Monitoring population dynamics of Paranthrene tabaniformis with pheromone traps.
The results of 4 years of observations (1984-87) in poplar [Populus sp.] plantations 5 localities in N. Italy (Casale Monferrato, Sarmato, Bigarello, Migliaro e Palazzolo dello Stella) are reported, which aimed to evaluate the effectiveness of trapping by synthetic sex attractants as a monitoring tool for Paranthrene tabaniformis populations. Relations between male catches and female oviposition were investigated in the field. Chemical control strategies based on the observations (3 to 4 sprayings at 15-day intervals starting from mid-June) are confirmed.
