ENGRAVER BEETLES (IPS SPP. 5 . •' . ’ ■ 
Outbreaks of engraver beetles, Ips .. oregoni Lee,., have been a feature of 
the 1939 infestations in pond^ rosa pine in California. . Extensive, top killing 
and group killing of pole stands, has occurred, both in cut-over reserves and in 
virgin forests. These outbreaks, nay be of importance .because in the past they 
have been found t" be the forerunner of nore sustained and serious infestations 
of Dendroc tonus . Extensive group killing of ponderosa- pine reproduction by the 
Oregon pine engraver ( Ips orogoni Eich, ) -"as noted on several logging operations 
on aid near the Ochoco, Malheur, and Whitman National Forests, of eastern Oregon. 
This is the most severe outbreak of Jt. orogoni that has occurred in the Northwest 
since 1931, when there was a similar infestation in the vicinity, of Klamath Falls, 
Oreg, 
There has been a marked increase in the numbers of ponderosa pine infested 
by Ips oregoni Lee. and Ips ponderosao - in the Blaqk Hills of South Dakota, In 
many places they are killing trees in groups of ten or mere. An epidemic by Ips 
engraver beetles and the southern pine beetle on 6,000 acres of privately owned 
lands in southeastern Jasper County, Tex., killed 24 million board' feet of nature 
loblolly pine, of which l6 million board feet were salvaged. Smaller infestation? 
of pine timber by Ips engraver beetles • occurred in- northern Florida, southern 
Louisiana, the Gulf coast of Mississippi, and in southern Arkansas, 
BUCK HILLS BEETLE r 
The infestations of the Black Hills beetle in ponderosa pine in the central 
Rocky Mountain region have in general declined appreciably during the last season, 
owing to extensive control work and to apparently natural factors. In Utah there 
is still a serious infestation ‘in ponderosa pine on the Powell National Forest, 
where it is estimated about 12,000 trees will be treated this winter. On the 
Wasatch National Forest a serious infestation was found to be developing in 
lodgepole pine, 
THE SOUTHERN PINE BEETLE 
«« 
Bendroctonus f ontalis Zinin. , which was seriously damaging pine timbers in 
the Coastal Plain of Virginia and North Carolina in 1938, subsided there to 
endemic numbers. However, in the mountains of North Carolina and Tennessee and in 
portions of the Piedmont of the .Carolina? , this bark beetle was very destructive, 
killing large areas of shortleaf and pitch pines, especially in the Pisgah Nation- 
al Forest and in the Great Smoky Mountains National Park, 
THE SMALLER EUROPEAN ELM BARK BEETLE < 
A nap showing the known distribution of the smaller European elm bark 
beetle ( Scolytus multistriatus Marsh. ) in the United States at the end of 1937 was 
included in the Insect Pest Survey Bulletin, Sunnary for 1937» Additional distri- 
bution records were given in the Bulletin Summary for 1938. Certain records made 
by Government and State workers during 1939 are of interest because they add in- 
formation to the known distribution of the beetle in this country. The finding of
