Passive trap for monitoring codling moth (Lepidoptera: Tortricidae) flight activity

A new passive trap, constructed of rigid, clear plastic panes (0.3 m by 0.3 m), coated with an STP Oil Treatment film as an adhesive, was developed for monitoring codling moth, Cydia pomonella (L.), movement within and between orchard canopies. Tests showed that the trap was effective in recapturing released codling moth adults, that the adhesive was not attractive to moths, and that the adhesive was still effective after remaining on a trap for 1 wk in the field. Field experiments demonstrated that the passive pane-trap method is as efficient for catching moths as molasses-baited traps but that it is less efficient than pheromone-baited and blacklight traps placed in an orchard at equal densities. However, total capture of moths in plots treated with pane traps increased with trap density
