“…A number of laboratory and field studies have evaluated various host plant volatiles for G. molesta and achieved variable results. For example, either β‐ocimene or ( Z )‐3‐hexenyl acetate alone or in various HPV blends was found to increase moth catches (Il’ichev et al., ; Knight et al., ; Natale et al., ; Piñero & Dorn, ), or provided variable results, such as β‐ocimene improved the performance of TAS‐baited traps (Knight et al., ); but pear ester plus β‐ocimene did not improve the 2‐PH lure (Knight, Cichon, et al., ). Similar to this later study, we found that neither β‐ocimene nor ( Z )‐3‐hexenyl acetate affected moth catches when used with either 2‐PH or TA/AA lures, and likely neither volatile will be developed further through our trials.…”

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.

“…(Hansson et al, 1989) and Heliothis subflexa (Guenée) (Baker et al, 2004) relatively smaller percentages of unresponsive ORNs were reported in sensilla trichodea (11% and 2%, respectively). Male G. molesta respond behaviorally to plant volatiles (Varela et al, 2011a;Il'ichev et al, 2009;Lu et al, 2013), so some of their unresponsive ORNs could be tuned to plant volatiles. In addition, ORNs unresponsive to pheromone compounds could be used to detect pheromone compounds from other species that inhibit male G. molesta response to the female pheromone, such as Z6-12:Ac and Z10-14:OH (Guerin et al, 1986;Tòth et al, 1991), as happens in other species (reviewed in De Bruyne and Baker, 2008).…”

“…The first field study reporting attractive host plant volatiles for G. molesta found a 1 : 2 : 2 ratio of ( Z )‐3‐hexenyl acetate, ( E )‐ β ‐ocimene and ( E )‐ β ‐farnesene, or either ( E )‐ β ‐ocimene or ( E )‐ β ‐farnesene alone was as attractive as the TAS bait to male but not female G. molesta in Australia (Il'ichev et al. ). The first field study demonstrating a host plant volatile blend attractive to both sexes of G. molesta used six‐ and eight‐component blends derived from Chinese Pear Varieties (Lu et al.…”

Experiments were conducted in North and South America during 2012–2013 to evaluate the use of lure combinations of sex pheromones (PH), host plant volatiles (HPVs) and food baits in traps to capture the oriental fruit moth, Grapholita molesta (Busck), and codling moth, Cydia pomonella (L.), in pome and stone fruit orchards treated with sex pheromones. The combination of the sex pheromone of both species (PH combo lure) significantly increased G. molesta and marginally decreased C. pomonella captures as compared with captures of each species with either of their sex pheromones alone. The addition of a HPV combination lure [(E,Z)‐2,4‐ethyl decadienoate plus (E)‐β‐ocimene] or acetic acid used alone or together did not significantly increase the catch of either species in traps with the PH combo lure. The Ajar trap baited with terpinyl acetate and brown sugar (TAS bait) caught significantly more G. molesta than the delta trap baited with PH combo plus acetic acid in California during 2012. The addition of a PH combo lure to an Ajar trap significantly increased catches of G. molesta compared to the use of the TAS bait or PH combo lure alone in 2013. Female G. molesta were caught in TAS‐baited Ajar traps at similar levels with or without the use of additional lures. Ajar traps baited with the TAS bait alone or with (E)‐β‐ocimene and/or PH combo lures caught significantly fewer C. pomonella than delta traps with sex pheromone alone. Ajar traps with 6.4‐mm screened flaps caught similar numbers of total and female G. molesta as similarly baited open Ajar traps, and with a significant reduction in the catch of non‐targets. Broader testing of HPV and PH combo lures for G. molesta in either delta or screened or open Ajar traps is warranted.
