Looks like you have no queen but laying workers. If you have access to brood give the hive a frame or two with bood in all stages. They might try to raise one on thier own. If you have laying workers they will try to kill any queen that you might try to introduce. A method that I recomend and use my self is the 2 inch square cage over the queen. Place the queen in this cage that is over sealed brood that is emerging, see http://www.glenn-apiaries.com/
for a picture on how to do this. I hope this helps you and good luck.
