“…The impact of temperature and humidity on the life-history, physiology, behaviour and ecology of Ae. aegypti has been extensively investigated under laboratory conditions [108][109][110][111][112][113][114][115][116] [99]. Such variability seems to be common and related to optimal humidity and temperature conditions available during such hours [117,118].…”

BackgroundEntomological monitoring of Aedes vectors has largely relied on surveillance of larvae, pupae and non-host-seeking adults, which have been poorly correlated with human disease incidence. Exposure to mosquito-borne diseases can be more directly estimated using Human Landing Catches (HLC), although this method is not recommended for Aedes-borne arboviruses.We evaluated a new method previously tested with malaria vectors, the Mosquito Electrocuting Trap (MET) as an exposure-free alternative for measuring landing rates of Aedes mosquitoes on people. Aims were to 1) compare the MET to the BG-sentinel (BGS) trap gold standard approach for sampling host-seeking Aedes vectors; 2) characterize the diel activity of Aedes vectors and their association with microclimatic conditions. MethodsThe study was conducted over 12 days in Quinindé -Ecuador in May 2017. Mosquito sampling stations were set up in the peridomestic area of four houses. On each day of sampling, each house was allocated either a MET or a BGS trap, which were rotated amongst the four houses daily in a Latin square design. Mosquito abundance and microclimatic conditions were recorded hourly at each sampling station between 07:00-19:00 hours to assess variation between vector abundance, trapping methods, and environmental conditions. All Aedes aegypti females were tested for the presence of Zika (ZIKV), dengue (DENV) and chikungunya (CHIKV) viruses.3 ResultsA higher number of Ae. aegypti females were found in MET than in BGS collections, although no statistically significant differences in mean Ae. aegypti abundance between trapping methods were found. Both trapping methods indicated female Ae. aegypti had bimodal patterns of host seeking, being highest during early morning and late afternoon hours. Mean Ae. aegypti daily abundance was negatively associated with daily temperature. No infection by ZIKV, DENV or CHIKV was detected in any Aedes mosquitoes caught by either trapping method. ConclusionWe conclude the MET performs at least as well as the BGS standard, and offers the additional advantage of direct measurement of per capita human biting rates. If detection of arboviruses can be confirmed in MET-collected Aedes in future studies, this surveillance method could provide a valuable tool for surveillance and prediction on human arboviral exposure risk. BACKGROUNDMosquito--borne viruses (arboviruses) are an important cause of diseases in humans and animals. In 2017, estimates suggested that mosquitoes were responsible for approximately 137 millions human arboviral infections with dengue (DENV), chikungunya (CHIKV), and Zika virus (ZIKV) being the most important [1]. Arbovirus transmission to humans depends on multiple factors that involve spatial movement and immunity of human populations [2-7], socioeconomic factors and access to basic services (especially water) [8][9][10][11], and the ecology and distribution of the mosquito vectors that transmit them [12][13][14][15][16][17][18][19]. These factors combine to determine the distribution and intens...

16In recent years, Zika spread through the Americas. This virus has been linked to 17 Guillain-Barré syndrome, which can lead to paralysis, and microcephaly, a severe birth 18 defect. Zika is primarily transmitted by Aedes (Ae.) aegypti, a mosquito whose geographic 19 range has expanded and is anticipated to continue shifting as the climate changes. 20 We used statistical models to predict regional suitability for autochthonous Zika 21 transmission using climatic variables. By suitability for Zika, we mean the potential for an 22 outbreak to occur based on the climate's habitability for Ae. aegypti. We trained zero-2 23 inflated Poisson (ZIP) and zero-inflated negative binomial (ZINB) regression models to 24 predict Zika outbreak suitability using 20 subsets of climate variables for 102 regions. 25 Variable subsets were selected for the final models based on importance to Ae. aegypti 26 survival and their performance in aiding prediction of Zika-suitable regions. We 27 determined the two best models to both be ZINB models. The best model's regressors 28 were winter mean temperature, yearly minimum temperature, and population, and the 29 second-best model's regressors were winter mean temperature and population. 30 These two models were then run on bias-corrected climate projections to predict 31 future climate suitability for Zika, and they generated reasonable predictions. The 32 predictions find that most of the sampled regions are expected to become more suitable 33 for Zika outbreaks. The regions with the greatest risk have increasingly mild winters and 34 high human populations. These predictions are based on the most extreme scenario for 35 climate change, which we are currently on track for. 36 37 Author Summary: 38 In recent years, Zika spread through the Americas. This virus has been linked to 39 Guillain-Barré syndrome, which can lead to paralysis, and microcephaly, a severe birth 40 defect. Zika is primarily transmitted by Aedes (Ae.) aegypti, a mosquito whose geographic 41 range has expanded and is anticipated to continue shifting as the climate changes. We 42 used statistical models to predict regional suitability for locally-acquired Zika cases using 43 climatic variables. By suitability for Zika, we mean the potential for an outbreak to occur 44 based on the climate's habitability for Ae. aegypti. We trained statistical models to predict 45 Zika outbreak suitability using 20 subsets of climate variables for 102 regions. Variable 3 46 subsets were selected for the final two models based on importance to Ae. aegypti 47 survival and their performance in aiding prediction of Zika-suitable regions. These two 48 models were then run on climate projections to predict future climate suitability for Zika, 49 and they generated reasonable predictions. The predictions find that most of the sampled 50 regions are expected to become more suitable for Zika outbreaks. The regions with the 51 greatest risk have high human populations and increasingly mild winters. 52 53
