" There was a notable decrease in the activity of the western nine 
beetle ( Dend.ro c tonus brevicomis Lcc.) in the western yellow pine stands 
of Oregon and Washington due to no re favorable growth conditions during 
the past season. The epidemic in the Modoc National Forest, California, 
sided to a point lower than any reached during the last six years. 
During the period while this decline was in rogress in northern Cali- 
fornia an epidemic developed in the Southern Sierras in certain 7/ater- 
sheds of the Sequoia National Park and in the northern part of the Sequoia 
National Forest and in Coulter pine near Julian, on the Cleveland National 
Forest. This occurred in a very limited belt of timber and the infestation 
was estimated to run as high as 35 ~er cent of the total number of trees.' 
"The mountain pine beetle ( Dendroctonus monticolae Ho ph. ) continues 
to sweep through the lodgepole and white -ine stands of the Facific 
Northwest, central Idaho, and Western Montana, and practically all of the 
susceptible trees are doomed. The epidemic has waned in many places, 
having already killed over 90 per cent of the mature stands. The most 
active epidemics reported are now located on the Fremont, Deschutes, and 
Wallowa National Forests in Washington, and near the Coeur d'Alene, Kaniksu, 
Fend Oreille, and Kootenai National Forests and the Glacier National Park. 
The epidemic which has been active in Crater Leake National Park during the 
past 15 years is now nearly over." 
"The cypress bark beetle ( ihloeo sinus cri status Lee.) has caused 
more than the usual amount of damage to planted Monterey, Arizona, and 
Law son cypresses in central and southern California, .and in Arizona. 
Numerous hedge and windbreak trees have been killed ^cy the attack, and 
ornamental trees have been injured by the twig-pruning habit. In many 
infestations in the San Francisco Day district P. lucres si Hopk. is 
associated with P. cri status." 1 
SCOTCH FINS LDCANIUM 
The Scotch pine lecanium ( Toumeyella numismaticum P. & McD. ) , a pest 
which has never been previously recorded as doing any extensive injury in 
the forests of Wisconsin, appeared in very destructive numbers on Jack pine 
in many sections of the State. 
CYCLAMEN MITE 
The cyclamen mite ( Tarsonemus paJJJLdus Banks) attracted considerable 
attention in the coastal area of the San Francisco Day district in Cali- 
fornia late in the summer by s( riously infesting strawberries.
