on the propensity of PCs to 

 crawl upon sprayed traps. 

 For comparative purposes, 

 in 2000 the insecticide 

 evaluated was Guthion®, 

 and in 2001, Imidan* was 

 used (same dose as above). 

 PC behavior was observed 

 inside of Plexiglas cages 

 with no top. Traps 

 evaluated were as 

 described above, but we 

 also evaluated sprayed and 

 unsprayed apple tree limbs 

 (diameter: 2 inches; length: 

 12 inches). No attractive 

 odors were used in these 

 tests. In all instances, 

 observations were performed 1 

 limbs (taken from trees in the 

 application of insecticide. For 



-3 days after traps or placed a PC on the floor facing one of the test traps 

 orchard) received an and recorded, for a time period of up tolO minutes, 

 the observations, we whether the PC was able to reach the top of the trap.
