 Entomql. 69: 189-191. 



Adults of Anthonomus grandis Boheman moved into trap crops established during 

 the period when th'^ cotton was being harvested. These "fall trap crops" were 

 specific rows wit'. in the cotton field which remained unmodified during the 

 harvest procedure vKile the remaining portion of the field was treated and 

 harvested in the normal manner. Trap crops established in picker-harvested 

 fields attracted the greatest number of adult boll weevils. This was especially 

 true of trap crops augmented with synthetic pheromone, Grandlure®. Less move- 

 ment of weevil adults into fall trap crops established in stripper-harvested 

 fields was observed. The greatest amount of movement mnto fall trap crpps 

 occurred during the initial 24 h after the trap crops were established. 



744. , and Bird, L. S. 1977. Field studies of boll weevil resistant cotton 

 lines possessing the okra leaf-frego bract characters. Crop Sci. 17: 

 431-433. 



Cotton lines ( Gossypium hirsutum L.) possessing the okra leaf (L°L°) - frego 

 bract (fg fg^ characters were evaluated in a 3-year field study in the Coastal 

 Bend area of Texas. Two locations were used in 1974 and 1975 and one loca- 

 tion in 1976. The number of squares (flower buds) with boll weevil ( Anthonomus 

 grandis Boheman) ovipositional punctures was recorded on a total of forty 

 cotton lines. Cotton lines possessing the okra leaf-frego bract characters 

 averaged about 60% fewer boll weevil ovipositional punctured squares than the 

 broad leaf - normal bract cottons.
