 carboxylic acids. In particular, since preliminary attempts to measure quantitatively 

 (by weight) sample deposition onto beads were not successful, a study could be 

 conducted to attempt to do this. The protocol may consist of using a steep 

 temperature ramp to cut down on analysis time and focus only upon the carboxylic 

 acids. Beads could be quantitatively analyzed after handling by comparing peak 

 areas of target compounds from one bead, two beads, three beads, etc. 



The results from Chapter 3 demonstrated an enhancement in attraction of 

 mosquitoes to samples which had been spiked with acidic solution. An experiment 

 of interest is to spray a fine mist of acidic solution or basic solution onto handled 

 petri dishes. Various comparisons could be made between the attraction of 

 mosquitoes to the untreated handled dish, the dish sprayed with acidic solution, and 

 the dish sprayed with basic solution. An enhancement in attraction towards acidified 

 dishes for one or more species of mosquito may implicate an acid or acids as the 

 potential attractants. This knowledge could then be applicable to GC/MS assays. 



The dietary intake of a host influences compounds on the skin. It is believed 

 by some that certain foods enhance attraction. This matter should be examined by 

 comparison studies involving both bio-assay and GC/MS assay. Combining any 

 extraneous knowledge with the knowledge of what is present on the skin should assist 

 in targeting potential attractants. If a connection is observed between dietary intake 

 and mosquito attraction, then the cryo-focused GC/MS or purge and trap GC/MS 

 procedures described in Chapter 5 could be applied to this difference. If specific
