to place additional emphasis on thore areas where the pilot experiment identified 

 a particular need for research. Significant research progress has been made durinj 

 the past two years in a number of areas. I will comment on progress in four areas; 

 mass rearing, sterilization, pheromones, and an insect growth regulator. 



761. . 1977. Future outlook for chemical and biological control of cotton 



insects. Summary Proc. 1977 West. Cotton Prod. Conf., pp: 68-69. 

 There is a wide range of chemical and biological methods which are potentially 

 useful in the control of cotton insects. Although there are different approaches 

 to classification of these methods, the chemical methods might include (1) 

 insecticides, (2) insect growth regulators, (3) behavior chemicals, (A) plant 

 growth regulators, and (5) harvest aid chemicals, whereas the biological methods 

 might include (1) parasites and predators, (2) pathogens, (3) autocldal control, 

 (A) host plant resistance, (5) rapid fruiting varieties, and (6) cultural prac- 

 tices. However, in order to effectively utilize one or more of these methods, 

 a number of management techniques should be utilized. These techniques are 

 sometimes referred to collectively as "decision-making technology." For the 

 purpose of looking at the immediate future, with particular reference to western 

 cotton production, I will concentrate on five topics, namely, insecticides, 

 behavior chemicals, host plant resistance, genetical control, and decision- 

 making technology. Some very important work with plant growth regulators will 

 be discussed later this morning by another speaker. Also, since we are lookiug 

 at cotton insects primarily as they affect western cotton production, the in- 

 sects of most concern are pink bollworm, lygus bugs, bollworm/tobacco budworm, 

 and spider mites. In order to relate my comments to current practices, perhaps 

 it would be helpful to briefly review insect control costs in the western cotton 

 growing areas. As most of you know, cotton insects are not a major problem on 

 the High Plains of Texas, and, consequently, insect control costs are minimal. 

 However, we also recognize the importance of continuing actions to prevent esta-
