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

Population size and sex ratio are fundamental components of the social environment. Tetranychus urticae Koch (Acari: Tetranychidae) is a globally significant invasive pest, infesting a wide range of economically important agricultural crops. Understanding how population size and sex ratio affect individual fitness and population growth of T. urticae provides crucial insight into population dynamics and management. Here, we tested the influence of population size and sex ratio on reproduction, longevity, and life table parameters in T. urticae. We set up a factorial design with three population sizes and three sex ratios yielding nine combination treatments. Results showed that females in larger populations had greater fecundity and longer lives; however, sex ratio had no significant effect on female fecundity and longevity. In addition, females in larger population sizes had a higher net reproductive rate, a higher intrinsic rate of natural increase, and a shorter population doubling time, suggesting that control strategies should focus on proactive treatments to keep population sizes small to suppress population growth. Offspring survival rate was positively affected by parental population size but negatively affected by offspring population density. In contrast to females, males in larger and male-biased populations had significantly shorter longevity. The findings from this study advance our understanding of how population size and sex ratio shape spider mite life history traits and population dynamics, offering insights for population management.
