Kans. Factors Influencing European Corn Borer Populations , Measure 



annual populations and observe changes in population in Kansas as 

 compared to other north-central states; learn presence or absence 

 of syncronization of changes in population; and study influence of 

 weather conditions, biotic-contr oiling factors and soil management 

 on borer populations* 

 Ent. 440 (NC-20) 



Kana# Development and Testing of Rapid Inspection Methods for 



Insect and Rodent Contamination in Wheat and Wheat Products 

 Suitable for Market Grading * Originate, develop, and test 

 techniques to learn presence of internal insect infestation 

 and contamination due to rodents in grains suitable for use 

 under United States Grain Standards*

Ky. Life History and Control of the European Corn Borer 



(Pyrausta NoMlalia) with Special Reference to Field Corn . 

 To (1) determine habits of corn borer under Kentucky conditions, 

 number of generations a year, relative damage to field corn on 

 different dates and comparative resistance of new and old inbred, 

 single cross, and double cross corns to attack; (2) aid in control 

 by distributing borer parasites and making parasite surveys, 

 find out extent of spread and abundance of corn borer, and 

 find out what other hosts are attacked besides corn*

*?* Biology and Control of Soil Insects Attacking Corn and 



Studies of the Effects of Soil Insecticides on Corn * To (l) 

 determine relative harmful effects of soil insect pests of corn; 

 (2) study relationships of crop rotations or cultural practices 

 with soil- insect populations; (3) evaluate control measures; 

 (4) study effects of insecticides on development of the plant*

Minn* Corn Improvement * To study (l) production of improved hybrids 



for the various maturity zones in the State; (2) relative value of 

 various methods of breeding; and (3) methods of field plot technique 

 and improved practices*
