Artificial light quality affects herbivore preference for seedlings

Researchers evaluated the preference of adult sweet potato whitefly to cucumber seedlings grown under fluorescent lamps or metal-halide lamps that provided a spectrum similar to that of natural light. They observed significantly fewer whitefly adults on the fluorescent cucumber treated seedlings than on the metal-halide treated seedlings 24 hours after release. The scientists recommended that growers consider light quality when selecting light sources for transplant production.
