Ireland trounced Italy 39-0 at the Aviva Stadium on Saturday to keep alive their chances of retaining the Women's Six Nations Championship.
Full-back Niamh Briggs landed two penalties before flanker Claire Molloy scored the opening try for a 13-0 lead.
Lynne Cantwell's try just before half-time gave Philip Doyle's side a 20-point advantage.
Alison Miller, Heather O'Brien and Jenny Murphy added tries for the dominant hosts in the second half.
It leaves the Irish with three wins from four matches and they head the table on goal difference.
However, 100% France will go two points clear at the top if they beat Scotland on Sunday.
