]0 MONTANA EXPEEIMENT STATION Bui. 139 



tinually exists that the insects may be introduced, it is wise fur 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 w^est have established quarantines against 

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

 AA'yoming. 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. AA'lien 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 jNIontana. It is 

 the pvtrpose 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 contrcJ 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 P3xperiment Station has still a\-ailable a bulletin on the 

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

 This 1)ulletin was prepared se\eral years ago and since its pul:>lication 

 methods of control have l)een improved. The principal means of 

 control as now practiced is to spray alfalfa fields with arsenicals. 



SUGAIJ-BEET WEBWORM 



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

 sugar-beet webworm (Lo.xoste^e sticficalis) has been widely preva- 

 lent in Mont;ina. This insect continued in remarkaljle numbers in
