CALIFORNIA ROOT BORER ( Prionus californicus Mo't&cfr. ) 
C. F. Xnowlton (April 2B): The California prionus is seri- 
ously damaging cherry trees on several farms in Davis County. 
A DASCILLID ( Dascillus -plumb eus Horn) 
F. H. Wymore (April 25): This beetle was found to attack 
the buds and young leaves of small, recently planted cherry 
trees at Fairfield. As many as 10 beetles were removed from 
some of the small trees. Two-year-old cherry trees growing 
just across a small creek were not attacked. 
PEACH 3AHK BEETLE ( Fhthorophloeus liminaris Harr.) 
J. N. Knull and G. S. Ferry (May 3): Many wild black cherry 
trees in the vicinity of Burning Well, Elk County, are heavily 
infested. The infestation occurred in the fall of 1931 and is 
due to an unhealthy condition of the trefs. Increment borings 
showed slow growth for the last few years. 
BLACK CHERRY APHID f Myzus ceragi Fab.) 
S. 0. Essig (May 20): Black cherry aphids arc very abund- 
ant and destructive in the San Francisco Bay district. 
COMMON RED SPIDER ( Tetranychus telarius L. ) 
Idaho C. Takcland (May 21): May 11 no red sniders could be found 
emerging around the bases of cherry trees in the Lewiston dis~ 
trict but on May 19 they were found abundantly on the lower 
leaves and many eggs had then been deposited. The red spider 
has caused extremely severe damage to cherries in this dis- 
trict during the t>ast two seasons and the outlook this year 
is for a repetition of damage in orchards where control is 
not obtained early.
