some evidence that the breeding places are in neglected poultry houses. 

 They have been observed to be quite abundant around such places 

 during the late twilight hours. Observations have been made to note 

 if they attack poultry, but all have been negative. 



Aside from the annoyance of the bite of the Phlebotomus it is quite 

 probable that it is a carrier of disease. There is some evidence of a 

 circumstantial nature that is incriminating. During the fall of 1916 

 there was an outbreak of a mild form of what was termed by the local 

 physicians dengue fever, the latter part of September and in early 

 October. The outbreak was practically an epidemic. The disease 

 occurred in 1917 with a smaller number of cases. In 1918 there were 

 many cases of Spanish influenza and the local physicians are uncertain 

 as to whether any cases of the so-called dengue appeared. The fever 

 lasts about three da3^s and runs about 102°F. to 103°F. There appears 

 to be a tendency toward a recurrence of the fever each year in some 

 cases. 



GRASSHOPPER CONTROL IN KANSAS^

Special Agent, U. S. Bureau of Entomology 



During the summer and fall of 1918, the grasshopper outbreak in 

 Kansas was one of the worst in the history of the state. The out- 

 break did not come without warning, for in the previous year, in sev- 

 eral localities in western Kansas, the grasshoppers were present in 

 such damaging numbers that control measures had to be practiced in 

 order to save the crops. It was evident that should the eggs be de- 

 posited in large numbers, and should the weather prove favorable for 

 most of the egg capsules to pass the winter uninjured, the season of 

 1918 would be one of the most serious grasshopper years that the state 

 had experienced. In the fall, the Department of Entomology and 

 Extension Division of the Kansas State Agricultural College, in coop- 

 eration with the Federal Bureau of Entomology, placed an agent- in

* Mr. Scott Johnson, special field agent of the Federal Bureau of Entomology, did 

 the survey work in the fall of 1917, and assisted with the extension work during the 

 winter and early spring of 1918, at which time he entered the navy. Because of the 

 urgent need of continuing the work, Mr. A. L. Ford, scientific assistant, Bureau of 

 Entomology, on request, was transferred from the investigational work to the ex- 

 tension service. Much of the success in organizing the farmers to poison the grass- 

 hoppers and to disk to destroy the eggs was due to Mr. Ford's excellent work in the 

 field.
