Abstract

Field experiments conducted in three Georgian localities from July to October 2025 evaluated two pheromone types and trap designs for monitoring Halyomorpha halys Stål, 1855 (Hemiptera: Pentatomidae). Captures of adults and nymphs were analyzed using two-way ANOVA. Pheromone type A consistently produced higher catches than type B across rocket and sticky traps, while locality effects varied between trap types. Population peaks occurred in late August-September, with nymphs disappearing by October and adults dominating late-season captures. Results indicate strong seasonal dynamics and regional differences in abundance. Overall, pheromone type A proved more reliable for field monitoring, supporting its use in integrated pest management programs against this invasive species in Georgia (Sakartvelo).
