Abstract

Trapping of Lymantria monacha L. (Lep., Lymantriidae) in various pheromone traps

Five type of traps containing the Disparlure-pheromone were tested on the nun moth in two regions of Bohemia. Two of these traps, with the sticky inner surface of 330 and 400 qcm, were made by the Zoecon Corporation, the other three were plates with one stikcy side (2500, 5000 and 10 000 qcm).

Catches on the 10 000 qcm plates were 11 times higher than in the traps with a small sticky surface. This finding indicates that catches in small traps do not give an accurate picture of the population density of males throughout their flight. This could be explained by a high concentration of the pheromone in the immediate vicinity of the trap, preventing the attracted males from finding the source of attraction in the trap.
