A modified trap for spotted lanternfly egg masses: material innovation and optimization.
Article in Pest management science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe spotted lanternfly, Lycorma delicatula (White) (Hemiptera: Fulgoridae), is a destructive invasive pest that demands effective monitoring and control. Current methods for managing L. delicatula egg masses are insufficient, highlighting the need for tree-safe, efficient trapping solutions. This study developed and optimized a lampshade trap for monitoring, collection, and physical control of L. delicatula egg masses through two phases of field experiments.
resultsIn 2024, a 2-mm thick felt cloth outperformed other black materials, collecting 1790 egg masses from 30 traps. Replacing the fiber batting with a textured, waterproof expanded polyethylene (EPE) foam enhanced the traps' attractiveness and prevented mold growth. In 2025, the effects of color and aperture were tested across 54 traps, resulting in the collection of 3996 egg masses (mean = 74.0 per trap), with the black half-opening design achieving the highest density (148.63 per m
conclusionThe optimized felt cloth trap, with black or brown felt recommended (gray also effective) and aperture type selectable based on field wind conditions, is a cost-effective, practical, and environmentally friendly tool that efficiently concentrates oviposition, significantly enhances egg mass collection rates compared to earlier designs, and is well-suited for integrated L. delicatula management programs. © 2026 Society of Chemical Industry.
