Weevil damage in 1937 occurred in 5 percent of the alfalfa 
fields in Box Elder, Salt Lake, and Sanpete Counties and anounted to 
less than 1 percent in Sevier County. The most general injury oc- 
curred in Millard County, where 50 percent of the first crop was 
severely damaged. In Box Elder County (table 6) serious damage is 
indicated for 1938, as threatening weevil populations existed in Uo 
percent of the fields during the autumn. Abundance of parasites 
promised usual effectiveness in minimizing production of new-genera- 
tion weevils from larvae on the first crop in 1938.
