Temperature and daylight length do have an effect on how many drones they raise but the amount of fresh nectar coming in seems to have a greater effect. As long as they are getting some fresh honey a lot of hives will still keep raising drones and I have seen my hives around home with drone brood in them all winter. I would be more concerned about how late you are putting your strips in. You are not leaving much time to raise healthy varoa free bees before winter.
