Life history and fitness costs in the lambda-cyhalothrin resistant clone of English grain aphid, Sitobion avenae (Fabricius).

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 English grain aphid, Sitobion avenae (Fabricius) (Hemiptera: Aphididae), is a highly detrimental cereal aphid in Western Europe, infesting all cereal crops, including barley, wheat and oats. Pyrethroid pesticides are extensively utilized for the management of S. avenae worldwide. The extended use of pyrethroid pesticides to manage S. avenae has led to the emergence of resistance to lambda-cyhalothrin. However, a detailed assessment of life-history traits linked to lambda-cyhalothrin resistance in S. avenae has not yet been conducted. The objectives of this study were to utilize age-stage, two-sex life table theory to examine the life-history traits of a widespread clonal lineage of S. avenae that exhibits partial resistance to lambda-cyhalothrin.
resultsThere was a significant decrease in the relative fitness (0.508) of lambda-cyhalothrin-resistant clones (SA3) in comparison to the susceptible clonal lineage (SA27) of S. avenae. The biological parameter data indicated that the SA3 clonal lineage exhibited significantly prolonged developmental stages (excluding N4) and reduced longevity, fecundity, adult pre-reproductive period, and reproductive days compared to the SA27 clone. By contrast, population growth parameters, including the net reproduction rate (R
conclusionsThese data provide comprehensive insights into the life-history characteristics and population dynamics of the lambda-cyhalothrin-resistant clone of S. avenae, which may be fundamental for development of decision support tools and resistance management measures against this pest. © 2025 The Author(s).
