Field evaluation of a synthetic female sex pheromone for the leafmining moth Phyllocnistis citrella (Lepidoptera: Gracillariidae) in Florida citrus. Florida Entomologist. 89:274-276. Interpretive Summary: Recently discovered attractants based on three compounds (two major and one minor component) produced by female citrus leafminer moths, Phyllocnistis citrella, that attack citrus were tested for the first time against Florida populations of the moth. Traps that were baited with the two major components were as effective as traps baited with all three components. The synthetic lures attracted significantly more male moths than unbaited traps. The height at which traps were located on orange trees did not affect the number of male moths caught.
Technical Abstract: Traps baited with a binary mixture in the ratio of 30:10 of two EAG-active compounds, (Z,Z,E)-7,11,13-hexadecatrienal and (Z,Z)-7,11-hexadecadienal attracted significantly more moths of the leafmining moth P. citrella compared with unbaited traps in a Florida citrus grove. The addition of a third EAG-active compound, (Z)-7-hexadecenal, did not increase trap catch. Trap height, measured at 0.7, 1.3, and 2 m did not significantly affect trap catch.
