Abstract

Pheromone traps for monitoring Gypsonoma aceriana and Paranthrene tabaniformis populations.

Abstract

Trials with two pheromone traps (one pagoda-shaped - Traptest Agrimont, the other D-shaped - Delta Trap IOB) in a young poplar [Populus sp.] plantation in N. Italy showed that the pagoda trap, which had a larger sticky surface (400 cm2 vs. 170 cm2 for the D-shaped trap), was better able to retain the number of male insects trapped during peak flight periods. Traps were recharged and insects collected every 4 weeks during May-September. The pagoda trap was also particularly suitable for larger insects, such as Paranthrene tabaniformis, whereas the D-shaped trap would be sufficient for monitoring of Gypsonoma aceriana.
