A survey in Hungary found that 93% of respondents have seen significant damage to walnut plantations from the western walnut borehole pest, with 25% giving up on the crop and considering cutting down the trees. Despite this, the largest walnut plantations are not at risk with the proper application of costly chemical control. Hungary's nut-growing area has expanded from 3,000 to over 7,000 hectares in the last ten years, with an annual yield of 7,000 tons and a production value of HUF 4-6 billion. The pest, originally from the United States and Mexico, has been in Hungary since 2011.
