1 · What the graph read from it

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.

2 · The registry

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

backgroundFalse codling moth (FCM) is a polyphagous Tortricid moth that is a priority agricultural pest. Mating disruption shows potential as an environmentally friendly and sustainable control option against FCM in stone fruit, table grapes and citrus. How the technique alters the mate-finding ability of FCM and what factors are important to ensure the control success is uncertain. Recent work indicated that Lepidoptera are disrupted either competitively or non-competitively. No studies have yet been conducted on FCM to determine its disruptive mechanism. However, studies conducted on closely related species have proposed and critically evaluated a framework, along with a dichotomous key, for distinguishing between the two mechanisms.

resultsA protocol for identifying the underlying disruption mechanism in other species is provided. Here the dosage-response profile, the optimal dosage and optimal density were calculated from multiple mark-release-recapture (MRR) experiments, using sterile FCM. Stone fruit and table grape blocks were treated with increasing levels of pheromone dispenser densities, which allowed the level of disruption experienced (FCM caught in treated/untreated blocks) to be calculated. While mating disruption proved highly effective in stone fruit and table grapes against FCM, the FCM followed a hybrid disruption profile and were disrupted competitively at low dosages and non-competitively at higher dosages.

conclusionThe shift to non-competitive disruption, which resulted in 99% disruption, was achieved at a dosage of 800 dispensers/ha uniformly distributed and remained effective with as few as 36 pheromone release sites per ha. Mating disruption is, therefore, highly recommended to form part of the current integrated pest management program for FCM. © 2025 The Author(s).
