In Carbon County, Wyo., sweeps were taken in 11 fields and 4 of 
these fields were found to be infested. The purpose was to determine whether 
the alfalfa weevil occurred in rather isolated areas of a county already known 
to support infestations* The sweeping in the Saratoga area showed a light 
but general infestation, the alfalfa weevil being taken from 3 of 4 fields 
swept. Our survey methods showed only 1 field infested of the 7 swept in the 
Encampment area but intensified sweeping would doubtless reveal a general and 
very light weevil infestation there also. The results are summarized in table 
2 .
