Behavioural manipulation of the cabbage stem flea beetle (Psylliodes chrysocephala L): Prospects for push-pull strategies in oilseed rape.
Review 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
The cabbage stem flea beetle (CSFB, Psylliodes chrysocephala L) is a major pest of oilseed rape (OSR, Brassica napus L), especially in temperate regions where it is challenging the sustainable production of the crop. Conventional management has relied almost exclusively on synthetic insecticides, yet increasing regulatory restrictions, pest resistance and environmental concerns require the urgent development of alternative strategies. Semiochemicals, chemical cues that mediate inter- and intraspecific behavioural interactions, offer considerable potential for integration into push-pull pest management programmes, where combinations of attractant and deterrent or repellent stimuli are used synergistically to reduce crop pest infestation. This review synthesises knowledge of olfaction in CSFB and their behavioural responses to plant-derived and other bioactive compounds, as well as to synthetic analogues that attract or repel the pest. Glucosinolates, which are non-volatile, and their volatile derivatives, isothiocyanates, have been shown to act as phagostimulants and attractants, respectively. Furthermore, companion planting with attractive host plant 'trap crops' has potential to suppress and divert pest pressure from the main OSR crop. By contrast, companion planting with non-host plant species, as well as the application of plant solvent extracts and plant-derived hormones, has been demonstrated to repel, deter and/or induce antifeedant effects in CSFB, respectively. Although these approaches show great promise, significant knowledge gaps remain regarding the identity of the chemicals involved, dose-dependent behavioural responses, and the interplay between visual, olfactory and tactile cues in CSFB host selection, feeding and oviposition behaviours. Addressing these gaps could inform the design and development of targeted semiochemical-based interventions that are effective, environmentally benign and compatible with integrated pest management. © 2026 The Author(s).
