Several kinds of wireworms are in the Pacific Northwest. Wireworms causing the most damage in irrigated areas are the Pacific Coast wireworm (<em>Limonius canus<\/em>), the sugar beet wireworm (<em>L. californicus<\/em>), the western field wireworm (<em>L. infuscatus<\/em>), and the Columbia Basin wireworm (<em>L. subauratus<\/em>). The Pacific Coast and sugar beet wireworms are the most common. Where annual rainfall is &lt;15 inches, the Great Basin wireworm (<em>Ctenicera pruinina<\/em>) may be a problem, especially when irrigated crops are grown on sagebrush or dry wheat land. This species usually disappears after a few years of irrigation, but may be replaced by <em>Limonius spp<\/em>. which are favored by moist conditions. West of the Cascades, other wireworm species are pests, including&nbsp;<em>Agriotes&nbsp;spp<\/em>.<br><b>Host crops<\/b>: All crops are susceptible to wireworm, but this pest is most destructive on <br>beans,&nbsp;<a href=\"https:\/\/mtvernon.wsu.edu\/path_team\/photo-gallery-of-vegetable-problems\/carrot\/#Wireworm\">carrot<\/a>, corn, grain,&nbsp;<a href=\"https:\/\/mtvernon.wsu.edu\/path_team\/photo-gallery-of-vegetable-problems\/onion-allium\/#Wireworm\">onion<\/a>,&nbsp;<a href=\"https:\/\/mtvernon.wsu.edu\/path_team\/photo-gallery-of-vegetable-problems\/potato\/#Wireworm\">potatoes<\/a>,&nbsp;<a href=\"https:\/\/mtvernon.wsu.edu\/path_team\/photo-gallery-of-vegetable-problems\/spinach\/#Wireworm\">spinach seed crops<\/a>, and other annual crops in the PNW.<\/p>\n\n\n<div class=\"wsu-row wsu-row--quarters\" >\r\n    \n<div class=\"wsu-column\"  style=\"\">\r\n\t\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/mtvernon.wsu.edu\/path_team\/potato-wireworm1l\/\"><img decoding=\"async\" loading=\"lazy\" width=\"467\" height=\"384\" src=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/potato-wireworm1L.jpg\" alt=\"wireworm adult\" class=\"wp-image-567\" srcset=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/potato-wireworm1L.jpg 467w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/potato-wireworm1L-396x326.jpg 396w\" sizes=\"(max-width: 467px) 100vw, 467px\" \/><\/a><figcaption class=\"wp-element-caption\">Adult wireworm is commonly known as a click beetle.
