Only about a dozen papers treat BC that come up in Google Scholar. I am unable to find original source I had for interspecies comparison of feed activity as that may have been a personal communication. My efforts with BC, CC and F1 hybrid CC(female) X BC(male) were back in the 1990's, so not fresh. Yet, I am confident about relative feeding activities as a function of temperature as we had several ponds running in parallel giving similar pattern.
