Raw data for <b>Variation in Cold Tolerance Among Iranian Populations of </b><b><i>Orius albidipennis</i></b><b> (Hemiptera: Anthocoridae)</b>.xlsx

This dataset contains the raw data supporting the publication entitled “Variation in Cold Tolerance Among Iranian Populations of Orius albidipennis (Hemiptera: Anthocoridae).” The study aimed to evaluate inter-population variation in cold tolerance among seven geographically distinct Iranian populations of O. albidipennis, an important biological control agent. The dataset includes experimental results of adult survival under cold storage at three temperatures (4, 7, and 10 °C). Bugs were collected from Gorgan, Mashhad, Yazd, Shiraz, Karaj, Varamin, and Shahrud, reared for five laboratory generations, and subjected to controlled cold tolerance assays. Data records comprise mortality counts over time, along with associated variables: population source, storage temperature, storage density (individual, 10, 20, or 30 per container), body size category (small/large), and sex. Each record also includes details of acclimation prior to cold exposure as well as experimental replicate information. These data can be used to analyze survival patterns, estimate LT50 values, and assess the effects of body size, sex, storage density, and origin climate on cold tolerance in O. albidipennis. The dataset facilitates further meta-analyses in insect thermal biology, supports the development of improved cold-storage protocols for augmentative biological control, and allows reproducibility and statistical validation of the published results. A README file describing variable definitions, experimental conditions, and file structure is included.
