200 MONTANA EXPEEIMENT STATION 



Smoky Crane Fly {Tipida an^ustipennis) . Adults were 

 observed in great abundance during April and May in Gallatin, 

 Carbon, Yellowstone, Cascade, and Fergus Counties. 



Currant Fruit Fly {Epochra canadensis Loew.). This species 

 continues to severely injure currants. Experiments were conducted 

 with a poisoned bait but while the injury was considerably lessened, 

 complete control was by no means obtained. 



Mosquitoes (CuUcidae). Several requests were received for 

 aid in mosquito campaigns but no help other than advice could be 

 given as no funds for such work were available. Mosquitoes were 

 collected from many parts of the State and many valuable notes 

 were made on their life history. 



GOLEOPTERA 



Currant Fruit Weevil {Pseudanthonomus validus Dietz). The 

 5tudy of this little known currant pest was continued from the 

 previous year. Data were gathered which indicate that it is prob- 

 ably two-brooded. A brief account of the life history and habits 

 was read before the Atlanta meeting of the American Association 

 of Economic Entomologists and was published in the Journal of 

 Economic Entomology. 



Wireworms (Elateridae) . Many complaints of wireworm 

 injury have been received from all sections of the State. In Fergus 

 County a large acreage of winter wheat presented a condition which 

 tor want of a better name was called "yellow wheat." Fields were 

 badly spotted with yellow patches of wheat, the heads of Avhich 

 iiever filled. In some cases wireworms were found upon the roots 

 of, affected plants but a fungus was also present and it is therefore 

 difficult to name the direct cause of the yellowing. Wireworms 

 .were also found injuring corn and potatoes. Larvae have been 

 collected at every opportunity and have been sent to Mr. J. A. 

 Hyslop, who is an expert in this group. His determinations will 

 give us valuable records on our species which are of economic 

 importance. 



Herbarium Pest {Ptiniis fur Linn.). Many of the mounted 

 specimens in the herbarium were badly injured by the small white 

 larvae of this beetle. Flower heads were reduced to fragments and 

 in some instances holes were eaten through the paper upon which 

 the specimens were mounted.
