col lections, sticky traps, Disney traps) and are of little value 

 elsewhere; others have broader utility (light traps) and can be used 

 regardless of the availability of suitable habitat. From the data in 

 Table 2-1 it appears that the latrines at Garner State Park and at 

 Fawcett Boy Scout Camp were universally attractive structures. All 

 species taken at these two sites were taken in resting collections in 

 the latrines. In other localities, where resting sites were not 

 discovered, even after extensive searching, light traps proved most 

 effective. Biting collections were effective as a selective means of 

 sampling anthropophil ic species at Garner State Park, and probably 

 would have been useful at other sites as well. Baiting of CDC light 

 traps with dry ice also selected for man biters and was the only way 

 Lu . diabolica were collected at the D'Hanis site. 



Due to the success of collections in latrine resting stations at 

 Garner State Park and Fawcett Boy Scout Camp, other methods such as 

 light trapping and bait trapping were not routinely used. 



Most sampling methods collected predominantly females, which is 

 consistent with findings of other authors (Young, 1972; Endris, 1982). 

 No males were taken in biting collections, although some would be 

 expected to mate with females on the host as she feeds. The figures in 

 Table 2-2 should not be interpreted to represent the true sex ratios 

 in the natural population. Most trapping methods, especially those 

 using light or bait attractants, select for females. This is 

 especially true if the female's movement is part of a hunting strategy 

 (Kil lick-Kendrick and Rioux, 1981). Chaniotis et al_. (1972) stated 

 that the true sex ratio could only be properly assessed by studying
