title: Data from: Differential responses of sexual and asexual <em>Aphis gossypii</em> lineages to climate change: shifts in distribution, phenology, and host-plant interactions

description: This dataset integrates multi-source data for analyzing the distribution
 patterns of sexual and asexual lineages of the cotton aphid, Aphis
 gossypii. The core component comprises simulated Ecoclimatic Indices (EI)
 and Growth Indices (GI) generated using the CLIMEX model (Version 4.0.2,
 Hearne Scientific Software) for both a historical baseline period (1995)
 and a future climate scenario (2100). The model was calibrated through an
 iterative process, culminating in the use of 22 parameters for the sexual
 lineage and 17 parameters for the asexual lineage to achieve an optimal
 fit between the projected and documented species distributions. To support
 model validation and parameterization, the dataset incorporates two
 auxiliary data components: Firstly, geographical data on the overwintering
 areas of A. gossypii in China, coupled with multi-decadal field-collected
 egg count data (presented as mean ± standard error). This validation data
 spans key regions in China, including Henan, Hebei, Jiangsu, Hubei,
 Shaanxi, and Xinjiang, with records ranging from 1956 to 2019. Secondly,
 georeferenced occurrence data for the primary host plants of the sexual
 lineage of A. gossypii. These data were sourced from the Global
 Biodiversity Information Facility (GBIF) and were spatially rarefied using
 the Spatially Rarefy Occurrence Data tool in ArcGIS to minimize spatial
 autocorrelation. This process resulted in a final set of 120 spatially
 independent points that accurately represent the geographic range and
 climatic zones of the recorded occurrences.
