As a beekeeper, and one who does it for the bees rather than the honey (one kind of emotional motivation rather than another), there's a balance to be struck when using human emotions to describe bees (beyond the simplistic "don't anthropomorphize").
My friend worked for several years in undergrad on whether or not bees had individual personalities (this was her simplified description to me). So I asked her whether bees did have individual personalities, and her response was a flat "Nope".
The "emotions" that they're describing here are really more like states in a finite state machine. Calling them emotions obfuscates the science.
However, there might be a fun angle to building a brain out of increasingly complex emotional FSMs.
I blogged about it yesterday: http://blog.afandian.com/2016/09/first-honey/
