 in the olfactomer at that location. The petri dish was handled for 15 min prior to 



insertion into a port of the olfactometer. Testing typically occurred at approximately 

 10:00 a.m. for each of the days. The testing was conducted with 75 (six-to-eight-day- 

 old) female ^e. aegypti mosquitoes. The relative humidity, air temperature, and gas 

 flow were controlled throughout each analysis. Over the five day period, none of the 

 75 mosquitoes tested each day were collected in the control port. The lowest 

 collection percentage (12%) occurred on the first day (Monday). The remainder of 

 the week, from Tuesday through Friday, yielded collection percentages of 24%, 21%, 

 27%, and 20%, respectively. 



Results and Discussion 



Identification of Emanations by CI and EI MS 



Prior to reporting compounds observed in the analyses of this dissertation, a 

 compilation of compounds previously reported in the literature as being present on 

 the skin are presented in table 5-1. Compounds not expected to be amenable to the 

 manner in which analyses were conducted for this dissertation will be noted. 

 Literature sources pertaining to skin emanations are relatively scarce [102]. The data 

 compiled in table 5-1 are extracted from semiochemical work (odor analysis) and 

 government studies (space exploration) concerning the identification of human 

 dermal emanations [30,31,111]. Approximately 260 compounds, spanning a range of 

 classes, are contained in this table. These classifications will remain as consistent as
