Insect Pests for Forest and Shade Trees.--A. Forest Manage- 
ment in Relation to Insect Pests of Plantations.--B. Epidemiology 
and Control of Insect Outbreaks in Forests and on Shade Trees.-- 
C. Minnesota Forest Insect Survey. To (1) facilitate prediction 
of tree insect outbreaks before they develop to the point where it 
is too late to attempt control; (2) provide basic understanding of 
natural control agencies operating to terminate outbreaks and some- 
times prevent them; (3) develop forest management procedures to 
reduce or eliminate losses resulting from insect damage; and (4) 
explore field of chemical control, both means of applying poisons 
to trees and use of newly developed insecticides.

A Study of the Effect of the Source of Seed Upon the Growth, 
Development, and Habits of Native Tree Species.--A. A Study of 
the Effect of Source of Seed and the Influence of Insects Upon 
the Growth, Development, and Habits of Jack Pine (Pinus Banksiana 
Lamb.) To study (1) effect of climatic conditions upon growth, 
development and hardiness of jack pine from various portions of 
its range; (2) effect of form of parent tree upon the progeny; 
(3) variations in seed value from different portions of trees 
range; (4) whether the characteristics of opening cones annually 
on trees is inherited; and (5) influence of insects, such as tip 
moth, pitch nodule makers, sawfly, midges and others, on form and 
development of tree and determine methods of control. 
For. 1902 
Biology and Control of Certain Insects pie Forest Trees 
and Unfinished Forest Products in Mississippi. (1) Evaluate damage 
caused by insects previously listed; (2) Study life histories and 
habits of insects listed; and (3) effect of environmental factors 
on biology and damage caused by insects; (4) Develop control 
measures for these species applicable to nurseries, forests, wood- 
lots, and unfinished wood products.

emphasis on various species of nut curculios; (2) Investigate 
biology and ecology of insects attacking acorns.

The Biology and Control of Carpenterworms and Associated 
Borers ssouri, Study the biology, taxonomy, ecology, and 
control of carpenterworms and associated borers and evaluate 
their importance as enemies of hardwoods.
