Thanks Rader,
I read the linked thread about painting hives. I was hoping that the guy that Jredburn referenced had published his findings. I have not seen the data published. I took a run at finding out about this by emailing the entomology department UC Davis but did not find the correct person to respond to my request for additional information. It would be pretty nice if light in the hive and painting the wooden ware would control SHB....
