No, bees die because of mono-cultures.
Since Capitalism cultivates only one type of bee, namely the common honey bee,
this one is much more likely to be attacked by pests, parasites, bacteria, fungus, viral diseases.
See here: https://en.wikipedia.org/wiki/List_of_diseases_of_the_honey_bee

Nature was smart enough to create multiple types of bees in order to be less vulnerable.
We diminished most of them.
Not everything is a conspiracy. Most problems are just pure stupidity/ideology
and lacking respect of nature. Nature is a system.
