IPM-CPR STRATEGY TO MANAGE HALYOMORPHA HALYS In order to cope with the rapid spread and high harmfulness of Halyomorpha halys in Emilia- Romagna Region, farmers have increased the use of broad-spectrum insecticides. This has often brought to give up the most innovative IPM strategies such as mating disruption (MD) or the use of microbiological products, with serious agro-environmental risks. Several investigations are underway in order to identify more sustainable control strategies against H. halys. Among these, IPM-CPR (Integrated Pest Management – Crop Perimeter Restructuring), is a particularly interesting strategy developed in the US, that utilizes border spray to intercept and eliminate H. halys in the orchard perimeter, where the pest is usually more abundant. In 2016-2017, field trials were performed to test this technique on pear orchards, with quite positive results. Adoption of IPM-CPR reduced insecticides usage by 44-50%. No significant differences were detected in the percentage of fruits damaged comparing IPM-CPR and standard treated orchards. Finally, this approach brings IPM strategies back into the orchards. To face the difficult management of this invasive pest, IPM-CPR seems to be a first useful operational proposal, and an easy-to-use technique, spreading in our areas.

Abstract
IPM-CPR STRATEGY TO MANAGE HALYOMORPHA HALYS In order to cope with the rapid spread and high harmfulness of Halyomorpha halys in Emilia- Romagna Region, farmers have increased the use of broad-spectrum insecticides. This has often brought to give up the most innovative IPM strategies such as mating disruption (MD) or the use of microbiological products, with serious agro-environmental risks. Several investigations are underway in order to identify more sustainable control strategies against H. halys. Among these, IPM-CPR (Integrated Pest Management – Crop Perimeter Restructuring), is a particularly interesting strategy developed in the US, that utilizes border spray to intercept and eliminate H. halys in the orchard perimeter, where the pest is usually more abundant. In 2016-2017, field trials were performed to test this technique on pear orchards, with quite positive results. Adoption of IPM-CPR reduced insecticides usage by 44-50%. No significant differences were detected in the percentage of fruits damaged comparing IPM-CPR and standard treated orchards. Finally, this approach brings IPM strategies back into the orchards. To face the difficult management of this invasive pest, IPM-CPR seems to be a first useful operational proposal, and an easy-to-use technique, spreading in our areas.
