THIKTEEXTH ANNUAL EEPOKT OF STATE ENTOMOLOGIST 15t» 



Along with this insect we ftHi.ul also sheath maggots (Afrininiizd 

 aineTicana and ,1/. ni ^riventris) which were cluing some damage, 

 but less than the stem maggots. A study (jf these maggots will 

 be continued. 



THE SPOTTED FEVER TICK 



In tlie Twelfth Annual Repi.rt of the State ICntonMliigist a 

 brief review^ of the status and organization of the work <ui the spotted 

 fever tick is given. In the past particular attention has been given 

 to the tick in western Montana where in certain locitlities the spotted 

 fever exists in its most virulent form. This work, now under the 

 supervision of tlie ^Montana State Bcjard of Entomologv, is being 

 pushed with energy and much success. Good progress is being 

 made in the eradication of the tick and the reduction of the number 

 of fever cases and deaths. 



During the season of 1915 the tick took on a new and larger 

 significance in Alontana by the appearance in the eastern part of 

 the State of a considerable number of cases of the spotted fever in 

 localities where so far as we know none had occurred before. This 

 has led to a greatly increased interest in tlie tick in several counties 

 and it is now necessary that a thorough study of the situation l)e 

 made. 



MOSQUITOES 



One of the most striking developments in official entomology 

 in ^Montana in recent years has been the increasing and insistent 

 demand for information regarding the l)est procedure to l)e adopted 

 to secure relief from mosquitoes. \\'e have had demands from towns 

 and many individuals for assistance. \'ery little has been done in 

 the study of mosquitoes under conditions such as we have in Abm- 

 tana Avhere irrigation is so extensi\ely practiced and where the 

 mosquito fauna is so different from that in eastern states. It is 

 assumed by many who write in for information that all it is necessary 

 to do is to state wliat is l)eing done in otiier localities. As a matter 

 of fact, while some "ood can be di ne bv drainage of stagnant water 

 and oiling where mosquito larvae are found, it is necessary to know 

 much more than we now do regarding the kinds of mosquitoes 

 present and the habits of the more important ones in order that we 

 mav intelligentlv meet the situation.
