Abstract

The aim of this paper was to identify European grapevine moths (Lobesia botrana Denis & Schiff.) flight dynamics, larvae occurrence and degree-day accumulations (DDA) for each moth generation in two Istrian vineyards with different pest management practices. The moth has developed three generations. During the third generation there was a significant flight peak in the vineyard without pest management. Predictions about larvae number and possible damage must be based on both, visual monitoring of grapevine and weekly adults catch. Developmental time with lower thermal threshold of 7 °C was calculated. The flight of the first generation was between 217.9 and 406.6 °C, second generation between 786.3 and 1329.8 °C, third generation between 1452.8 and 2108.2 °C.
