How about rather than a conspiracy or plot etc, it is simply an infection which started with the Royal Jelly having unforseen consequences when ingested (maybe it didn't react well with the researcher's previous meal

) and now spreads much like a virus, requiring some specific form of contact or maybe that any victims have eaten the same foods as the researcher did (prior to ingesting the jelly) to be susceptible. That way
a) it becomesa task to find a cure
and
b) along the way the hive mind controller (maybe the tloke queen) could begin to become overwhelmed by all the new and different minds and starts to behave erratically/aggressively (giving the impression of conspiracy) or alternatively tries to seek help from other places in Yliakum ... the possibilities are almost endless.
There have probably been a number of conspiracy type themes played out already, maybe this slant would be a little different?
