The Control of the American Leafhopper Erasmoneura vulnerata (Fitch) in European Vineyards: Impact of Synthetic and Natural Insecticides

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