Relationship of Within-tree Placement of the Pheromone Trap to Codling Moth 1 Catches

Pear ester based lures for the codling mothCydia pomonellaL. — A summary of research efforts in Hungary

“…From results of the present study it is strongly suggested that pear ester+acetic acid baited traps be suspended from the highest branches of the tree even if this makes inspecting the traps more awkward. It has been reported previously also for pheromone traps that they catch more codling moths when set high in the canopy (Riedl et al, 1979). …”

Passive Trap for Monitoring Codling Moth (Lepidoptera: Tortricidae) Flight Activity

“…Total capture of Discussion Active trapping methods for codling moth adults include pans containing fermenting baits (usually molasses), light traps, and pheromonebaited traps. One or more of these methods have been used to provide information regarding the position of codling moth activity within a tree's canopy (Yothers 1927, McNally & Barnes 1981, Riedl et al 1979, Howell et a1. 1990), seasonal activity patterns (Spuler 1930), moth movement (Worthley 1932), timing of flight (Batiste et a1.…”

Population monitoring of the pine processionary moth (Lepidoptera: Thaumetopoeidae) with pheromone-baited traps

“…Increased captures with pheromone traps placed at the upper crown of the tree have been reported in several other moth species, including the oak processionary moth (Breuer et al, 2003), the leopard moth (Pasqualini and Natale, 1999), and the codling moth (Riedl et al, 1979). This pattern may reflect a preference of males for flying towards the top of tree silhouette (Demolin, 1969), or a greater release of pheromone molecules above the tree canopy (Breuer et al, 2003).…”
