Resumen:

ABSTRACT.Seventeen trials were conducted using traps baited with kairomone-based lures to evaluate female removal (FR) as an effective management tactic for codling moth, Cydia pomonella, L., in organic pear, Pyrus communis L., production in Italy and USA during 2019?2020. Studies included paired plots (0.4?1.4 ha) treated with or without 60 traps ha?1 in cultivars Bartlett and Abate Fétel. Paired plots were also treated together with or without mating disruption (MD) and with similar spray programmes. Three-, four-, and five-component lures were used with several trap types: green, clear or green/white bucket traps and orange delta traps. The three-component lure consisted of (E,E)-8,10-dodecadien-1-ol (sex pheromone, PH), (E,Z)-2,4-ethyl decadienoate (pear ester, PE) and acetic acid (AA); the four-component lure was PE, (E)-4,8-dimethyl-1,3,7-nonatriene (DMNT), 6-ethenyl-2,2,6-trimethyloxan-3-ol (pyranoid linalool oxide, LOX), and AA, and the five-component lure had PH added. Preliminary studies were also conducted to evaluate the trapping efficacy of non-saturating bucket traps. A clear bucket trap baited with PE/DMNT/LOX + AA captured 97-fold more codling moth females than an orange delta trap baited with PH/PE. However, female captures did not differ between traps when both were baited with the four-component lure. Fruit injury from codling moth was significantly reduced with the implementation of FR in both pear production regions. At harvest, mean fruit protection in the USA studies was 65% and 27% in Italy. This difference was likely associated with the four-component lure being less effective in Italy than in the USA. Nevertheless, results demonstrate that FR can be a useful approach to remove females immigrating into orchards and as a new tactic to reduce pest pressure in selected areas of orchards allowing both MD and organic insecticide programmes to be more effective. Further studies should investigate the cost-benefit of matching the intensity of FR to variable pest pressures. © 2021 The Authors. Journal of Applied Entomology published by Wiley-VCH GmbH.
