A feeding test was made with beetles in lots of 50, using twigs 
bearing fruit and foliage from sprayed trees in the orchard, except 
in case of lot 6, where foliage had been removed. Trees were sprayed, 
April 4 and 5, with arsenate of lead at the rate of 2 pounds to 50 gal- 
Tons of water, and feeding tests started April 5, except with lots 7 
and 8, which were started April 7. It will be noted that all the 
beetles on the sprayed branches were killed within about a week, 
except lot 6, where fruit only was present and the period was length- 
ened. (See Table XCIII.)
