Comparative effectiveness of different types of aggregate pheromone traps for monitoring Brown marmorated stink bug – Halyomorpha halys (Stål) (Insecta: Hemiptera: Pentatomidae).
2022
The discovery of the aggregation pheromone has allowed researchers to design lures which attract the brown marmorated stink bug to the vicinity of the lure types location. For the monitoring three type of traps were Used, 1 – sticky-panel trap, 2 – Rescue trap (Sterling International), 3- Handmade trap constructed by using 1.5 liters plastic bottles. The first individuals of H.halys on all three types of traps were observed in April. The presence of the highest number of individuals (adults + nymphs) was observed in the June on the sticky trap. Each month, the number of captured H.halys by each type of trap differed significantly from each other (Chi-square - 81.09, df-46, P-value < 0.0011). Also, a significant statistical difference was observed in terms of H.halys caught by all three traps during the season (Chi-square - 69.14, df-12, P-value <0.0001).. There was also a significant statistical difference between the proportion of adults and nymphs in the captured insects. In particular, in April, May and October, the presence of nymphs was not observed in the traps at all, while more nymphs were observed in July and August . In this case, the sticky trap proved to be the most effective, in June, July, August and September, an average of 22, 45, 37, 14 nymphs were observed on the sticky trap, the rescue trap caught 5, 16, 19, 0, and the handmade trap caught 3, 14, 13, 0 (n=3) accordingly.
