In the experiments shown in the preceding tables, a total of 26,496 

 hoppers were recorded in 2497 separate counts. With data on this 

 large number of individuals, certainly fairly accurate conclusions can 

 be drawn. The totals for these six experiments show that of these 26 

 flavor combinations used, black strap molasses without additional flavor 

 attracted more hoppers than any other, apple and black strap molas- 

 ses being second, and the check (wet bran) third. 



The advantage of using the well known citrus fruit flavors is not 

 borne out here as in every case those combinations containing 

 citrus fruits were well down the list when taken in the order of the 

 total nirmber of hoppers attracted in the six experiments, even the 

 check (wet bran alone) giving a much better total than any of these. 

 Since the check ran so high in the list, one might well think that there 

 is nothing gained by the use of any kind of flavors or syrups in poison
