RED SPIDER ( Tetranychus telarius L.) 
H, B. Peirson (August 24): Red- spiders are on spruce, Crataegus, 
elm, yellow "birch, oak, and amelanchier in many parts of the State, 
' H. C. Severin (August 20): The red spider is exceedingly 
abundant and injurious,, 
C. lakeland (August 20): The common red spider is extremely 
abundant, since the year is excessively dry. It is affecting 
practically all cultivated plants including shade trees and 
ornamentals. It has done very severe injury to potatoes, and 
beans as well as to the crops ordinarily affected by it. 
G„ P. Knowlton (August 18): The common red spider has been 
damaging raspberries, corn, beans, chrysanthemum, dahlias, peas, 
roses, and tomatoes in various northern Utah localities. 
D. C. Mote (August 15): Orchard mites are unusually abundant 
this year and doing serious damage to pear foliage in the 
Willamette Valley. Reports from other sections of the State 
indicate this to be a favorable season for mites, damage being 
reported on apples, pears, raspberries, muskmelons, prunes, and 
strawberries^ 
PACIFIC RED SPIDER ( Tetranychus pacificus McG.) 
E. A. McGregor (August): It is of interest to record that 
during the period from April to July, inclusive, the Pacific 
red spider ( Tetranychus - pacif icus. McG.) occurred in unusual 
severi'JIy in central California, causing much damage to vineyards jond 
deciduous fruit and ornamental trees. In early August, the 
predacious thrips y Scolothrips sexmaculatus Perg., ended the 
outbreak. This annual phenomenon . in central California is very 
interesting, since toward the climax the thr>ps population 
builds up so rapidly that the biological control appears almost 
to 'amount to instant annihilation. • 
JAPANESE BEETLE ( Popillia japonica Newm. ) 
L. A. Stearns (August 24): Many reports of injury, especially 
on grape, in the vicinity of Wilmington. 
E. W. Mendenhall (August 2l): It is reported that the 
Japanese beetle was found in Cleveland and Columbus in small 
numbers, on flowering plants. These were trapped by Japanese 
beetle scouts, 
ASIATIC GARDEN BEETLE (Aserica castanea Arrow) 
S. P. Eel.t (August 21): A specimen of the Japanese garden 
beetle, Aserica castanea Arrow, was taken at Stamford.
