Mr. W. E. Britton: I would like to ask Mr. Dean if he tried 

 this on cutworms? 



Mr. George A. Dean: The variegated cutworm, the outbreak 

 of which was discussed in my paper, is also one of the common garden 

 cutworms. Although we have not tried this poisoned bran mash for 

 the control of cutworms in gardens, we have tried the other bran mash 

 (not flavored with fruit juice) and it -proved fairly effective. Since 

 the bran mash proved so effective in the control of the variegated 

 cutworm in the alfalfa fields, I can think of no reasons why it would not 

 also be effective in destroying the cutworms in gardens. 



■ Mr. E. 0. G. Kelly: I would like to ask if the insects prefer 

 the poisoned bran over the crop they are attacking? 



Mr. George A. Dean: Yes, in many of our experiments we 

 have found this to be true. I am sorry I neglected to bring the slides, 

 which I had intended to bring and which would have illustrated this 

 very distinctly. For instance, on one side of the bran mash barrier 

 the rows of corn, about eighty rods long, and at that time the plants 

 about fifteen inches high, stand absolutely uninjured, while on the 

 other side of the barrier the corn is completely taken. In the case of 

 grasshoppers we have found that they would leave the alfalfa and 

 take the bran. In the case of army worms in alfalfa, as stated in my 

 paper, we recommended the cutting of the alfalfa and then poison 

 the worms as they migrate. In most of our work the alfalfa was 

 either ready to cut or had been cut. Personally, I would not advise 

 the scattering of it in alfalfa fields where the crop o" plants are large. 

 First cut the alfalfa and then distribute the bran mash. 



Mr. Wilmon Newell: In Texas we have used this mixture 

 extensively the past year in the case of local grasshopper outbreaks 

 and the results have been uniformly satisfactory. In one case we 

 distributed the poisoned bran mash in a field of green oats that were 

 just heading. The grasshoppers preferred it to the green oats and 

 the crop of oat hay was saved. It was impossible to cut the oats and 

 apply the mash afterwards for the weather was too wet. Its use in 

 this case saved the entire crop. 



Mr. H. a. Surface: Any effects of poisoning native birds or 

 domestic animals from its use? 



Mr. George A. Dean: I will state that in all of our distributing 

 of the poisoned bran mash we have yet to hear of any authentic case 

 of poisoning any barnyard fowl or domestic animal in any way, shape 

 or manner. We have noticed bees about it, but in no case have we 

 found them dying. No birds have been killed. Professor Dyche,
