blishment of the boll weevil in the High Plains. Conversely, the Imperial Valley 

 of California, primarily because of the pink bollwonn, is the highest insect 

 control cost area in the U.S. Control costs in the San-Joaquin Valley are sub- 

 stantial, but somewhat less than other areas in California and Arizona. But, if 

 the pink bollworm becomes a major pest in the San Joaquin Valley, Insect control 

 costs in thau area could increase greatly.

Control of cotton insects in the United States is becoming more difficult because 

 of (1) the increasing developj.ont of insecticide resistance, (2) the decreasing 

 availability of insecticides, and (3) the rapidly increasing costs of insecticides 

 and their application. Fortunately, research is providing a number of innovations 

 that should be useful in the management of cotton insects. Advances are being 

 made in the development of such suppression methods as resistant and short-season 

 varieties, cultural methods, biological agents (parasites, predators, and micro- 

 bial agents), genetic manipulation, specialty chemicals (growth regulators, 

 pheromones, and other behavior chemicals), and insecticides. However, effective 

 and economical cotton insect control will require intensive management of various E 

 insect suppression methods as an integral part of a. total cotton production system.

 ment trials. Proc. 1978 Beltwide Cotton Prod. Res. Conf., pp. 108-109. 



In my view, the boll weevil eradication trial and optimum pest management demon- 

 stration, which will be conducted furing the next 3 years, together with the 

 comprehensive evaluation, offer the potential for obtaining a vast amount of 

 information that can be invaluable in determining the future direction of 

 cotton insect management in the U.S. However, for this potential to be rea- 

 lized, ^continued cooperation and dedication of all interested parties is 

 essential. So, let us move ahead together.
