Laboratory insect husbandary/welfare

[keysi]

Hi guys, I'm writing a uni essay on whether insects should be afforded more welfare in research, and just struggling to find any sources on current conditions or practices, especially any that aren't politically motivated (not saying i'm for or against that, just not what i'm after). Can find plenty on edible insect welfare but not much, if anything, on insects in scientific research. If anyone knows any sources or where to look that would be much appreciated. Thanks in advance.
