The spread of Aedes albopictus (Diptera: Culicidae) in the islands of São Tome and Príncipe

The mosquito Aedes albopictus (Diptera: Culicidae) is a vector species of the causal agents of Dengue, yellow fever, and Zika among other diseases pathogens. The species originated in Southeast Asia and has spread widely and rapidly in the last century. The species has been reported in localities from the Gulf of Guinea since the early 2000s, but systematic sampling has been scant. We sampled Ae. albopictus twice, in 2013 and 2023 across the altitudinal gradient in São Tomé and found that the species was present in all sampled years at altitudes up to 680 meters. We also found some evidence of increases in proportional representation compared to Ae. aegypti over time. We report the presence of the species in Príncipe for the first time, suggesting that the range of Ae. albopictus is larger than previously thought. Finally, we use bioclimatic niche modeling to infer the potential range of Ae. albopictus and infer that the species has the potential to spread across a large portion of São ..., , , # The spread of Aedes albopictus (Diptera: Culicidae) in the islands of São Tom and Príncipe.

This submissions contains one dataframe relating altitude and Aedes abundance and the R code to generate linear models to quantify the effect of altitude.

## Description of the data and file structure

The R code contains instructions to execute the linear models that assess the effect of altitude on the abundance of two species Aedes along the altitudinal gradient in São Tomé island.

The only required data for this analysis can be found in: dataframe_aedes_ST_altitude.csv

dataframe_aedes_ST_altitude.csv is a cvs file which contains the data to assess the effect of altitude on the abundance of two species Aedes along the altitudinal gradient in São Tomé island. The data constitutes collections of immature stages and adults of *Aedes* along the altitudinal transect of the island of São Tomé. Larvae were coll...
