 A boll weevil trapping device using a natural or synthetic chemical as an 

 attractant is commonly called a boll weevil pheromone trap. Grandlure, the 

 chemical that approximates the natural attractant of the boll weevil, is 

 widely used in the boll weevil pheromone trap. Although :fche most effective

 weevils near the High Plains of Texas. J. Econ. Entomol. 64: 14-19. 



Field Inspections and wing traps containing live male Anthonomus grand is Bohe- 

 man were used in 1968 to study the seasonal movement of boll weevils near the 

 High Plains of Texas. Peak populations of overwintered weevils occurred in 

 cotton fields within 4-5 weeks after plantinj. Movement of boll weevils began 

 early in the spring before cotton was planted, decreased greatly during mid- ; 



summer, and increased again to a very high level late in August. Relatively 

 large numbers of weevils were captured in both the spring and fall at dis- 

 tances more than 6 miles from cotton.

Eighteen compounds were evaluated for their effects on larval development 

 of oviposition or both in the boll weevil, Anthonomus grandis Boheman. 

 Methotrexate, 5-f luoroorotic acid, and 5-fluorouracil were among the most 



active compounds tested. The addition of uracil and ribonucleic acid to ^^" 



adult diets containing 5-fluoroorotic acid and 5-fluorouracil partially 

 reversed their effect on oviposition. '*" _
