within the same formulation, we found that traps baited 

 with the 'Great Lakes IPM' and 'IPM Tech' 

 formulations deployed outside the trap tops captured 

 3.5 and 4.5 times (respectively) more PCs than traps 

 having the same type of formulation but placed inside 

 the trap tops. For both clear and white vials, no 



differences in captures 

 were noticed between vials 

 placed inside or outside the 

 trap top (Table 1). 



In the second 

 experiment, traps having 

 five white vials placed 

 outside of trap tops 

 captured the most PCs 

 (Table 2). Traps having 15 

 vials (which released a 

 total of -37.5 mg of 

 benzaldehyde per day) 

 captured the fewest PCs, 

 only slighter more than 

 unbaited traps. Overall, 

 about four times more PCs 

 were captured when vials 

 were positioned outside of 

 trap tops than inside. 



In the third 



experiment, wherein all 

 formulations of benzaldehyde were placed inside of 

 cylinder trap tops, results indicated that during the first 

 8 days of evaluation, traps baited with one white vial 

 captured numerically more PCs than any other bait 

 treatment (Table 3). From days 9-16, clear vials 

 outperformed the other formulations. During this time
