I assume the cucumbers under screening must be parthenocarpic such that
lack of pollination would not be a problem. Any recommended
variety/source? -Olin

I would imagine that the screening is under the plants and off the soil.

No, the screening is over the plants to keep off cucumber beetles (which carry
the wilt). I plant parthenocarpic varieties, which do not need pollination.
