Olivo-damaging insects: moth olive (Prays oleae)

The olive moth, a butterfly's wing about 13-15 mm of Operation data, white heron, which has mainly three generations of annual growth, including:
1. Larva of 1st generation
2. Larva 2nd generation;
3. Larva of the 3rd generation
All three generations, respectively attack leaves, flowers and fruits. The larvae mature
are about 8mm long and have a color ranging from green to reddish-brown heron with his head. The first generation
penetrates the flower buds destroying the various reproductive organs, but the 2nd generation larvae, which are the most dangerous attack fruitlets digging up all galleries' endocarp, and also causing the premature fruit drop of the fruit itself, and finally the 3rd generation, where burrow winding tunnels in the leaves, making them dry from the outside, this type of larvae may also enter into the buds, causing the seccume on these. The fight is kind of chemistry and agronomy: the chemicals used are all based on phosphorus, and interventions are carried out mainly larvae in the 2nd generation because other generations do not involve serious damage to ripening, the interventions are made during June and July at the end of the first oviposition and larval penetration of the small fruits. Instead, as regards agricultural techniques are used insects, including, entomophagous predators (Rincoti anthocorid, Diptera and Neuroptera Sylphs Crisopidi) and parasitoids (Hymenoptera Calcidoidei Braconidi and Hymenoptera).
