 effectiveness of diflubenzuron and azinphosmethyl • f or control of boll 

 weevils. Southwest. Entomol. 4: 315-320. 



Eight applications of diflubenzuron at rates of 35, 70 und 140 g Al/ha resulted 

 in a seasonal average adult boll weevil emergence of 44.4, 40.0, and 27.0 per- 

 cent, respectively. Adult weevil emergence from untreated cotton check plots 

 averaged 73.5 percent. Under conditions of heavy weevil infestation, lint 

 yield data indicated the 70 and 140 g Al/ha rates to be equal in effectiveness 

 to 8 applications of azinphosmethyl at a rate of 336 g Al/ha. All rates of 

 diflubenzuron were less detrimental to selected beneficial arthropods than 

 azinphosmethyl.

 diapause boll weevil control program on the High Plains of Texas. Tex. 

 Agric. Exp. Stn., Dep. Entomol., Tech. Rep. 8, 11 pp. 



The third year of an insecticidal spray program aimed at reducing the diapausing 

 boll weevil, Anthonomus grand is Boh. , population in an eight county area of 

 the High and Rolling Plains was completed November 4, 1966. Significant pro- 

 gress has been made in reducing the boll weevil population in the area. The 

 potential overwintering population in the control zone in 1966 was estimated 

 to be 96.7^ smaller than in nearby untreated acreages. Recent examinations 

 of leaf litter in locations known to be suitable for boll weevil hibernation 

 indicated that Lhe 1966-1967 overwintering population in the treated zone was 

 extremely small. Records indicate that the potential overwinterini; population 

 in February, 1967 was 42% smaller than in February, 1966.
