Comparative effectiveness of different types of aggregate pheromonetraps for monitoring Brown marmorated stink bug - Halyomorpha halys (Stål) (Insecta: Hemiptera: Pentatomidae)

Abstract

The discovery of the aggregation pheromone has allowed researchers to design lures which attract the brown marmorated stink bug tothe vicinity of the lure types location. For the monitoring three type of traps were Used, 1 – sticky-panel trap, 2 – Rescue trap (SterlingInternational), 3- Handmade trap constructed by using 1.5 liters plastic bottles. The first individuals ofH.halyson all three types of trapswere observed in April. The presence of the highest number of individuals (adults + nymphs) was observed in the June on the stickytrap. Each month, the number of capturedH.halysby 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 ofH.halyscaught by all three traps during theseason (Chi-square - 69.14, df-12, P-value <0.0001). There was also a significant statistical difference between the proportion of adultsand nymphs in the captured insects. In particular, in April, May and October, the presence of nymphs was not observed in the traps atall, 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, andthe handmade trap caught 3, 14, 13, 0 (n=3) accordingly.
