Previously, this species had been intercepted twice in 2012 through CDFA border stations and high risk pest exclusion inspections. A temporary rating of \u201cQ\u201d has been assigned. This pest rating proposal was prepared to determine a permanent pest rating.<\/p>\n<h5><strong>History &amp; Status:<\/strong><\/h5>\n<p><strong><u>Background<\/u><\/strong>: Thripini is the most phylogenetically diverse tribe in the family Thripidae, and <em>Thrips<\/em> is a highly evolved genus in subfamily Thripinae. <em>Thrips fuscipennis <\/em>is one of the commonly intercepted thrips in at U.S. ports of entry from Africa, Europe, and the Mediterranean. It is a polyphagous species characterized by the presence of ctenidia on abdominal tergites (4). The body length is 1.2-1.4mm, antennae are seven segmented and head is broader relative to most other thrips (5). Life stages consist of an egg, a first and a second larval stage, the propupal and pupal stage, and the adult stage. Reproduction is sexual or parthenogenetic. Eggs are laid in slits cut with the ovipositor into the host plant. Fertilized eggs produce females and unfertilized eggs produce males. One generation is completed in about one month. Thrips overwinter normally as a second stage larva or an adult female in bark crevices or plant debris (4). Hosts plants that <em>Thrips fuscipennis<\/em> can damage include roses, strawberries, bell pepper and white clover (3). Adult thrips are poor fliers but their feathery wings allow them to be readily carried by winds (6).<\/p>\n<p><strong><u>Worldwide Distribution<\/u><\/strong>: <em>Thrips fuscipennis <\/em>is native to England and present in Europe. It is currently distributed in <strong>Asia<\/strong>: China; \u00a0<strong>Europe<\/strong>: Albania, Austria, Czech Republic, Denmark, England, Estonia, Finland, France, Germany, Hungary, Ireland, Italy, Lithuania, Netherlands, Poland, Romania, Russia, Sardinia, Scotland, Serbia, Slovakia, Sweden, Switzerland, Trancaucasia, Turkey, Wales, and the former Yugoslavia. <strong>North America<\/strong> Canada (British Columbia, Quebec) (5).<\/p>\n<p><strong><span style=\"text-decoration: underline;\">US Distribution<\/span>: <\/strong>The first record of <em>Thrips fuscipennis<\/em> in North America was made by Hood based on his identification of a female collected in Ithaca, New York in July, 1926, on <em>Angelica atropurpurea. <\/em>This was later identified as <em>Thrips fallaciosus.<\/em> The first verified record of <em>Thrips fuscipennis<\/em> was reported from North America by Chaisson in 1986 in British Columbia. The various records of this species from Canada and the United States were misidentification of <em>Thrips<\/em> <em>fallaciosus<\/em>, which is widely distributed from Alaska and Labrador south to Utah, Colorado, Iowa, Illinois, and New York but has not been recorded from California to date(4).<\/p>\n<p><strong><u>Official Control<\/u><\/strong>: \u00a0<em>Thrips fuscipennis<\/em> is listed as harmful organism by Costa Rica, Japan, Republic of Korea and Taiwan (9).<\/p>\n<p><strong><u>California Distribution<\/u><\/strong>:\u00a0 <em>Thrips fuscipennis <\/em>has never been found in the environment of California.<\/p>\n<p><strong><u>California Interceptions<\/u><\/strong>: <em>Thrips fuscipennis<\/em> has been intercepted three times through CDFA\u2019s border stations and high risk pest exclusion programs (7).<\/p>\n<p>The risk <em>Thrips fuscipennis<\/em> (rose thrips) would pose to California is evaluated below.<\/p>\n<h5><strong>Consequences of Introduction:\u00a0 <\/strong><\/h5>\n<p><strong>1) Climate\/Host Interaction:<\/strong> <em>Thrips fuscipennis<\/em> is polyphagous and its hosts are grown throughout the state. This species can become established in areas of the state with warm spring and summers. Rain can wash thrips larvae from the hosts but if host plants are stressed due to drought, thrips infestations and populations can increase (4).

Common hosts include Roses (<em>Rosa<\/em>), Strawberry (<em>Fragaria<\/em>), bell pepper (<em>Capsicum annuum<\/em>) and white clover (<em>Trifolium repens<\/em>) and canola (<em>Brassica napus<\/em>\u00a0(3).

Each female lays about 100 eggs in its life time. Fertilized eggs produce females and males are produced from unfertilized eggs. One generation is completed in a month, but this can vary depending upon temperature. Adults are poor fliers but their feathery wings allow them to be readily carried by air currents (4, 6). Eggs concealed in plant tissue can easily be transported long distances when infested plants or cuttings are moved.

This was the main species encountered on plum and apple twigs in nurseries, mother apple plantations and in young orchards (2). This species can also cause fruit bronzing in strawberries resulting in lower fruit quality (1). If this species were to enter California, it would be likely to impact fruit crops and ornamental plantings. Since <em>Thrips fuscipennis<\/em> is commonly intercepted at US ports of entry, this species is likely to trigger quarantine for California commodities.
