Microlepidoptera caught in traps baited with lures containing pear ester and acetic acid in Hungary
2016
The present research was undertaken to screen for field activity of ethyl-(E , Z)-2,4-decadienoate (pear ester, PE), acetic acid (AA) and the blend of this two components (PEAA) at locations, where high diversity of microlepidopteran species was presumed. By tendency of relative catches, microlepidopterans captured could be divided into two groups: in the first group the PEAA blend resulted in higher catches than single components (Hedya nubiferana , Ypsolopha scabrella and Notocelia trimaculana), while in the second group (Archips rosana , A. xylosteana , Ptycholoma lecheana and Tortrix viridana) only the presence of AA was responsible for attractivity. In all species, both male and female specimens were caught. This result indicates a potential way to optimise female-targeted lures based on PEAA or AA for all these microlepidopterans that are all recorded as pests. On the other hand, the capture of the above moths in the traps raises the need for some taxonomic knowledge in evaluating captures in PEAA-baited traps currently use in agricultural practice for codling moth monitoring.
