ELEVENTH ANNUAL REPORT OF STATE ENTOMOLOGIST 13o 



and should throw light on other important points. 



It now appears that we have another reason for being interested 

 hi this tick, which a few years ago was regarded as scarcely more 

 than a source of annoyance to persons who had occasion to go into 

 brush and pastures in the spring. 



Dr. I. U. Temple of Pendleton, Oregon, Dr. Seymour Hadwen, 

 pathologist to the Dominion Department of Agriculture, Agassiz, 

 B. C, Canada, and others have called attention to what is apparently 

 a well marked new disease, known as ''acute ascending paralysis" 

 or "tick paralysis." 



This disease follows the bite of the tick and the location of the 

 bite on the body seems to have much to do with the occurrence of 

 the disease, as in these cases the bites are generally at the base of 

 the skull or along the spine. Recovery of the patient is surprisingly 

 rapid after the removal of the tick, and an early removal of the tick 

 seems to prevent death. Most of the cases are in children. 



The cases that have been reported so far have been mainly in 

 northeastern Oregon and in southern British Columbia. It would 

 be interesting to determine if cases have occurred in the territory 

 between, in the State of Washington. Tick paralysis is of rare 

 occurrrence in Montana, but a few cases have been reported. None 

 liave occurred in the Bitter Root Valley so far as we know. 



Doctor Hadwen has called attention to what is probably the 

 same disease occurring in sheep in British Columbia. In a band 

 of 900 sheep at Keremeos many died and manv more were affected. 



FEATURES OF THE YEAR'S WORK 



Some of the main features of the season's activities in the 

 entomologist's office were the work on the alfalfa weevil and on the 

 spotted fever tick, the latter being done through the State board of 

 entomology. These two lines alone absorbed much time. 



In addition to these, work was done on the insects which were 

 mentioned in the last annual report as requiring immediate attention, 

 and many conferences have been held with the State horticulturist, 

 with whom this office is always in close cooperation. 



An assistant was sent to the extreme east end of the State to 

 look into grasshopper conditions and to advise with farmers regard- 

 ing conrol.
