Assessing The Potential Distributions Of The Invasive Mosquito Vector Aedes Albopictus And Its Natural Wolbachia Infections In Mexico

Simple SummaryThis study updated the potential distribution of the Asian tiger mosquito Aedes albopictus in Mexico and provided estimates to model uncertainty. We also assessed the potential distribution of natural Wolbachia infections in Ae. albopictus in Mexico to map areas with circulation potential of Wolbachia. The distribution of Ae. albopictus covered the states across Northern Mexico, the Gulf of Mexico, the Pacific Coast of Mexico, Central Mexico, and the southeast of Mexico. The ecological niche model of the Wolbachia infections anticipated its occurrence in the southeast of Mexico, the Chiapas border with Guatemala, and Veracruz. While these results can prioritize vector surveillance and control programs for decision-makers, it is still necessary to establish active surveillance programs to validate the ecological niche of natural Wolbachia infections in Ae. albopictus populations in Mexico.The Asian tiger mosquito Aedes albopictus is currently the most invasive vector species, with a widespread global distribution. Aedes albopictus is the potential vector of diverse arboviruses, including Zika and dengue. This study updated the ecological niche model of Ae. albopictus and inferred the potential distribution of natural Wolbachia infections in Ae. albopictus in Mexico. The ecological niche models were constructed based on diverse model settings to better estimate the potential distributions and uncertainty indices of both Ae. albopictus and its natural Wolbachia infections in Mexico. The distribution of Ae. albopictus covered the states across Northern Mexico, the Gulf of Mexico, the Pacific Coast of Mexico, Central Mexico, and the southeast of Mexico. The ecological niche model of the natural Wolbachia infections in Ae. albopictus populations anticipated the occurrence of natural Wolbachia infections in the southeast of Mexico, the Chiapas border with Guatemala, and Veracruz. These results can be used to prioritize vector surveillance and control programs in Mexico for strategic and future decision-making; however, it is still necessary to establish active surveillance programs to assess model predictions based on the independent sampling of Ae. albopictus from different invasion zones in Mexico. Finally, vector surveillance should also screen the natural Wolbachia infections in Ae. albopictus to validate Wolbachia predictions across Mexico, particularly in the southeast of Mexico.
