It has not been abundant over most of the infested area but in several 
tovms severe defoliation of ne^^lected apple orchards has occurred," (A. F,

ORIENTAL MOTH 
"The oriental moth ( Cnidocanpa f lavescens V/alk, )\7as abundaht during 
the suTJTier in several localities in the suburbs of Boston, No intensive 
work to determine the dispersion of this 'insect v/as done by the FederAl 
force?, but occasional observations showed no great amount of spread. .It was 
reported during the sur:rner causing damage in several to\7ns, including 
'.Tinthrop, Everett, and V/eymouth, and was observed as far north as Saugus 
and Salem." (a« Burgess, Bureau of Entomology, S, D* A.) 
SATIN MOTH 
During the past season the satin moth ( Stilpnotia salicis L, ) has 
made extensive advances along the periphery of the infested area. It has 
advanced northeastward into Penobscot County, Maine, westward to th§ 
eastern border of Vermont in \7indsor and Windham Counties, to within one 
county of the western border of Massachusetts, and half way across the 
State of Connecticut, Last year this insect extended as far west as Nashua, 
N» E^, Leominster, Mass,, and Providence, R. ll» Popla.r and willow trees 
were severely defoliated in a large part of the infested territory, 
BARK BEETLES 
"The epidemics of the western pine beetle ( Pendroctonus brevicomis Ladi) 
which in 1927 reached unprecedented proportions in southern Oregon and 
northeastern California, show a marked decline this year. On a large area 
in northeastern California centering around the Modoc National Forest this 
insect destroyed approxiiaately 1 per cent of the stand in 1921, The in- 
festation gradually increased until in 1927 about 3g per cent was destroyed. 
Practically 10 per cent of the volurae of timber on the s-urveyed area, or 
roughly some 500,000^000 board feet, was destroyed* Cur surveys in the 
suEimer of 1928 show that the losses will be less this year than in any year 
since 1921, The exact figures on the extent of the decline are not yet 
available. 
"The infestation of the m.ountain pine beetle ( Pendroctonus monticolae 
Hopk,) in lodgepQle pine, which has been progressing southward along the 
Continental Divide since 1909, has for the past two years been centered 
on the Bitterroot National Forest of Montana. The control project initiated 
by the Forest Service in the BigholiS Basin in an attempt to keep this 
epidemic from spreading to the east side of the Continental Divide and into 
the Madison, Gallatin, and Targhee National Forests will have to be abandoned. 
The beetles have continued to spread into the zone of defense in such nurabers 
that the attempt to check their advance is hopeless. 
"An epidemic of the Black Hills Beetle ( Dendroctonus ponderosae 
Hopk.) on the Colorado National Forest has completely subsided owing to the 
effective control measures carried out.
