Pine beetle hazard map prepared.—~assistance of the Forest Ex- 
periment Station C W A workers at Portland has made possible the 
compiling of all data for Oregon and Washington as to the location 
and size of ponderosa pine areas. susceptible to damage by the western 
pine beetle. With the help of such a map, it is simple to integrate 
the pine beetle survey data from various pens plots in order to 
get a general picture of insect conditions in the pine region as a 
whole. Such a map combining. tyse data aA om all private land areas, 
as well as national forests, national parks, and Indian reservations, 
has deen needed for many years. The help of the C W A workers has 
made its completion a reality. 
Forest insect work in the BE OG W program.--Plans are now being made 
at the Portiand field laboratory for carrying out detailed insect 
surveys and studies under the EB CO W prosram during the coming summer. 
Most of this worsx will be in the ,ine region, but studies will also 
be conducted in the Dousias fir region in connection with snaz deteri-

Establishment of forest insects in a large isolated plantation.-—- 
The Nebraske National Forest consists ai isolated plantations near 
Halsey, Nebr. Notwithstanding the fact that the nearest native pine 
_timber is more than 50 miles distant, L. G. Baumhofer, of the Coeur 
d'hlene, Idaho, field laboratory, reports that a number of snecies 
of forest insects have been found there and that new ones are appear- 
ing from time to time. 4 few small private piantations anda wind- 
breaks have been planted in the intervening sand-hili country during 
the 30 years since the establishment of the Halsey plantation, but 
they are scattered and the forest insects are much fewer there than 
at Halsey. Fourteen pine-infesting species have been reared from 
the forest plantations. These foie: e species of tip moths, @ 
pitch moths, a cone moth, a pitch nodule moth, 2 smail moths mining 
the bases of the needles, 5 snecies of bark beetles (mostly of 
secondary importance), and a scale insect. Practically all of these 
species have been observed in the natural timber stands of north- 
eastern Nebraska. No defoliating insects have as yet been found in 
the plantations, but judging from the variety of insects already 
established it would apsear only a matter of time until they will De.
