This is the first record of this species attacking humans in 

 Montana of which we have knowledge, although there are several 

 such records in the literature from other parts of the continent, 

 and interesting discussions of Wchlfahrtia attacks by Dr. E. M. 

 Walker 5 . These observations were made on the closely related 

 eastern species W. vigil Wlk. which appears to differ but little 

 from the western form W. meigeni Schin. in its biology. It is 

 thought that the above case should be recorded as it is the first 

 in the State. 



ox warbles (Hypoderma lineatum De Vill. and H. bovis De 

 G.) . — During this war period there has been considerably more 

 emphasis placed on the control of these pests than in the past. 

 What appear to be practical control measures have been worked 

 out for the first species in states to the south of Montana, but 

 there is a dearth of adequate information on the biologies of the 

 two species in this area as they may affect the controls applied. 



A cooperative project between this department and the Veter- 

 inary Research Laboratories and the Department of Animal In- 

 dustry is now gathering data on the practicability of controlling 

 warbles under Montana conditions and a considerable amount of 

 biological data are being collected. Wherever collections have 

 been made at the proper time both species have been present, and 

 it is probable that they both occur throughout the State. As soon 

 as sufficient information is available to indicate the significance 

 of these data they will be released by the cooperating depart- 

 ments. 



BIENNIAL REPORT OF THE MONTANA STATE APIARIST, 



1943-44 



During the past biennium the Office of the State Apiarist has 

 functioned in the various capacities provided by law. Its most 

 important activity is that of maintaining control of bee diseases 

 by apiary inspection. In addition the State Apiarist has acted as 

 a source of information and advice on the technical problems of 

 many individual beekeepers, assisted in keeping the bee industry 

 in contact with the various government agencies and regulations, 

 at times presented the cause of individuals and the industry to 

 these agencies, studied the opportunities and the utilization of 

 Montana's honey-producing resources, and also studied some of 

 Montana's needs for the services of bees in the pollination of 

 crops. 



In the previous report" it has been shown that beekeepers in 

 Montana fall into two groups, an amateur group of 600 to 700
