“…S2) is shown to expand further, and it does not suggest that the future environment is any less suitable for the vector than it is now. This concurs to some extent with the findings of other authors who have projected the Aedes distributions into the future ( Kraemer et al, 2019 , Trájer, 2021 #457; Liu-Helmersson et al, 2019 ).…”

With the increasing distribution range of the vectors worldwide as well as in Nepal and the HKH region in particular (9,19,20) also the spread of VBDs will increase (worldwide: e.g. dengue: (6); Nepal: (86)), underlining that parts of biodiversity can be detrimental to human health.…”

“…For Ae. aegypti it has already been documented that populations can invade novel habitats by following their climate niches as a consequence of global warming (11, 18), moreover their expansion to new regions in the future is likely (19, 20). Further expansion to cooler ecoregions such as Europe will additionally require the adaptation to cooler temperatures (21, 22).…”

BackgroundDriven by globalization, urbanization and climate change, the distribution range of invasive vector species has expanded to previously colder ecoregions. To reduce health-threatening impacts on humans, insect vectors are extensively studied. Population genomics can reveal the genomic basis of adaptation and help to identify emerging trends of vector expansion.ResultsBy applying whole genome analyses and genotype-environment associations to populations of the main dengue vector Ae. aegypti, sampled along an altitudinal temperature gradient in Nepal (200- 1300m), we identify adaptive traits and describe the species’ genomic footprint of climate adaptation to colder ecoregions. We found two clusters of differentiation with significantly different allele frequencies in genes associated to climate adaptation between the highland population (1300m) and all other lowland populations (≤ 800 m). We revealed non-synonymous mutations in 13 of the candidate genes associated to either altitude, precipitation or cold tolerance and identified an isolation-by-environment differentiation pattern.ConclusionOther than the expected gradual differentiation along the altitudinal gradient, our results reveal a distinct genomic differentiation of the highland population. This finding either indicates a differential invasion history to Nepal or local high-altitude adaptation explaining the population’s phenotypic cold tolerance. In any case, this highland population can be assumed to carry pre-adapted alleles relevant for the species’ invasion into colder ecoregions worldwide that way expanding their climate niche.

BACKGROUNDEvaporation inhibition of water‐based space spray insecticides is necessary to prevent the drifting away of fog droplets and the release of insecticidal actives and to prolong suspension time. To address this problem, hygroscopic alcohols, namely propylene glycol and glycerol, were included as adjuvants in water‐based d‐phenothrin formulations. The performances of glycerol‐added formulation (D1) and propylene glycol‐added formulation (D2) in terms of droplet size and efficacy against larvae, pupae and adult Aedes aegypti in an open‐field environment were examined and compared to the performance of a formulation without adjuvant (negative control).RESULTSNo significant difference in droplet size was observed between the formulations and fogging methods. The efficacy of cold fogs was significantly higher than thermal fogs for all formulations. D2 was found to be most effective against adult Ae. aegypti, followed by D1 and the negative control. D1 and D2 provided complete knockdown and mortality in adult Ae. aegypti at 10 and 25 m for cold and thermal fogging, respectively. However, all d‐phenothrin formulations possessed minimal efficacy on immature Ae. aegypti.CONCLUSIONThe incorporation of non‐toxic alcohols as adjuvants in water‐based space spray insecticides increased efficacy against adult Ae. aegypti, a major vector for dengue. Propylene glycol was discovered to induce higher adulticidal efficacy than glycerol. © 2023 Society of Chemical Industry.
