The aim of the work was to determine the influence of recent climate changes on geographical distribution of the pest Tanymecus dilaticollis Gyll. in the main maize and sunflower growing areas from south and southeastern Romania. In the period 2021-2022, monitoring of the adults activity in laboratory and field conditions, adults abundance and climatic parameters were carried out in 60 farms. The results showed that the increase in temperature favour the activity of Tanymecus dilaticollis, the adult active period longevity was found to expanded by approximately 20%. The pest adult’s abundance during the maize and sunflower early vegetation period varied from 3.67 to 27.24 adults per square meters in 2021 and from 7.21 to 16.27 adults per square meters in 2022.
