Abstract

The article discusses the phenological features of the elm leaf beetle Galerucella luteola Mül. based on two-year (2018–2019) research in the stands of Kharkiv and in a laboratory environment. Depending on weather conditions, 2–3 generations of elm leaf beetle per year may develop in Kharkiv. Beetles hibernate in bark crevices, hollows or in a litter. They leave the wintering places during elm leaves blooming (in late April – early May). The egg-laying period is extended, generations overlap. Development of eggs lasts 6–10 days, larvae develop 18–29 days, pupae about 10 days. Phenological calendar for elm leaf beetle is compiled as the result of the research.
