SAN JOSS SCALE (AsjDidiotus perniciosus Corns t. ) 
Massachusetts A. I. Bourne (March 16): The San Jose scale, which for a few 
years seemed to he increasing to some extent, has very largely 
• subsided as a pest of prime importance. "Thile it is still 
present, it is not causing any anxiety* Apparently a very general 
use of oil sprays made necessary by the rapid spread of the 
European red mite throughout Massachusetts lias automatically 
controlled the situation, as regards the San Jose scale.

L. Haseman (March 10): This pest continues to be at a lo"" ebb 
with a tendency through central Missouri to pick up in numbers. 
Our fruit growers have it completely under control in all 
commercial orchard centers. 
OYSTER- SHELL SCALE ( Lepidopsaohes ulmi L. ) 
D. 3. Whelan (March 15): A badly infested specimen of a pest 
on a pole bark was sent from Howells, Colfax County. 
EUROPEAN RED MITE ( Pqratetranychus pilosus Can. & Fanz. ) 
A. I. Bourne (March IS): There seems to be a heavy infestation 
of the European red mite throughout practically all sections 
of the State. This, of course, i£ based on the evidence of the 
overwintering eggs. Although many growers secured good control 
by the use. of oil sprays a year ago, there seems to have been 
sufficient increase over the State as a ""hole so that reinfes- 
tation took place quite rapidly.

T. D. Urbahns (March 22): The blister mite Eriophyes pyri 
,TT as active under the bud scales, and eggs were being deposited 
on pear at Penryn. (March 29): The pear leaf blister mite has 
caused considerable damage to pear buds in the Sacramento, 
Napa , and Suisun Counties on account of the mild winter ter. 
The mites continued active under the bud scales. Spraying in 
full cluster bud is just beginning.
