FYI, we have a really good albopictus-CHIKV/DENV model that can predict outbreaks accurately (papers in review/prep), if of interest. At least, they work well in Europe.

Yes, but nowhere near to the same severity. Something like ~32 autochthonous cases <2024 and ~729 autochthonous cases in 2025 so far!!

Moving into Oct with temperatures & daylight hours falling in Scotland, the "peak" mosquito activity season is passing. However, some species like Culex pipiens can still be found 'overwintering'; like this one our team found on #Arran yesterday. Let us know if you see any

We show that control strategies can be highly effective in reducing dengue cases. However, extreme precipitation events may have also had a large contribution to reducing the number of cases for one of the outbreaks.

Role of vector phenotypic plasticity in disease transmission as illustrated by the spread of dengue virus by Aedes albopictus - Nature Communications There is a need for accurate models to predict disease dynamics by considering the interactions between environment and vector traits. This study finds that incorporating delayed phenotypic plasticity in mosquito traits significantly enhances the accuracy of dengue risk predictions.

Using out state-of-the-art Aedes albopictus-dengue model (www.nature.com/articles/s41...), we predict the control efficacy for two recent large Italian dengue outbreaks.

Hot days and light-polluted nights increase nighttime activity of the diurnal tiger mosquito (Aedes albopictus) - BMC Environmental Science Background Global urbanization and climate change introduce significant environmental challenges such as light pollution (a.k.a., artificial light at night or ALAN) and rising temperatures. Both factors have the potential to disrupt the temporal activity patterns of many species, including key disease vectors such as the tiger mosquito (Aedes albopictus). This study aimed to investigate whether light pollution and elevated daytime temperatures prompt Ae. albopictus to shift their activity towards the night, a typically less active period for these day-active mosquitoes. Methods During the summer of 2023, we enrolled 58 households across the Greater St. Louis area (MO, USA) and used traps to collect and monitor the host-seeking and mate-seeking activity of the tiger mosquito. Sites were selected across a light pollution gradient, and temperature was measured using field loggers and extracted from local weather stations. We analyzed the relationship between light pollution and daytime temperature with nighttime mosquito abundance using generalized additive models (GAMs) with negative binomial distributions, including percent impervious surface as a covariate. Results We found a pronounced increase in mosquito activity at night at sites with high levels of light pollution. Percent impervious surface only explained a small portion of the variance in nighttime abundance, while both daytime mosquito abundance and the interaction between light pollution and temperature explained substantial portions of the variance in nighttime abundance. The significant interaction between light pollution and temperature indicates that the effect of light pollution on nighttime mosquito activity strongly depends on temperature. Specifically, nighttime mosquito abundance was low at lower levels of light pollution but increased significantly starting around 3500 ¡cd m⁻², but only when daytime temperatures approached or exceeded the critical thermal maximum of females. Conclusions Our findings suggest that rising temperatures and light pollution can extend the temporal activity period of Ae. albopictus. This adjustment in activity could buffer Ae. albopictus against rising temperatures, create novel nighttime vector-host encounters, and inform vector control strategies within urban environments. Clinical trial number Not applicable.

A study in BMC Environmental Science finds that rising temperatures and light pollution at night may cause the tiger mosquito (Aedes albopictus) to become more active, creating new risks for disease transmission in urban areas.

It's not about immigrantation. In France, for example, it's mainly due to travel between mainland France and some particular overseas territories.

I think that the title is slightly misleading, at least in the case of CHIKV. Here, it's more to do with large numbers of imported cases from source locations spawning local outbreaks in Europe.
