The vine is a commonly cultivated plant, both for the production of grapes to be consumed fresh and for the production of wine; this plant could be attacked by different types of parasitic insects, such as vine lepidoptera, which can cause more or less serious damage to crops. The damage done to plants can be of a different nature and be able to cause problems that are serious for crops. The parasites can cause lesions on the crown which prove to be able to reduce the photosynthesis capacity or they can directly ruin the bunches, reducing or canceling the production of the fruits. The main species that infest plants cause serious damage are, generally, the moth, the zigena, the buzzers and various types of mites. Being able to recognize the symptoms and the type of attack could be useful to save crops.
Tignolette are lepidoptera belonging to the Tortricide family whose larvae are able to attack the flowers and fruits causing damage. The damage that is caused by the moth can be extended as they grow and develop to the detriment of the bunches. The development of the moth is influenced by environmental factors, such as temperature, humidity and rain. Temperatures above 33 degrees block the growth of insects. For the fight against the insect, products containing Bacillus thuringensis could be used, because the toxin produced by the bacterium is able to act on the larvae. A further method of struggle could be sexual confusion, using specific pheromone traps, a disorientation could be induced in males which blocks them in fertilizing females.
