European Grapevine Moth
The main host is the vine. Laurel, forest vine, jujube, blackberry
Adults have a wingspan of 10-12 mm and a length of up to 6 mm. Mature larvae are 9-10 mm long, yellowish green in color. Females lay their eggs on flower buds, flowers and flower stalks, unripe grape and fruits. The newly hatched larva feeds on buds and flowers. The second progeny larva feeds on the unripe grape, the third progeny larva feeds on the ripening grapes. They usually give 3 offspring.
Type of Damage
The grapevine moth is the most important pest of vineyards with the damage it causes directly on the product. There is loss of quality and quantity in the product during their feeding. Damaged flowers and groves fall. The inflorescences become sparse. Saprophytic fungi develop in the inflorescences.
Traps are hung as 1 piece/ha before the flowering period and after the temperature reaches 12 degrees. Traps are counted once every 2 weeks until the first insect is seen, and once a week after the first insect is seen. When adult flight is detected, appropriate control is carried out.
They are placed in the vineyard at 15-20 m intervals; delta traps, funnel traps, water traps etc. Thus, fertilization of female eggs is prevented. A fairly high success is achieved.
