N1 - Funding Information:
We would all like to thank Bill Lingren, Trécé Inc., Adair, OK, for providing the experimental septa and membrane lures used extensively in these trials. We also appreciate the funding made by Fondo de Desarrollo Científico y Tecnológico (FONDECYT) Grant 3140285 to WBP and partial funding from Millennium Nucleus Centre in Molecular Ecology and Evolutionary Applications in Agroecosystems and Inciativa Cientifica Milenio NC 120027 to EFC. We also thank Steve Schoof and Lindsay Stump of NC State University, Raleigh, NC, for technical assistance in the NC study. In Uruguay, we would like to thank the staff of the experimental station Wilson Ferreira Aldunate of the Instituto Nacional de Investigación Agropecuaria including Gonzalo Vázquez and Gastón Tejera who participated in the field activities and Mariana Silvera who helped with insect counts in the laboratory. Finally, in Italy, we would like to thank Domenico Abeti of Agrintesa and the other IPM technicians who have indicated the peach orchards in which to perform the studies. We would like to thank Rodney Cooper, ARS, Wapato, WA; Cesar Gemeno, University of Lleida, Spain; and Valentino Giacomuzzi, Free University of Bozen-Bolzano, Italy, for their careful reviews of our rough draft.

N2 - Male and female moth catches of Grapholita molesta (Busck) in traps were evaluated in stone and pome fruit orchards untreated or treated with sex pheromones for mating disruption in Uruguay, Argentina, Chile, USA, and Italy from 2015 to 2017. Trials evaluated various blends loaded into either membrane cup lures or septa. Membrane lures were loaded with terpinyl acetate (TA), acetic acid (AA) and (Z)-3-hexenyl acetate alone or in combinations. Two septa lures were loaded with either the three-component sex pheromone blend for G. molesta alone or in combination with codlemone (2-PH), the sex pheromone of Cydia pomonella (L). A third septum lure included the combination sex pheromone blend plus pear ester, (E,Z)-2,4-ethyl decadienoate (2-PH/PE), and a fourth septum was loaded with only β-ocimene. Results were consistent across geographical areas showing that the addition of β-ocimene or (Z)-3-hexenyl acetate did not increase moth catches. The addition of pear ester to the sex pheromone lure marginally increased moth catches. The use of TA and AA together significantly increased moth catches compared with the use of only one of the two components. Traps with the TA/AA lure outperformed the Ajar trap baited with a liquid TA plus sugar bait. The emission rate of AA was not a significant factor affecting the performance of the TA/AA lure. The addition of TA/AA significantly increased moth catches when combined with the 2-PH lure. The TA/AA lure also allowed traps to catch both sexes. Catch of C. pomonella with the 2-PH lure was comparable to the use of codlemone; however, moth catch was significantly reduced with the 2-PH/PE lure. Optimization of these complex lures can likely further improve managers’ ability to monitor G. molesta and help to develop multispecies tortricid lures for use in individual traps.
