by September 1. This represented only 19 percent of the surveyed area. An 

 average of 58 adult weevils per acre was reached by September 1 when the sur- 

 vey was completed.

 in Kent and Dickens Counties in 1967. Tex. Agric. Exp. Stn. Dep. Entomol. 

 Tech. Rep. 15, 13 pp. 



Boll weevil population studies were conducted in 62 fields in Kent and Dickens 

 Counties during the summer of 1967. Survey data indicated that overwintered 

 weevil populations were very small and localized. Weevil populations in the 

 surveyed fields showed a smaller rate of Inc^-^ase between the first and third 

 generations than in 1966, however, the population in 1967 developed to a greater 

 size than in 1966. Also, infestations were detected in a greater percentage of 

 surveyed fields than in 1966. Infestations generally remained at sub-economic 

 levels during the surve ■ period.

 operation and economic impact. Tex. Agric. Exp. Stn. Misc. Publ. MP- 

 1276, pp. 152-159. 



Each year since 1964, a suppression program has been directed against the boll 

 weevil, Anthonomus grand is Boheman, population along the juncture of the Texas 

 High and Rolling Plains. The suppression effort has successfully prevented the 

 westward spread of the pest into the more than 2 million acres of High Plains 

 cotton. This program represents the largest coordinated effort ever undertaken 

 to combat a cotton pest. It also serves as an excellent example of cooperation 

 among state and federal agencies and producers.
