European grapevine moth overwinters as a pupa, constructing cocoons in the bark of grapevines or in soil cracks. First-generation adults emerge from pupation when temperatures become warm, usually in the middle of spring.

Identifying European Grapevine Moth. There are many types of tortricids that can be confused for European grapevine moth and other moths. Adult moths must be identified by a qualified entomologist. Larval stages cannot be reliably identified using morphological characters.

The European grapevine moth (EGVM) Lobesia botrana (Denis & Schi ermüller) (Lepidoptera: T ortricidae) is among the most economically important pests in European

The European grape berry moth (EGBM), E. ambiguella, is considered a significant insect pest in many grapevine-growing areas where it can cause considerable damage to grapes. It is found from Britain to Japan, from the Mediterranean Basin to the Scandinavian countries (farther north than grapevine-growing regions) (CAB 1986 ).

The purpose of this study was to determine the effect of host plant characteristics on the rate of larval growth and the pattern of emergence in a wild population of Lobesia botrana (European grapevine moth), a significant pest in European vineyards.
