Identification and Distribution of Economic Insects in 
South Carolina. (1) Obtain taxonomic and biological information 
on cutworms, army-worms, leafhoppers, bark beetles, etc., occurring 
in South Carolina. (2) Provide and maintain adequate identification 
of species of economic importance currently encountered. (3) Oper- 
ate light traps in cooperation with ARS, and to correlate collec- 
tion with weather data. (4) Learn if it is possible to predict out- 
breaks of insects by means of trap light and field collections. (5) 
Prepare reports on seasonal and geographical data for publication.

The Structure and Function of Specialized Tissues in Insects. 
To make a basic study of anatomical features of insects, with par- 
ticular emphasis on structure and functions of (1) sensory organs, 
especially the chemo-receptors involved in odor perception; (2) 
exoskeleton as related to protection against pathogens, micro- 
organisms and insecticides; and (3) certain secretory organs.

Control of Arthropod Pests Attacking Greenhouse and Ornamental 
Plants. To determine Cy satisfactory insecticidal or cultural 
controls for the more important greenhouse and ornamental pests; 
(2) species and varietal tolerance of plants to effective insecti- 
cides; (3) value of plant nutrition and varietal resistance; and 
(4) most practical application equipment for various conditions.

pest on vegetable crops grown in glasshouses; (2) Study: condi- 
tions responsible for development of resistant strains of mites 
and insects; (3) commercial control measures, and try to improve 
them; (4) Devise control measures for newly introduced or unusual 
pests; (5) methods to induce honey bees to pollinate greenhouse 
tomatoes efficiently and consistently.
