-399- 
oriental moth (C nido campa flavescens Walk.) remains about the same. 
It is present in the towns and cities near Boston, occasionally causing 
severe defoliation of trees and shrubs in this area. It has spread 
slowly but there was no noticeable spread of this insect recorded 
during the season". (Plant Quarantine & Control Administration, U.S.D.A. ) 
tent Caterpillars 
The Great Basin tent caterpillar ( Mai aco soma fragilis Stretch) has 
been so numerous around Mt. Shasta, Calif., this year that trains on the 
Southern Pacific Railroad were detained by the worms on the rails, it 
being necessary to equip the engines with steam j^.ts to clean the track 
in front of the wheels. In western Washington the forest tent 
caterpillar (H. disstria Hbn. ) and the western tent caterpillar (M. 
oluvialis Lyar) wer~ more numerous than they had bc^a at any time during 
the last several years. Fruit tre.s, shrubbery, and shade trees were 
badly defoliated. In the city of Seattle these insects were so numerous 
that street cars were stop-oed by the insects on the rails. 
SPRUCE BUDWORM 
The spruce budworm ( Harmologa fumiferana Clem.) was reported in 
scattered localities in Wisconsin, Minnesota, South Dakota, and North 
Dakota. The South Dakota outbreak was the second that has been observed 
in recent years in that State, An infestation of lodgepolo pine, 
involving from 75 to 100 square mil^s in the southwestern portion of 
the Yellowstone National Park and the adjoining Targhee National 
Forest, continues unabated, although there is evidence that in areas 
which have been infested for three years there has been a marked 
diminution in the number of insects so that relatively few trees will 
be killed. The forest officers report reduction in the numbers of 
this insect on the Idaho and Payette National Forests whore it has been 
especially destructive to fir for the last few years. The outbreak 
centering along the Shoshone Canyon and the eastern entrance to the 
Yellowstone national Park continues unabated. Apparently a con- 
siderable percentage of the fir in this canyon will be killed. Other 
outbreaks which have been reported from time to time in Yellowstone 
Park have almost completely subsided. Some local feeding was found in 
the fir type of the Co^ur d*Alene and Colville National Forests. This 
insect has continued active in the jack pine forests near Higgins Lake, 
Mich., and has done considerable damage, although no accurate estimates 
of abundance or injury are available. 
TIP MOTH 
The parasite Campoplex frustranae Cushman of the pine tip moth 
( Rhyacyonia f rustrana bushnelli Busc>), which was introduced into the 
pine plantations at Halsey, Neb., in 1926, has shown remarkable 
increase in the last three years. The tip-moth infestation at points 
of parasite introduction has been reduced from 92 to 2-3 per cent during 
thir period.
