The introduction of the Japanese beetle (Popillia japonica Newman) in Italy raised concerns for its control in herbaceous and perennial crops, nurseries and landscape plants. During the early stages of spread of an invasive pest, the availability of effective insecticides is essential to sustain the immediate needs of plant protection. Here, we screened the effects of 20 active ingredients representative of chemical and organic insecticides registered in Europe for adult beetle management on high-value crops (grapevine, peach and corn) and landscape plants (willow and Virginia creeper) by field trials carried out in 2019 and 2020. Plant parts suitable for spraying were sleeved and beetles were caged before the application (contact effect), after the application but on the same day (residual, short-term effect), and 7–8 days after the application (residual, long-term effect). Among the 20 active ingredients tested, only four broad-spectrum (acetamiprid, deltamethrin, lambda-cyhalothrin and phosmet) were effective in killing beetles under all the experimental conditions, while other broad-spectrum and selective ingredients were mainly effective only on contact and as short-term residual. The organic active ingredients were much less effective under any condition. The data provide a valid support to update the European guidelines aimed at controlling P. japonica for growers, landscape managers and homeowners. The low selectivity of the most effective insecticides requires the integration into management strategies that envisage their use only whether strictly necessary, and in combination with other containment measures.

意大利北部高价值作物和园林植物白杨成虫的化学防治

日本甲虫(Popillia japonica )的引种Newman)在意大利引起了对其在草本和多年生作物、苗圃和园林植物中的控制的担忧。在入侵性害虫传播的早期阶段,有效杀虫剂的可用性对于维持植物保护的紧迫需求至关重要。在这里,我们通过田间试验筛选了 20 种代表在欧洲注册的用于管理成虫的化学和有机杀虫剂对高价值作物(葡萄、桃和玉米)和景观植物(柳树和弗吉尼亚爬行物)的影响。 2019 年和 2020 年。 施药前(接触效应)、施药后但同一天(残留、短期效应)和施药后 7-8 天(残留效应)对适合喷洒的植物部位进行套套和甲虫笼养。 ,长期影响)。在测试的 20 种活性成分中,只有四种广谱(啶虫脒、溴氰菊酯、λ-三氯氟氰菊酯和亚磷酰胺)在所有实验条件下均能有效杀死甲虫,而其他广谱和选择性成分主要仅在接触时有效,作为短期剩余。有机活性成分在任何条件下都不太有效。数据为更新旨在控制的欧洲指南提供了有效支持P. japonica适合种植者、景观管理者和房主。最有效杀虫剂的低选择性要求纳入管理策略,仅在绝对必要时才使用它们,并与其他遏制措施相结合。
