Technical Abstract: We collected a native North American species, Phyllocnistis insignis (Frey & Boll) (Lepidoptera: Gracillariidae), in traps baited with a 3:1 blend of (Z,Z,E)-7,11,13-hexadecatrienal (triene) and (Z,Z)-7,11-hexadecadienal (diene), 2 components of the sex pheromone of the invasive citrus leafminer, P. citrella Stainton. No moths were caught in unbaited traps. Phyllocnistis insignis moths were found in pheromone-baited traps year round with a peak flight in May. In 3 trials designed to evaluate mating disruption of P. citrella, application of triene and/or a 3:1 blend of triene and diene disrupted catch of male P. insignis. These data suggest that efforts to disrupt mating of P. citrella may influence non-target populations of the congeneric leafminer species, P. insignis.
