Grape moth trap /variegated/ REAGRON

Variegated vine moth (Lobesia botrana)

The variegated vine moth is a widespread, dangerous vine pest with three generations per year in Hungary. It overwinters under the bark of the vines in pupal form. It causes significant damage in vineyards together with the saddle grape moth.

Food plants

The main food plants of the variegated vine moth are grapes, but occasionally they can also be found on gooseberry and currant plantations.

Damage

Caterpillars of the first generation destroy the buds and berry beginnings of the bunches. The second generation prefers to chew on the ripening berries, and although their direct damage is small, the chewed berries open the way to botrytis rot.

Lifestyle

The variegated vine moth overwinters in pupa form. The swarming of the first generation begins at the end of April, the second from the end of June, and the third from the middle of August. Typically, the first and second draws are the most powerful. Female moths lay their eggs on the clusters, where the larvae hatch.

Defense advice

It is advisable to start protection with a long-lasting product after the first rash peak. By protecting with short-acting agents during the second swarm, the third swarm can remain weak, thus avoiding further sprayings.

Placing pheromone traps

The placing of pheromone traps from the middle of April helps to accurately determine swarms and protection times. Change the traps every 6-7 weeks and check them twice a week. With the help of the traps, swarming dynamics can be precisely monitored, which helps in effective protection against grape moths and gives the opportunity to protect the environment by minimizing spraying.
