Tenn. A Study of the Life History. Ecology, and Control of Army 



Worms. Pseudaletia Unipuncta, and Related Species * To emphasize 

 the various ractors governing the abundance of this species, 

 which appears suddenly and sporadically, inflicting damage before 

 the farmer is aware of their presence, so that with a better 

 understanding of these factors it may be possible to forecast 

 outbreaks. 



Ent. 97 (S-25) 



W. Va. Cereal and Forage Crop Pests -- Their Distribution. Incidence 

 and Control in West Virginia . To (1) determine distribution, 

 incidence and to estimate the economic importance of the principal 

 field and forage crop pests (insects, mites and nematodes) in the 

 State; and (2) devise effective control measures for those pests 

 found to be doing economic damage* 

 PI* Path*, Ent. 80 



Wis. The Role of Ecoxogjcal Factors in Outbreaks of the Potato 



Leafhopper * To (1) cooperate on regional pro.lect. (2) obtain 

 records of first appearance of the leafhopper and follow its 

 seasonal abundance, (3) evaluate more accurately the environmental 

 and physiological factors that determine leafhopper populations, 



(4) associate seasonal populations with regional leafhopper survey 

 and develop system for predicting normal and abnormal populations, 



(5) develop consistent method to forecast outbreaks with higher 

 degree of accuracy* 



Ent. 196 (NC-29) 



II. Cereal Insects 



Ark* Biology and Control of the Southwestern Corn Borer in 



Arkansas , (1) Further development of cultural and insecticidal 

 control for southwestern corn borer* Project will include a 

 study of severity of damage in different areas of state* 

 Ent*, Agron* 350 



Ark* Ecology and Control of the Sugar Cane Beetle (Rough-Headed 



Corn Stalk Beetle) * To (1) develop an effective and practical 

 insecticidal control, (2) arrive at an understanding of insect's 

 ecological needs as a prerequisite to control through management, 

 identifying areas prone to attack, and learning conditions 

 favorable for outbreaks* 

 Ent. 458 



Fla. Corn Breeding . To (1) breed improved corn hybrids, with 



emphasis on higher yields, better standability, and more insect 

 and disease resistance; and (2) study comparative efficiency of 

 different breeding methods.
