 In the interest of developing a research game-plan which will allow us to attend 

 to the most critical needs in the shortest possible time, and yet not dampen 

 opportunities for important ancillary achievements, I have fearlessly divided 

 the research needs into three categories. Doubtless some of my colleagues will 

 take excepti'n to my placement of one or more of their projects. I invite such 

 scientists to try to persaude me to change my mind. In setting priorities for 

 boll weevil research, it seems helpful to divide the research objectives into 

 three categories, or arrays. The first is the critical array which includes 

 only those research objectives which are absolutely essential to obtain major 

 new improvements in the reliability and economy of the boll weevil suppressive 

 system. The second group of research objectives is the concurrent array . 

 Achievement of objectives in the concurrent array seems fairly certain, and 

 although such accomplishments are not absolutely essential, they would be very 

 helpful in further increasing the reliability and economy of the suppressive 

 system. The third group of research objectives is the supplementary array . 

 The supplementary array contains high-risk objectives as well as those which 

 may or may not prove to be important or needed. These high-risk objectives 

 could result in substantial improvements, but we dare not rely on their 

 accomplishment at this time.
