and eggs of H. halys were observed at a peach orchard in Lake County, Florida. This represents the first evidence of a reproducing population of H. halys in Florida. The range expansion into Florida is the lowest latitude observed in the invasive range of H. halys, suggesting this temperate species may be able to overcome the barriers to range expansion posed by the temperature and photoperiod regimes found at lower latitudes.


Resumen

Halyomorpha halys ha expandido su rango invasivo en el sur de EE. UU. hacia dentro de Georgia, sin ser detectada o confirmada taxonomicamente poblaciones reproductoras previo a 2018 en Florida. Trampas piramidales amarillas localizadas en huertos de duraznos detectaron adultos de H. halys en 2016, 2017 y 2018, aumentando el número de adultos y sitios reportados año a año. En 2018, se observaron ninfas y huevos de H. halys en un huerto de duraznos en Lake County, Florida. Esto representa la primera evidencia de una población reproductora de H. halys dentro en Florida. La reciente detección en Florida representa la latitud más baja observada en el rango invasivo de H. halys, lo que sugiere que esta especie templada puede superar las barreras a la expansion del rango causado por la temperatura y el fotoperiodo en las latitudes más bajas.
