It is a nistake to consider reproduction-diapause control only as a major compo- 

 nent of an eradication program. In areas where successfully tested, this control 

 method can be considered a true pest management technique. A combination of 

 reproduction-diapause or diapause control with certain cultural practices, such 

 as delayed uniform planting dates, application of harvest-aid chemicals, and 

 early harvest and stalk destruction, will produce a highly effective and econo- 

 mical pest-management system for many areas. There is considerable promise for 

 developing effective boll weevil management programs based upon the late-season 

 suppression of potential overwintering weevils in combination with short-season 

 cotton, resistant varieties, and pheromone trapping systems. 



790. . 1980. Effectiveness of diflubenzuron (Dimilin) for boll weevil 

 suppression in Texas. Southwest. Entomol. (Preface.) Suppl. 1: 1. 



Herein, we review research conducted in Texas on the mode of action and environ- 

 mental fate of diflubenzuron and on its use in the suppression of boll weevil 

 populations. The IGR was tested at various rates and with different applica- 

 tion techniques in several cotton producing areas of the state. Diflubenzuron 

 was compared to conventional insecticides for effectiveness in weevil suppression 

 and for detrimental effects on beneficial arthropods. The fate of the IGR 

 after application to boll weevils, plants, and soil are discussed and sugges- 

 tions for its use in boll weevil control are offered.
