Not really. For the traps I've seen, a powerful fan pulls air from an intake pipe at a certain height above ground level through a fine steel mesh filter. You remove the filter after a certain time period, and weigh the mass of the collected insects. You can then count them, and separate by species etc. It's difficult to avoid being sucked in so it's very unlikely that learned avoidance plays any role here; it's simply sampling flying insects in the local vicinity.
