Sex pheromone trapping of Cossus cossus (L.) and Zeuzera pyrina (L.) (Lepidoptera, Cossidae)

In Italy European Goat Moth (ECM) and Leopard Moth (LM) can infest orchards as well other trees. Experiments were conducted during three years in a plantation of walnut trees for wood production, to evaluate capture efficiency in relation to: 1) different trap types (funnel with or without different kinds of buffles); 2) trap position; 3) effect of multi-baited traps. The number of captured individuals was studied using log-liner analysisi and for both species the tree-factor interactions were showed. Traps located over the tree canopy were the most efficient for EGM and Lm males. There was a difference in males captures of both species related to type of trap. The traps without baffles showed the highest capture rate of EGM while the multi-baited with thin baffles showed the highest capture rate of LM
