Ind. Insect Problems of Shade Trees, Shrubs, and Fruit Trees 



in the Nursery . To (l) develop a complete annotated bibll- 

 ography of insects attacking nursery plantings; (2) determine 

 the major pest problem occurring in Indiana; (3) investigate 

 the life history and habits of these major pests; (4) determine 

 cultural and related practices in plantings and nurseries which 

 may be factors in the presence or absence of pests, or which 

 may affect their economic importance; and (5) to find chemical 

 and/or mechanical means of completely controlling pests in 

 nurseries so that pest free plants can be grown and shipped 

 inter- or intra-state,

Kans, Insects Attacking Shade Trees and Ornamental Plants , (l) 



Obtain fundamental information on biology, ecology, distribution, 

 and habits of insects; (2) study control measures; (3) study 

 relationship between drought, insect populations, and damage 

 to shade trees and ornamentals, 

 Ent., Hort. 477 



Mass. Materials and Methods V/hich Promise Value in Control of 



Insects and Mites on Ornamental Shrubs and Shade and Forest 

 Trees . Study value of newer insecticides and miticides, and 

 applications for control of insects and mites on ornamentals 

 and forest trees.

Miss. Control of Arthropod Pests Attacking Greenhouse and 



Ornamental Plants . To determine (l) satisfactory insecti c id al 

 or cultural controls for the more important greenhouse and 

 ornamental pests; (2) species and varietal tolerance of plants 

 to effective insecticides; (3) value of plant nutrition and 

 varietal resistance; and (4) most practical application equip- 

 ment for various conditions.

N. J. Systemic Insecticides for the Control of Insects and Spider 



Mites Attacking Greenhouse Flowers, Ornamental Shrubs and Flowers 

 and Nursery Plants . (l) Learn mechanics of action of systemic 

 insecticides on ornamentals by determining: methods and rate of 

 absorption through roots, stems, seeds and forages, parts cf 

 plant to which systemics are translocated; length of effectiveness 

 of systemics. Deternine (2) types of insects and spider mites 

 which are controllable by systemics; (3) economics of control by 

 systemics as compared with previous control.
