Similar results were obtained when the baits were employed 

 on oats and alfalfa. 



Obviously, we could not recommend any of these to the farmers, 

 for even had they been fairly successful an application of 100 lbs. 

 per acre is too heavy to be practical on our large prairie fields. 



From notes made in 1913 we drew the following conclusions:— 



1. Cutworms in dry localities feed largely in order to obtain 

 moisture, and dry bran is not sufficiently attractive to be fed upon 

 extensively when their normial moist food is available. 



2. One species {P. orthogonia) for which we were poisoning 

 feeds almost exclusively below ground, and a surface application 

 of poisoned bait is therefore mainly wasted. 



3. Molasses gave more hopeful results than any other attrac- 

 tive agent used. 



In 1914 we tried replacing the bran with shorts, and harrowing 

 the bait in when P. orthogonia was the species present, and special- 

 ized upon the molasses mixtures. Results were most gratifying, 

 and we found that in each case the improvement was marked. 



In all cases comparative tests were made simultaneously, and 

 the following are soine of the results on Spring Wheat: — 

 A. Surface application. 



100 lbs. Bran, 1 gallon Molasses, 2 lbs. Paris Green, 4 gallons 



Water.— 26%o dead. 



50 lbs. Bran and 50 lbs. Shorts, 1 gallon Molasses, 2 lbs. Paris 

 Green, 4 gallons Water. — 43% dead. 



100 lbs. Shorts, 1 gallon Molasses, 2 lbs. Paris Green, 4 gallons
