Improvement of Measures for Control of Insects Attack 
Farm Woodlands and Nurseries. (1) Devise practicable ways for 
detecting presence, and for recording relative abundance of 
insect and allied pests damaging farm woodlands. (2) Learn 
effect of various ecological factors that might decrease or 
increase populations of any particular species. 
Ent. 3-E 
Biology, Ecology, and Control of Termites. To learn (1) how 
colonies of termites become established in buildings; (2) relation- 
ship of soil type and moisture to distribution and abundance of 
subterranean termites; (3) rate of buildup of termite colonies 
originating from individual pairs; (4) effectiveness of different 
chemicals for use in eliminating existing termite colonies and 
prevention of subsequent termite entry or attack; (5) resistance 
of chemically treated and untreated products to termite attack; 
(6) effectiveness of chemicals applied as dusts in termite galler- 
ies in destroying termite colonies. 
Ent. 965 
The Study of Oak Wilt Caused by Endoconidiophora Fagacearum 
Bretze To TL) develop better understanding of relationships 
between causal organisms and its host; (2) determine more about 
characteristics of causal organism. (3) determine how the disease 
organism travels long distances to cause new infection centers; 
(4) develop better methods for oak wilt control under forest 
conditions; and (5) develop methods for oak wilt control under 
recreational and ornamental planting conditions. 
Ent., Bot., Pl. Path., Zool. 1047 (NC-22) 
Insect Vectors of Plant Diseases. To study (1) nature and 
extent of injury caused by toxicogenic insects; (2) ecology and 
habits of known vectors; (3) Search for new vectors; (4) Study 
chemical and other control methods of vectors.

Insects Attacking Shade Trees and Ornamental Plants. (1) 
Obtain fundamental information on biology, ecology, distribution, 
and habits of insects; (2) Study control measures; (3) Study 
relationship between drought, insects populations, and damage in 
shade trees and ornamentals.
