Optimized use of UV-B light to suppress Western flower thrips in controlled environment tomato crops.
Article in Pest management science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLEDs (light emitting diodes) are being deployed in controlled environment crop production systems to boost crop growth, manipulate pest behavior, improve performance of natural enemies, and directly suppress pest populations. In this study, seven UV-B (280-315 nm) LED treatments were applied to tomato plants (Solanum lycopersicum L.) (in hours): 1 = 0, 2 = 0.5, 3 = 1, 4 = 2, 5 = 4, 6 = 8, and 7 = 24. Hyperspectral imaging data were acquired and examined based on spectral indices. After initial evaluations, we focused on effects of 4 h exposure to UV-B on oviposition preference and egg hatching by Western flower thrips (WFT) [Frankliniella occidentalis (Pergande)].
resultsExposure to UV-B for 4 h elicited an optimal combination of bio-responses: (1) based on vegetation indices, tomato plants appeared to recover from initial UV-B induced stress, (2) preference bioassays showed tomato plants were preferred by ovipositing WFTs over untreated control plants, and (3) 4 h exposure to UV-B significantly suppressed hatching rates of WFT eggs laid in tomato plants, irrespectively of whether deployed at night or during the day and irrespectively of whether projected from top (to adaxial sides of leaves) or bottom (to abaxial sides of leaves).
conclusionFrom a comprehensive combination of plant and pest experiments, our results provide strong support for claims about 4 h exposure to UV-B possessing considerable potential as a pest management tactic. Results from this study support claims that pest management practices in controlled environment production systems may be more effective when deployed at night. This study is part of ongoing efforts to promote integration of innovative technologies to maximize both performance and sustainability of pest management strategies of vegetable and ornamental crops in controlled environments. © 2025 The Author(s).
