Susceptibility of Phthorimaea absoluta (Meyrick) (Lepidoptera: Gelechiidae) to novel and established insecticides in Brazil: resistance survey, baseline, and implications for management.

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
backgroundPhthorimaea (=Tuta) absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a major tomato pest worldwide, and its management is increasingly threatened by rapid resistance evolution. The recent introduction of isocycloseram and tolfenpyrad-two insecticides with novel modes of action-offers new control options, but their sustainability depends on establishing susceptibility baselines and enabling early resistance detection.

conclusionP. absoluta populations are susceptible to isocycloseram and tolfenpyrad, but early tolerance shifts signal emerging adaptive responses that merit close monitoring. The enzymatic associations observed highlight the central role of metabolic detoxification in shaping susceptibility and potential cross-resistance. Overall, the new chemistries remain useful options for P. absoluta control, but their long-term effectiveness depends on early identification of susceptibility shifts and incorporating metabolic insights into resistance management strategies. © 2026 The Author(s).
