Other Insects 



Like other grasses and small grains, Sudan grass is subject to attack 

 by grasshoppers, cutworms, army worms, grub worms, etc. It is 

 also to be expected that the stored seed will be found subject to attack 

 by the usual seed-infesting insects, such as the saw-toothed grain- 

 beetle, the granary and rice weevils, etc., but instances of such infesta- 

 tion have not yet come to our attention. 



President H. T. Fernald: The next paper will be presented by 

 Mr. S. J. Hunter. 



SOME ECONOMIC RESULTS OF THE YEAR 



Bees and Poison Bran Mash; Army Worms; Intermittent 

 Seasonal Spraying 



By S. J. Hunter, University of Kansas, Lawrence 



To economize time, it has seemed desirable to summarize some of the 

 economic work of the year under the one general head, rather than to 

 present the same in several papers. 



In the conduct of any field campaign, objections to some feature, 

 as every entomologist knows, are likely to be raised, and these objec- 

 tions, to secure the undivided support of all concerned, have to be 

 met. 



Objections regarding the danger to stock through the use of arseni- 

 cal poisons are of common occurrence. Two years ago, during the ex- 

 tensive use of the poison bran mash against the native grasshoppers, 

 the question was frequently asked as to what effect the poison would 

 have on bees, when distributed through a large alfalfa field where bees 

 from large apiaries were at work. Last summer, Professor Caesar, of 

 Ontario, wrote me that similar inquiries came to him from Apiarists. 

 Under date of July 24, last. Professor Caesar writes: 



The bee-keepers of Ontario are alarmed at the supposed danger to the bees which 

 they believe attends the use of your remedy for grasshoppers. I have used this 

 remedy this year and saw no bees feeding on it. It has given good satisfaction as a 

 treatment for grasshoppers. I should, however, be very pleased if you would kindly 

 let me hear, as soon as possible, whether bees have been poisoned by it to any extent 

 in Kansas. Sincerely, 



(Signed) L. Caesar. 



In order to satisfy ourselves even more fully on this subject, Mr. 

 George H. Vansell, our Apiary inspector, undertook a series of experi- 

 ments to determine whether the bees would feed at all on the poison 

 bran mash; and if so, under what circumstances, and with what results.
