You can check whether a given actor is in a world using 
boolean isInAWorld = actor.getWorld() != null;

Use act method in world and check if list of objects in world of that type is empty. Sample code follows (see line 3): 
public void act()
{
    if (getObjects(Bat.class).isEmpty())
    {
        setText("GAME OVER", 300, 200);
        Greenfoot.stop();
    }
}
