Could it be a reason why queens don't last nearly as long as they used to, having run out of sperm?

> There was a thread here just a while back somewhat related to this issue and in regards to published research using some of my own bees.  The entire thread should suggest to you that 'season' and quality of nutrition can be at least a significant portion of the problem.  As I also suggested it does take a bit of practice to capture sexually mature drones.. < another contributor seems to suggest about 2 weeks for a drone to get to sexual maturity but as this project rolled along we got to thinking that sexual maturity in drones may take a bit longer than the 2 weeks suggested in books.
