The brown marmorated stink bug, Halyomorpha halys, is an invasive, herbivorous insect that has more than a hundred host plant species, including fruits, vegetables, and other agricultural plants, as well as ornamental trees and wild vegetation. This pest insect significantly damaged hazelnut orchards in Georgia. Along with regular insecticide applications, the effectiveness of the different management strategies is also evaluated. In this process, the efficiency of monitoring tools applied has particular importance to ensure reliable and valid data on the presence/absence of pest in hazelnut orchard. The present study aims to compare BMSB monitoring traps of three different designs. Two of them are dual-panel adhesive traps with different degree of adhesion (Trécé STKY and Trécé STKY 228), and the third one is a Rescue trap. All traps were baited with the same lure (Trécé Pherocon BMSB). The investigation has been conducted from May to September of 2019 in commercial hazelnut orchards located in Senaki municipality, Samegrelo region. A homogenous territory was selected for trap installment. The traps were checked on the presence of stink bug adults and nymphs separately fortnightly. As a result of the study, it was determined that Rescue traps are the most effective, and among sticky traps, the preference is given to STKY 228 with a higher degree of adhesion.
