(Spencer, 1973).\u00a0 This fly is a pest in field crops and in greenhouses.\u00a0 An unusually broad range (for an agromyzid) of plant families are attacked, including Apiaceae, Asteraceae, Brassicaceae, Capparaceae, Caryophyllaceae, Chenopodaceae, Cucurbitaceae, Fabaceae, Malvaceae, and Solanaceae, among others (Spencer, 1990).\u00a0 Economically-significant host plants include tomato, cucumber, melons, beans, parsley, coriander, lettuce, squash, spinach, peppers, petunias, and chrysanthemum (Elkhouly et al., 2015; Masetti et al., 2004; Minkenberg and Van Lenteren, 1986; Shiao, 2004; Tran, 2009; Van Der Linden, 1993). \u00a0Reproductive potential is high.\u00a0 Individual females have been reported to lay up to 183 eggs (Tokumaru and Abe, 2003). The eggs are laid in leaves that then serve as food for the larvae.\u00a0 \u00a0The larvae are legless and cream to yellow-orange in color, and tunnel or \u201cmine\u201d between the upper and lower epidermal layers of the leaf. The mines are not associated with the leaf veins (as in some other agromyzid species), except sometimes the midrib, and sometimes form secondary blotch mines.\u00a0 The larvae exit the leaf to pupate, presumably in soil like most <em>Liriomyza<\/em> species (Collins and Anderson, 2016; Pitkin et al., 2017; Spencer, 1973).\u00a0 Larval feeding damage can kill the leaves and sometimes the entire plant, especially if it is young (Spencer, 1973).\u00a0 Some <em>Liriomyza<\/em> species are known to vector plant viruses, although it is not known if <em>L. bryoniae<\/em> does (Zitter and Tsai, 2013), and some agromyzids are known to vector plant pathogenic fungi (Mathew et al., 2015).<\/p>\n<p><strong><u>Worldwide Distribution<\/u><\/strong><strong><u>:<\/u><\/strong>\u00a0 <em>Liriomyza bryoniae<\/em> is widely distributed and present from Europe and northern Africa east to East Asia.\u00a0 It is apparently native to southern Europe; the other areas it is found in (including northern Europe, where it is found mainly in greenhouses) are presumed to represent introductions (CABI, 2018; Minkenberg and Van Lenteren, 1986; Spencer, 1973).<\/p>\n<p><strong><u>Official Control:<\/u><\/strong> <em>Liriomyza bryoniae<\/em> is listed as a high priority pest in Australia and it is considered Reportable by the USDA-APHIS.<\/p>\n<p><strong><u>California Distribution: <\/u><\/strong>\u00a0<em>Liriomyza bryoniae<\/em> is not known to be present in California (Symbiota Collections of Arthropods Network).<\/p>\n<p><strong><u>California Interceptions:<\/u><\/strong>\u00a0 <em>Liriomyza bryoniae<\/em> may have been intercepted on <em>Polemonium<\/em> sp. from Washington in September, 2002.\u00a0 This identification was tentative (California Department of Food and Agriculture).<\/p>\n<p>The risk <em>Liriomyza bryoniae <\/em>w<em>o<\/em>uld pose to California is evaluated below.<\/p>\n<h5><strong>Consequences of Introduction:<\/strong><\/h5>\n<p><strong>1) Climate\/Host Interaction:<\/strong> <em>Liriomyza bryoniae<\/em> is widely distributed, suggesting it is tolerant of a wide range of conditions.
