Life-history responses of the fall webworm <em>Hyphantria cunea</em> to temperature change: Not following the temperatureâsize rule
收藏资源简介：
Temperature serves as a critical environmental factor for ectotherms and significantly impacts numerous life history traits. This study examined the influence of temperature on life-history traits of the fall webworm Hyphantria cunea at 20, 22, 24, 26 and 28 °C. There were no significant differences in larval survival rates across the temperatures tested. However, pupal survival at 28 °C was significantly lower compared to other temperatures. Sex ratios remained consistent at 20â26 °C but skewed toward males at 28 °C. The developmental time from egg to adult decreased as the temperature rose, with males emerging earlier than females (protandry), primarily due to shorter larval stages. Pupal weight exhibited temperature- and sex-dependent trends: female pupae peaked at 22°C (184.6 mg) and there was a 9.2% increase at 28 °C as compared with 20 °C, demonstrating a&nb..., , # Life-history responses of the fall webworm *Hyphantria cunea* to temperature change: Not following the temperatureâsize rule Dataset DOI: [10.5061/dryad.5qfttdzkk](https://doi.org/10.5061/dryad.5qfttdzkk) ## Description of the data and file structure This study investigates how temperature affects life-history traits of the fall webworm (Hyphantria cunea), an invasive pest moth. We examined development time, survival, body weight, growth rate, sexual size dimorphism (SSD), and fecundity across five constant temperatures (20â28â¯Â°C). Results reveal sex-specific responses to temperature, with females showing a reverse temperatureâsize rule and males exhibiting higher thermal sensitivity. The dataset includes individual-level life-history data and reproductive metrics, supporting findings on protandry, SSD, and fecundity advantages. Two Excel files are supplied: File-1 = individual life-table raw measurements; File-2 = paired reproductive outputs of mated females. All work was cond...,
