The American leafhopper Erasmoneura vulnerata, detected in Europe in the early 2000s, has recently become a pest in North-Italian vineyards. Infestations were recorded in organic and conventional vineyards despite the application of insecticides targeting other pests. Erasmoneura vulnerata completes three generations per year, and the second generation is frequently associated with large populations. The selection of appropriate active ingredients and the timing of their application is crucial for effective pest control. Field trials were carried out in Northeastern Italy, using a randomized design, to evaluate the impact of insecticides applied against other grapevine leafhoppers on E. vulnerata populations. The beginning of the second generation was selected as the best time for insecticide application. For natural products, two applications were planned. Among the selected insecticides, the most effective were acetamiprid, flupyradifurone and lambda-cyhalothrin. Regarding natural products, the most effective was kaolin which could represent an alternative to pyrethrins in organic vineyards. The identification of pest threshold levels and the evaluation of side effects of the most effective insecticides on key natural enemies occurring in vineyards are required.

在欧洲葡萄园中对美国叶蝉草（Erasmoneura vulnerata（Fitch）的控制：合成杀虫剂和天然杀虫剂的影响

在2000年代初期在欧洲发现的美国蝉叶蝉（Erasmoneura vulnerata）最近已成为北意大利葡萄园的害虫。尽管使用了针对其他害虫的杀虫剂，但在有机和常规葡萄园中仍记录了侵扰。毛ras每年完成三代，而第二代通常与人口众多有关。选择合适的活性成分及其施用时间对于有效控制害虫至关重要。使用随机设计在意大利东北部进行了田间试验，以评估杀虫剂对其他葡萄叶蝉的施用对E. vulnerata的影响人口。第二代开始被选为施用杀虫剂的最佳时间。对于天然产品，计划了两个应用程序。在选定的杀虫剂中，最有效的是乙酰胺，氟吡呋酮和λ-氯氟氰菊酯。关于天然产品，最有效的是高岭土，它可以替代有机葡萄园中除虫菊酯的替代品。需要确定有害生物的阈值水平，并评估最有效的杀虫剂对葡萄园中主要自然敌人的副作用。
