Plotting an aov object is done by stats:::plot.lm.  From the help page 
?plot.lm, I think the value that you want to change is the "caption" 
argument, i.e.


  plot(my_aov, which=1, ann=FALSE,
        caption = "Résidus vs Valeurs prédites")
  title(xlab="Valeurs prédites", ylab="Résidus", main="Mon titre")

You can use `caption = NA` to suppress it.
