Marley Watkins headed James Maddison's 14th minute free kick onto the outside of the post before Wolves struck, Boly heading home Barry Douglas's corner at the near post.
Bonatini was not far away from a second from an acute angle minutes later but both defences were on hand with timely blocks from any shooting opportunities for the remainder of the half.
Wolves made a strong start to the second half but were unable to capitalise on their chances until the 72nd minute when Ryan Bennett's flick set up Bonatini to fire home his ninth goal of the season to clinch a comfortable win.
