Ervedya heads a field of 14 to stand their ground in this year's French equivalent of the 1000 Guineas, the Poule d'Essai des Pouliches, at Longchamp on Sunday.
Placed in both the Prix Morny and Prix Marcel Boussac last year, the daughter of Siyouni made a winning reappearance in the Group Three Prix Imprudence last month.
She will attempt to give trainer Jean-Claude Rouget a second successive win in the mile showpiece following the victory of Avenir Certain 12 months ago.
The Frederic Rossi-trained Ameenah and Queen Bee, who hails from the yard of Elie Lellouche, will lock horns with Ervedya once again after finishing second and third respectively behind her in the Imprudence.
Criquette Head-Maarek saddles Fontanelice as she bids to win the race for a record eighth time, while Andre Fabre is to be represented by the unbeaten Mexican Gold and Soft Drink.
British runners are thin on the ground with the just two set to make the trip across the Channel.
Martyn Meade is to send over 1000 Guineas sixth Irish Rookie, while Jonathan Portman has left in last year's Cornwallis Stakes winner Royal Razalma.
The field is completed by Bilissie, Kenouska, Maimara, Penorka, Sainte Amarante and Qatar Dance.
