In Douglas County (table 13) one- sixth of the stirveyed fields 
were inhaMteji_by threatening numbers of weevils, as was the case in 
the 1936 survey. Because" of the widespread dainSge in 1937 1 develop- 
ments, especially on large alfalfa acreages, should "be watched closely 
with a view to possible insecticidal treatment, as this is the most 
satisfactory means of control for this area.. Living parasites were 
abundant and ordinarily would be highly effective were it not for the 
late cutting practiced in this district.
