Comparison of different pheromone traps for monitoring of click beetle Agriotes ustulatus (Coleoptera Elateridae)

Abstract

The effectiveness of two trap types (YATLORf and VARb3 with CSALOMON® sex pheromone bait) for monitoring click beetle Agriotes ustu latus was compared near Karcag (East Hungary) in 2016. Additionally effectiveness of YATLORf traps placed on ground and placed on a 25 cm high mound was also compared. Contrary to our expectations traps caught very few individuals thus our study could provide only preliminary results. Between traps and methods there were not significant differences but YATLORf traps placed on mounds caught more individuals than others. The swarming imagos of A. ustulatus were also detected two weeks earlier in 2016 than as usual. To prove the effect of the way of usage on the effectiveness of YATLORf traps new studies should be made.
