128 MONTANA EXPERIIVrENT STATION 



HYMENOPTERA 



Poplar Leaf Folder (PontaJiia hozemani Cooley). Several let- 

 ters were received asking how to control this shade-tree pest. 



The Honey Bee (Aphis mellifera L.). Numerous inquiries 

 were received relative to beekeeping. The presence of the bee moth 

 and foul brood in some sections of the State emphasizes the necessity 

 of apiary inspection. 



THE AliFALA WEEVIL 



In previous reports attention has been called to the presence 

 of a very injurious pest of alfalfa, known as the alfalfa weevil, in 

 Utah, Idaho and Wyoming. This insect has continued to spread 

 toward Montana and in the territory previously occupied is as 

 injurious as ever, excepting where effective control measures are 

 in operation. 



So far as we know the alfalfa weevil is not yet in Montana. 

 That part of Montana which lies along the Oregon Short Line Rail- 

 way from Butte to the State line appears to be most liable to get 

 the weevil first and accordingly a careful search was made last June 

 in this locality to determine if it was present. An assistant was 

 sent to examine alfalfa fields and wild growing alfalfa in this terri- 

 tory. Eighteen days, from June 24 to July 11, were spent by this 

 man, making careful search for all stages of the weevil and sending 

 in the various kinds of insects that were found. He went on foot 

 from field to field and from town to town along the tracks. No 

 trace of the weevil was found and it is quite clear that at least there 

 is no well established colony of the pest in the country which he 

 searched. If this locality through which trains that have come out 

 of the infested territory in Utah pass daily has no weevil it is 

 probable that none yet occur in Montana. 



THE QUARANTINE LAW
