Tortrix viridana (Linnaeus, 1758) (Lepidoptera: Tortricidae) (TV) is a serious pest of oaks in the West-Palearctic. In Ukraine in the 50–70s of the 20th century, the area of TV outbreaks reached 140–180 thousand hectares. Since the late 1980s, outbreaks have become rarer and [...] Read more.
Tortrix viridana (Linnaeus, 1758) (Lepidoptera: Tortricidae) (TV) is a serious pest of oaks in the West-Palearctic. In Ukraine in the 50–70s of the 20th century, the area of TV outbreaks reached 140–180 thousand hectares. Since the late 1980s, outbreaks have become rarer and have occurred in a smaller area. This research aimed to assess the main parameters of TV outbreaks in Ukraine, considering its prevalence in flush feeders’ complex, the suitability of forest structure for this insect, and the phenological mismatch between bud-flushing and TV hatching. Historical data on TV outbreaks in Ukraine since 1947, data for 1978–2025 by regions, field and climate data, and forest management databases as of 1996 and 2017 from the Kharkiv region were analyzed. Since 1985, the incidence, severity, and duration of TV outbreaks have decreased in all regions of Ukraine. It was explained by: (1) TV decrease in the flush feeding complex due to monophagy; (2) decrease in the suitable area due to a change in the forest age composition, proportion of pure oak stands, and stands with low relative stocking density; (3) the shift of oak bud-flushing and TV hatching to earlier dates with the tendency of earlier bud-flushing than egg-hatching.
