Fungi also develop on the affected walnuts.<br>\nThe mature larvae crawl out of the husks to pupate in the soil.[\/vc_column_text][\/vc_column][\/vc_row][vc_row equal_height=&rdquo;yes&rdquo;][vc_column width=&rdquo;1\/3&Prime;][vc_custom_heading text=&rdquo;Where to find&rdquo; font_container=&rdquo;tag:h4|text_align:center|color:%23ffffff&rdquo; google_fonts=&rdquo;font_family:Lato%3A100%2C100italic%2C300%2C300italic%2Cregular%2Citalic%2C700%2C700italic%2C900%2C900italic|font_style:400%20regular%3A400%3Anormal&rdquo; css=&rdquo;.vc_custom_1537946500082{background-color: #536895 !important;}&rdquo;][vc_column_text el_id=&rdquo;entrytxt&rdquo; el_class=&rdquo;entrytxt&rdquo; css=&rdquo;.vc_custom_1703762283685{padding-left: 15px !important;}&rdquo;]<\/p>\n<ul>\n<li><a href=\"https:\/\/www.plantenplagen.nl\/en\/plantenplagen\/walnut\/\" target=\"_blank\" title='[vc_row][vc_column width=\"2\/3\"][vc_column_text el_id=\"topentry\" el_class=\"topentry\"]Walnut, supplier of the shorenut.
