The 20-year-old, who returned to Bloomfield Road after playing a part in their march to the npower Championship play-off final last term, scored five goals in 22 games for the Seasiders this season.
All but two of those appearances came as a substitute and Pool boss Michael Appleton revealed Latics were unhappy at the amount of game time on offer to the French youngster.
"They've recalled him obviously because of his lack of first-team minutes, which we've got to respect," Appleton told Blackpool's official website.
Dicko's fellow forward Wes Thomas has returned to Bournemouth following the end of his own loan spell.
Thomas is Appleton's only signing for Blackpool to date and he scored three goals in nine matches.
Elsewhere, veteran midfielder Barry Ferguson and 20-year-old forward Tom Barkhuizen are back at Bloomfield Road loan spells with neighbours Fleetwood.
