In Sanpete County adult populations indicated considerable damage 
in 1937, one- third of the fields being menaced. Of the total. area in 
the two counties, one-fourth of the fields have menacing weevil popula- 
tions. In this county 3. - curculionis cocoons were numerous and the 
parasite promises to be effective next season, as usual. Results of 
the su.rvey in Sanpete County, sampled on November 5-7, are shown in the 
following table.

Last season weevil damage in Colorado was confined to Mesa, Delta, 
and Montrose Counties. In Mesa County 75 percent of the fields were 
severely damaged, In Delta and Montrose Counties damage was less severe 
and varied in different districts, one having 14-percent damage and 
another 90 percent. Consequently, a survey was made last fall in the 
more important districts of these counties, Mesa Coimty being considered 
as one district and Delta- Mont rose Counties as another. 
Delta County . — Adult populations indicated slight damage next 
season. No fields sampled had menacing populations but in many fields 
the numbers present closely approximated that necessary to produce damage.
