of pest populations by various other systems of control is also necessary, 

 since different methods of control affect population trends in different ways. 

 Such understanding of the merits and limitations of different methods will 

 suggest ways to integrate the sterility method with other systems of control.

Proc. 1968 Beltwide Cotton Prod.-Mech. Conf., pp. 14-18. 

 Regardless of the method or combination of methods employed, eradication will 

 not be achieved unless the suppression measures are iapplied against the total 

 population of the insects. We cannot expect to develop a permanent solution 

 by uncoordinated individual effort, regardless of the control methods employed. 

 The boll weevil, like most insects, has a tremendous capacity to increase in 

 numbers and it can disperse readily. In spite of the extensive use of highly 

 effective boll weevil insecticides for 20 years, we continue to have as many 

 or more boll weevils at the start each spring as we had twenty years ago. If 

 we are to find and implement a permanent solution to the boll weevil problem, 

 we must keep two objectives in mind: (1) We must develop highly effective, 

 economical, and acceptable methods of control; (2) We must apply the control 

 measures against the total population in an organized, coordinated, and 

 efficient manner.

 Plans. Proc. 1971 Beltwide Cotton Prod.-Mech. Conf. Cotton Ginners 

 Jour, and Yearbook. March issue, p. 23-30. 

 Two insect suppression programs underway or planned by the U.S. Department of 

 Agriculture, the cooperating State Departments of Agriculture, Experiment Sta- 

 tions, and the cotton growers are of vital importance to the cotton industry: 

 the pink bollworm containment program under way in western cotton-growing 

 States and the planned pilot test program in the Midsouth to determine if boll
