10 MONTANA EXPEEIMENT STATION Bui. 139 



tinually exists that the insects may be introduced, it is wise for the 

 farmers of Montana to be on the lookout for this insect during the 

 next few years and insects found doing damage, suspected of being 

 from this species, should be promptly sent to the Experiment Sta- 

 tion. It will be necessary to take immediate action when this insect 

 appears. We believe there should be a fund under the control of 

 the Board of Examiners, which it may liberate to meet emergencies 

 which may arise from the alfalfa weevil or from the presence of 

 other dangerously injurious insect pest or plant disease. 



Numerous states in the west have established quarantines against 

 the states of Utah and Idaho and portions of Colorado, Oregon, and 

 Wyoming. In cases where the states have established quarantine 

 lines within the state, thereby separating the districts or counties 

 which are infested, the other states have quarantined only the 

 infested localities or counties and have allowed shipment from the 

 weevil-free counties. When in a few years Montana has the weevil, 

 as we fear she will have, it will be necessary for us to establish 

 quarantine lines around the infested localities as they appear, as 

 otherwise surrounding" states and the Dominion of Canada will 

 undoubtedly quarantine the whole of the state of Montana. It is 

 the purpose of this office to search for this weevil annually during 

 the next few vears and in case colonies are found we shall be in 

 need of sufficient funds to take the necessary steps for control and 

 for the protection of the state as a whole. It is our purpose to call 

 upon the Board of Examiners for allowances from the proposed 

 emergency appropriation, if it is made. To fully meet the situation 

 the present legislature should enact a law authorizing the Governor 

 to quarantine infested localities within the state of Montana. The 

 passage of such a law is earnestly urged. 



The Experiment Station has still available a bulletin on the 

 alfalfa weevil and will gladly send it to all who may request it. 

 This bulletin was prepared several years ago and since its publicatii m 

 methods of control have been improved. The principal means of 

 control as now practiced is to spray alfalfa fields with arsenical-. 



SUGAR-BEET WEBWORM 



For several years past an insect which has been known as the 

 sugar-beet web worm (Loxostege sticlicaUs) has been widely preva- 

 lent in Montana. This insect continued in remarkable numbers in
