110 SEVENTEENTH Report STATE ENtToMoLoGist oF MinNEsSoTA—1918 
The food plants are red clover, mammoth and medium, crimson 
clover, bur clover, and alfalfa. Alsike, white clover and sweet clover 
are apparently immune. 
The injury is caused by the larvae devouring the contents of the 
seed. The greatest amount of damage to clover seed recorded in Minne- 
sota is 39 per cent. In other sections of the country, especially where 
alfalfa is grown, the injury is often much worse, 85 per cent being 
recorded in one instance. 
As a preventive measure, the first crop of medium red clover 
should be clipped or cut early for hay to prevent the first generation of 
seed chalcids from depositing their eggs. Neighborhood co-operation 
in this should be urged. First year clover should be kept from bloom- 
ing and volunteer clover destroyed.
