Just stumbled across the following article:
Below I have extracted what I believe to be the most relevant points related to the question asked.
Field vacuuming is a novel concept for pest management in organic cropping systems. Though heavily promoted, it has not been widely adopted.
Field Vacuums for Insect Pest Management
Among the tools that have drawn interest are field vacuums, which suck pests from the growing crop and "batter" them to death.
Growers and researchers have experimented with suction devices on a number of horticultural crops, including lettuce, strawberries, artichokes, grapes, potatoes, celery, and cole crops. The most successful application of insect vacuums appears to be control of lygus bugs in strawberries.
Sometimes, the vacuums simply weren’t adequate for the job. When they tried them for aphid control on lettuce, California growers found that the pest hid mostly in the lower parts of the plant and escaped - a particularly serious problem because the aphids vector several serious diseases
Sources for Insect Vacuums
The California supplier BioQuip Products has several small vacuums that are mostly intended for insect monitoring and collecting, rather than control. One of the vacuums is a backpack unit, however, which might be useful for pest control in biointensive systems.
For very small-scale applications, the "Bug Vacuum" - a battery-operated, hand-held unit may work. However, it appears designed primarily for removing individual insects like errant wasps, bees, and flies from the home.
Field vacuums are an interesting non-chemical approach to insect pest management. While promising, the concept has not received wide use because of a number of problems, including cost and efficacy.
