Nope, no fruits - in fact, AIWarrush actively FORBIDS its workers from taking fruit! Fruit wouldn't be powerful enough to do that anyway - you can only convert as many units as you have inns, and there isn't enough room to build that many inns without defeating some enemies in the first place. Warrush just expanded and built; at the end, it had ten swarms, 150+ workers, and 100+ warriors.
(You have to remember that that chart is hours long and much taller than a normal chart. It looks like fruits but it's at the wrong scale.)
Against Nicowar, it beats one easily on Muka; it usually beats two Nicowars on Easy Three. However, if it has to break through two enemies before getting to a Nicowar, it's too late and the fruits conquer it.
In other news, Warrush is now back in CVS, although there's a strange bug - if you play against a Warrush, the game displays its areas rather than your own, although the effects are still correct...
