There was a thread posted on arachnoboards recently attributing massive increases in producation to using oranges or grapefruit in some cases.  I personally didn't have any dubia reproducing for months until I added oranges and alot of people have had the experience.  Has anybody run into something similar?  Is that a documented thing or mass coincidence?  Maybe we all on arachnoboards are feeding our roaches nutrient sufficient food, supplemented by oranges?
