NOTE: Some parasites and predators were released against the same hosts/prey and therefore the grand total is not a sum of the 

 figures in that column. Similarly, several kinds of beneficial organisms were released in the same States/Territories and 

 counties, and the grand totals are not the sums of the figures in those columns.
