of 395 weevils emerged at irregular intervals from the bolls held in the insectary 

 from November 30, 1964, through February 28, 1965. These and 1424 additional 

 weevils which emerged from extra bolls collected at the same time as those used 

 in the various treatments were placed in hibernation material without having fed 

 after emerging. Only 1 of these 1819 unfed adults survived the winter. Examina- 

 tion of the 2 cracked bolls in which the 2 adult weevils were found on April 15 

 did not reveal weevils developmental cells. This finding Indicated that weevils 

 present inside the bolls had not developed there. Results showed that although 

 boll weevils in this area may live either in the immature or adult stage in cells 

 in bolls for several weeks during the winter, they have little chance of surviving 

 under these conditions until cotton plants again become available in the spring. 

 Moreover, weevils that emerge from bolls in the winter after all sources of food 

 have been eliminated have very little chance of surviving.

 influence of size on capture efficiency. J. Ga. Entomol. Soc. 13: 222-226. 



Four different size traps of similar design were compared. One that has a 

 fluorescent yellow base ca. 1 liter in size compared favorably with larger 

 traps for detection and removal of boll weevils, Anthonomus grand is Boheman.

When overwintered females of Anthonomus grandls Boheman, collected from areas 

 with low and high populations of weevils, were crossed with sterile males, 

 egg hatch was reduced from ca. 9G to 10%. Percentage hatch was about the 

 same for females from the 2 areas.
