 in 1970, in wing traps placed around fields with and without growing 

 cotton. J. Econ. Entomol. 64: 559-560. 



Wlien wing traps were placed around isolated fields with and without growing 

 cotton the numbers of Anthonomus grandis Boheman that were captured were 

 correlated with the traps at both fields regardless of the presence of cotton. 

 Tlie numbers of weevils observed in the cotton field were not correlated with 

 the numbers of weevils captured on the traps.

 attraction of wing traps and cotton trap plots baited with male boll 

 weeviis for overwintered weevils. Ann. Entomol. Soc. Am. 64: 530. 



Small plots of cotton containing male boll weevils were compared with wing traps 

 containing male boll weevils for early season attraction to overwintering boll 

 weevils. In general the cotton plots were difficult to establish and much less 

 attractive to boll weevils than the wing traps.

When wing traps baited with male Anthonomus grandis Boheman were placed around 

 small cotton fields in a ratio of 1 trap per 2 to 3 acres, a positive correlation 

 was found between the number of overwintered weevils captured and the number ob- 

 served in the field. However, the estimate obtained by sampling the number of 

 weevils hibernating in woods trash did not correlate \-d.th the number captured or 

 observed. The location of traps in relation to overwintering sites influenced 

 the captures on the traps, and time of entry of weevils into the fields appeared 

 to be related to the beginning of fruiting by the cotton.
