Forum member @bspang kindly posted a link to his thesis, Insects as food: Assessing the food conversion efficiency of the mealworm, in the Insect FCR data? thread.
Brian, I hope you don't mind me reposting it here for everyone to see. There's a fantastic review of the current state of knowledge with regards to mealworm production (and insects-as-food in general), followed by the collection and analysis of feed conversion efficiency in a population of mealworms.
It's exciting to think we've only been around for a month, but we already have such great people in our community!
