Climate Change Can Generate Enemy-Free Space for Crop-Feeding Herbivores.
Article in Global change biology, 2026. 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
Crop-feeding herbivores reduce the world's food output by approximately 20% and climate change (CC) is bound to deepen those losses. Endemic or introduced consumer organisms (i.e., biological control agents) naturally regulate herbivore populations and secure a quarter of crop yields, but are exceptionally susceptible to CC-related disturbances. Here, we use niche modeling for 14 globally-important herbivores (or pests) to forecast how richness of the associated biological control agents of each pest-as a proxy of service strength-may alter under a CC-driven range expansion. Results show that 57%-100% of pests are bound to lose parasitoid and predator associates. The cassava mealybug Phenacoccus manihoti may experience a 27% decline in parasitoid pressure, whereas cosmopolitan pests of cereal and horticultural crops benefit from 6% to 7% drops in predator pressure. Such 'enemy release' can possibly exacerbate pest-induced yield losses and threaten future harvests. Ant-pest associations change in both directions, implying that pests may either face strengthened or weakened biological control. For pests spreading towards or within food-deficit regions in the equatorial belt, parasitoid declines and increases in ant pressure are most pronounced. By exposing the fragility of biodiversity-based ecological safeguards in farmland, our work calls for urgent, integrative, and nature-friendly solutions to uphold food security under environmental change.
