moths where they occur in abundance. Tlie mixture is usually put 

 in dishes and placed in differeut parts of the field in such a way as 

 to be easily accessible to the moths. Extensive experiments of this 

 kind were made in the south by Mr. Mally,^ who reports that the 

 usual methods of utihzing poisoned sweets against this pest are evi- 

 dently useless and moreover expenditures of time and money which 

 are practically an entire loss. This conclusion is based upon the 

 behavior of the moths towards the sweets during the egg-laying 

 period. That time over, many individuals may be caught, but then 

 their capture has no real economic significance. 



It may be here added that Mr. Mally experimented extensively in 

 the south with poisoned sweets sprayed upon a trap crop, usually 

 cow peas, which were planted early enough so as to bloom about the 

 time the moths of the first brood were ready to deposit eggs. That 

 this method of treatment would be practical on the small farm, and 

 especially with the truck farmer, has not yet, so far as we are able 

 to learn, been demonstrated. Of course the trap crop upon which 

 the poison is sprayed would be of no value as a forage crop, and, 

 imless decidedly favorable results were obtained, it is doubtful, we 

 believe, whether the experiment would be a success in the truck 

 farming communities of the State where the corn-worm is most 

 numerous.
