Bee Tangent: Ngram?

My husband just saw mention of Google Ngrams onTWIT  TV's  This Week in Google and sent me the link.  

What Ngram does is see how many times a phrase (or other stuff if you want) appears in publications in a  span of years.

So how many times does the phrase honey bee appear over the years, what percent of all scanned publications does it appear in?  

  1976?  So, what was all the honey bee buzz in 1976?
 
                     Look below the graph to see what I found.

• In 1976, the US Department of Agriculture published a report by one of its former employees, S. E. McGregor, a honeybee expert who documented that about a third of what we eat benefits from honeybee pollination. This includes vegetables, oilseeds and domesticated animals eating bee-pollinated hay.

•  In 1975 and 1976, Varroa disease was found in Argentina and Uruguay. There is a possibility of this disease to also exist in the northern region of Africa. (It was in Bulgaria in 1964.) 

I couldn't find anything much of general public interest.   Tons of normal scientific research though.  I'm thinking it must be the result of the last 10 years of funding for research which became available due to increased awareness of what was at stake when the varroa mite made its way to North America. Or, more (or as) likely at that time, colony collapse was starting to be a phrase entering more common usage in 1966-ish. The funding must have continued upwards from around 1965.  

That is my guess.
