The Lily Thrips (Liothrips vaneeckei, Priesner)

“…These writers further suggested that it was known also in England and Belgium and were of the opinion that it might be indigenous to Oregon, U.S.A., where it occurs in abundance upon a native lily, L. washingtonianum. Also in 1932 van Poeteren 4 recorded the thrips in bulbs of L. martagon imported into Holland from Italy. The first authentic record in England, referred to above, was in November 1933, but information furnished by commercial growers rather suggests that it may have been sporadically present in the country for approximately the past ten years.…”
