I guess C (if you meant "observing") is a tempting choice to go with, but the idea is that entomologists use insects as a barometer of the ecosystem. So what concerns entomologists is what insect communities reveal about the environment, rather than about the insect population itself. Hence, what an entymologist needs to keep track of is insects' interactions with their environment, i.e. their conditions in the environment. Also, "register" here means "to make a record of something."
