Seasonal abundance of Halyomorpha halys (Hemiptera: Pentatomidae) in habitats surrounding international ports and mobility and reproductive status of the insect during autumn dispersal period in South Korea

We monitored the seasonal abundance of Halyomorpha halys (Hemiptera: Pentatomidae) in forested areas near international ports and agricultural landscapes in South Korea from April to November in 2020 and 2021. Furthermore, flight capacity and reproductive status of field-collected H. halys adults during autumn dispersal period were evaluated. A total of 2,395 adults and 259 nymphs were collected, and population dynamics of adults showed similar patterns in forested areas near the ports and agricultural landscapes. Mean and maximum flight distances of adults collected from October to November, 2021, were 229 +/- 71 m and 2,802 m, respectively, and all adults were nonreproductive except one male.
