The Poplar shoot-borer (''Gypsonoma aceriana'') is a moth of the Tortricidae family. It is found from Europe to Russia, eastern Turkey and Iraq. It is also present in North Africa. The wingspan is 13–15 mm. Adults are on wing in July. In Japan, there are two to three generations per year (in June, July and August). The larvae feed on ''Populus nigra'', ''Populus nigra subsp. italica'', ''Populus alba'', ''Populus balsamifera'', ''Acer platanoides'' and ''Acer campestre''. It is a common species in poplar plantations and nurseries. It has been recorded as a pest from Italy, France, Germany and the Netherlands. Older larvae (third instars) bore into buds and below terminal shoots, which are usually destroyed, causing bushy growth of lateral shoots and making young trees unmarketable. ==References==
