Adult pest insect has about 12 mm, wigspan is of 10 – 12, 5 mm. Male is smaller in size than European Grapevine Moth female. Lobesia Botrana has two pair of wings, first are of light cream color with blotches of different colores, second pair of wings are of gray color with a fringed border.
Lobesia botrana might complete from 3 to 5 generations, depending on climate of state where it lives. First generation is the largest. Lifespan of pest insect is short, about 3 weeks.
Lobesia botrana female can lay about 35 eggs a day. Egg development depends on climate conditions, usually it might take 3-10 days.
First two generations pupate in twisted leaves or flowers tied with silk. Next generations pupate in soil and emerge the following spring.
Grown larvae have about 10-15 mm long of light yellowish green till pale brown color. Larvae head is brown to yellow honey color, antennae and feed are brown.
Larvae lives in bunches, webs around flower parts weaving them together and feeds; larvae may enter the peduncle and cause dry up of the grape bunch. When disturbed pest insect wiggles and drops down on silken thread.
European Grapevine Moth damages grapes and berry fruits; larvae pupate and are feeding in berries and not only these.
Lobesia botrana larvae damages plants in the following way: first generation attacks inflorescence, the rest generations perforates the green berries and feeds on the interior content remain only skin and seeds, the most dangerous is when it feeds inside berries and bunches, and contaminating them with excrements.
Lobesia botrana pheromone traps will prevent pest insect damage to your crops.
Main way of grapevine moth dispersion is with exported infested fruits. This pest insect very well adapts to new climate conditions, this is why it spread very easy through all Europe.
Adult insect do not disperse because they do not fly to long distances, only at short about 80 meters maximum.
Pest insect dispersion and protection of crops can be controlled if you use pheromone traps and place them accordingly to their prescription.
Pheromone traps have to be placed about two weeks before bud break from consideration 1 trap for every 30 acres and 2 pheromone traps for vineyard. These traps can be used to detect the first, second and third generation emergence of the grapevine moth adults. Pheromone traps will help to confuse grapevine moth males and will lead to protection of your grapevine crop.
Pheromone traps are more effective than the use of insecticides, because the third generation is within grape bunches and can’t be reached by. This is the reason why most effective are trapes with pheromones that should be placed before even first generation appeares.
