Studies were conducted during the period 2019/2020 to evaluate the effectiveness of four lures for codling moth ( L.) in pome fruits in Italy and the USA. Multi-component blends of sex pheromone ((,)-8,10-dodecadien-1-ol, PH), pear ester (()-2,4-ethyl decadienoate, PE), ()-4,8-dimethyl-1,3,7-nonatriene (DMNT), and pyranoid linalool oxide (6-ethenyl-2,2,6-trimethyloxan-3-ol, LOX) were loaded in either a halobutyl elastomer septum or a PVC matrix and always used in combination with acetic acid (AA) loaded in a closed membrane co-lure. Total moth capture was significantly greater with the PVC than the septum lure loaded with PH/PE + AA in both countries. Female capture in the USA study was significantly greater for 8 weeks in traps baited with the PE/DMNT/LOX blend + AA co-lure than with other lures and adding PH to this blend in a PVC lure significantly reduced female capture. In contrast, female capture in Italy did not differ among lures and counts were similar in both apple and pear crops treated with or without mating disruption. These results suggest that the effectiveness of 'female removal' strategies to manage codling moth may be geographically limited and further comparisons are needed in other production regions and in walnut.
在2019年至2020年期间开展了多项研究，以评估四种诱捕剂对意大利和美国梨果中苹果蠹蛾（Cydia pomonella (L.)）的诱捕效果。性信息素（(Z,E)-8,10-十二碳二烯-1-醇，PH）、梨酯（(E,E)-2,4-癸二烯酸乙酯，PE）、(E)-4,8-二甲基-1,3,7-壬三烯（DMNT）和吡喃型氧化芳樟醇（6-乙烯基-2,2,6-三甲基氧杂环庚烷-3-醇，LOX）的多组分混合物被载入卤丁基弹性体隔片或聚氯乙烯（PVC）基质中，并始终与载入封闭膜协同诱捕器中的乙酸（AA）联合使用。在这两个国家，装载PH/PE + AA的PVC诱捕器捕获的蛾类总数均显著多于隔片诱捕器。在美国的研究中，用PE/DMNT/LOX混合物 + AA协同诱捕器诱捕的诱捕器中，雌性捕获量在8周内显著高于其他诱捕器，并且在PVC诱捕器中向该混合物中添加PH会显著降低雌性捕获量。相比之下，在意大利，不同诱捕器捕获的雌性数量没有差异，在进行或未进行交配干扰处理的苹果和梨作物中捕获数量相似。这些结果表明，“去除雌性”策略管理苹果蠹蛾的效果可能存在地理局限性，需要在其他生产地区和核桃上进行进一步比较。
