Usually when booking flights no passport information is given but only name. Therefore it isn't a problem to use any passport on your name. My friend regularly uses two passports in the same trip - one to leave our country and another one to enter the destination country
You will not be able to enter Italy with your Filipino passport if you don't have a visa, however if you use your Irish passport for the flight then there is no need for a visa

In short, yes. I am a dual national of an EU and a non-EU country, and I routinely carry both passports, though I usually show only one or the other at any point in my trip.
You don't need a visa because you're an EU citizen. You should be able to make the trip entirely with your Irish passport. If you're worried about the airline because you've given them your Philippine passport number, then bring that along, too, and show it to them if they ask. But I doubt they will; mostly they just care that the name matches and that you're allowed to enter your destination.
When you cross the border, show your Irish passport to the border officers.

You will have to go through two separate checks of your documents, one before boarding and one after arrival.
For the second check, your Irish passport is all you need. For the first check, your Filipino passport may be necessary because that is what the airline's database says. The airline employees should accept the Irish passport instead of the visa. You can't board with just your Filipino passport and no visa, of course.
@phoog etc, as I understand it there is a Filipino passport without visa and an Irish passport, so she cannot use just the Filipino passport, but the airline expects to see the Filipino passport.
