I suspect that 48 hours is too short a time for a good drop test.  We 
used to go about a week when we used it commercially.

As we noticed I got zero for the first 24 hours, but some this morning 
and when I went out just now, I saw one or two in each of three hives 
of the six.

I am wondering if the fact that these hives I am looking at now had open
screened bottoms until I inserted the boards may have somehow had an 
influence on the first 24 hour results.

I am wondering what you mean by 'no correlation'.  I find that 
hard to believe.  Low correlation, and maybe some outliers, but none?

I notice that the correlation can be quite low in May according to Pierre,
but becomes better than alcohol by fall.  I am looking at Pierre's slides at 
http://www.honeybeeworld.com/diary/2011/diary021011.htm
That is using a statistical analysis to determine correlation, but
an quick visual comparison might reach a different conclusion.

Sorry if that is not clear.  Columns B and C are two different hives 
and the drop is on line 3, while the wash is on line 10.

Lines 8 and 12 are the calculated infestations from each method 
immediately above.
