Helicoverpa armigera is a polyphagous and globally distributed pest. In Italy, this species causes severe damage on processing tomato. We compared the efficacy of mating disruption with a standard integrated pest management strategy (IPM) in a two-year experiment carried out in Northern Italy. Mating disruption registered a very high suppression of male captures (>95%) in both growing seasons. Geostatistical analysis of trap catches was shown to be a useful tool to estimate the efficacy of the technique through representation of the spatial pattern of captures. Lower fruit damage was recorded in mating disruption than in the untreated control plots, with a variable efficacy depending on season and sampling date. Mating disruption showed a higher efficacy than standard IPM in controlling H. armigera infestation in the second season experiment. Mating disruption showed the potential to optimize the H. armigera control. Geostatistical maps were suitable to draw the pheromone drift out of the pheromone-treated area in order to evaluate the efficacy of the technique and to detect the weak points in a pheromone treated field. Mating disruption and standard IPM against H. armigera were demonstrated to be only partially effective in comparison with the untreated plots because both strategies were not able to fully avoid fruit damage.

在加工番茄上对棉铃虫（鳞翅目：夜蛾科）的交配破坏：在意大利北部的首次应用。

棉铃虫是一种多食性和全球分布的害虫。在意大利，这种物种对加工番茄造成严重损害。在意大利北部进行的为期两年的实验中，我们将交配破坏的功效与标准的病虫害综合治理策略（IPM）进行了比较。在两个生长季节中，交配破坏对雄性捕获的抑制作用都非常高（> 95％）。圈套捕获物的地统计分析被证明是通过表示捕获物空间模式来评估该技术效力的有用工具。与未处理的对照地块相比，在交配处记录到的果实损害更低，其功效随季节和采样日期而变化。交配破坏在控制棉铃虫中显示出比标准IPM更高的功效在第二季实验中感染。交配破坏显示了优化棉铃虫控制的潜力。地统计学图适合于将信息素漂移移出信息素处理过的区域，以评估该技术的功效并检测信息素处理过的领域中的薄弱点。与未经处理的地块相比，交配破坏和针对棉铃虫的标准IPM仅被证明部分有效，因为这两种策略均无法完全避免水果受损。
