Gypsonoma minutana

Poplar tortricid

Description

Gypsonoma minutana, commonly known as the poplar tortricid, is a moth belonging to the family Tortricidae. This species is distributed across Europe, extending northward to Finland, and is also found in North Africa, Turkey, Transcaucasia, the Ural region, Kazakhstan, central Asia, Siberia, eastern Russia, Asia Minor, Iran, Afghanistan, Mongolia, China, and Japan. The adult moth has a wingspan ranging from 12 to 15 mm and is typically active in July in England. In Japan, there are two to three generations annually, with adults appearing in June, July, and August. Similarly, in Italy, two to three generations occur per year, with flight periods from late May to mid-June, late July to mid-August, and mid-September to late October. The larvae primarily feed on poplar species, including Populus nigra, Populus alba, and Populus tremula. They spin two leaves together during May or June, creating a sheltered feeding site. While the feeding activity of the larvae can cause some damage to the foliage, the intensity of infestation is usually not severe enough to significantly impact the overall health or aesthetic appearance of the host trees.

Symptom

Infested leaves are bound together with silk, forming a protective enclosure where the larvae feed. This results in minor defoliation and the presence of spun leaves.
