Field studies were conducted to evaluate new kairomone blends in combination with pear ester (E,Z)-2,4-ethyl decadienoate (PE) and acetic acid (AA) for their attraction of male and female codling moth, Cydia pomonella (L.), in apple, Malus domestica Borkhausen. The addition of decanal to either AA or PE alone significantly increased total and female moth catches. However, the addition of decanal did not improve the attraction of PE + AA. The addition of either the pyranoid (PyrLOX) or furanoid (FurLOX) linalool oxide but not linalool (LOL) increased moth catches with PE but did not increase catches with PE + AA. Similarly, the addition of PyrLOX plus decanal did not improve PE + AA. The addition of (E)-4,8-dimethyl-1,3,7-nonatriene (DMNT) to either AA, PE + AA or PE + AA+decanal did not significantly increase moth catches. However, the addition of PyrLOX to traps with PE + AA and DMNT (4-component lure) significantly increased moth catches compared with PE + AA alone or any of the ternary blends of these volatiles. Females accounted for 60%?80% of the total catch with this 4-component lure. The 4-component blend with PyrLOX was a more attractive lure than similar blends that substituted LOL, or a binary blend of LOL and FurLOX for PyrLOX. The 4-component blend caught nearly fourfold more total and female moths than the purported attractant N-butyl sulphide when it was used in combination with PE + AA. These results indicate that significant improvements in monitoring, mating disruption and mass trapping of codling moth are possible. Further studies are needed to assess the new attractive blend's effectiveness in combination with sex pheromone lures and to evaluate whether other host plant volatiles can be added or substitute for DMNT or LOX when used in combination with PE + AA.  © 2019 Blackwell Verlag GmbH  a(E)-4,8-dimethyl-1,3,7-nonatriene  a(E,Z)-2,4-ethyl decadienoate  aAcetic acid  aCydia pomonella (L.)  aIntegrated pest management  aLinalool oxide1 aMUJICA, V.1 aHERRERA, S.L.1 aTASIN, M.  tJournal of Applied Entomology, 2019, Volume 143, Issue 8, Pages 813-821.
