There was a similar correlation reported between nightly abundance of Anopheles species with relative humidity (range: 27.00–56.40%) and ambient temperature (range: 29.20 °C–30.00 °C) during the peak biting period ( Asgarian, Moosa-Kazemi & Sedaghat, 2021 ).

“…For example, temperature and wind movement can influence mosquito activity patterns ( Bowen, 1991 ), abundance ( Ram et al, 1998 ; Wu et al, 2007 ), and survival ( Ciota et al, 2014 ). An increase in environmental temperature was associated with increased host seeking activity of Culex pipiens, Aedes detritus and Aedes caspius ( Drakou et al, 2020 ) and Anopheles populations ( Asgarian, Moosa-Kazemi & Sedaghat, 2021 ). Therefore, it accelerated the blood digestion, increased human biting frequency, shortened the gonotrophic cycle of An.…”

Background Whilst the human landing catch (HLC) technique is considered the ‘gold standard’ for estimating human-biting rates, it is labor-intensive and fraught with potential risk of exposure to infectious mosquito bites. This study evaluated the feasibility and performance of an alternative method, the human double net trap (HDNT) relative to HLC for monitoring host-seeking malaria vectors of the Anopheles minimus complex in a semi-field system (SFS). Methods HDNT and HLC were positioned in two rooms, 30 m apart at both ends of the SFS. Two human volunteers were rotated between both traps and collected released mosquitoes (n = 100) from 6:00 pm till 6:00 am. Differences in Anopheles mosquito densities among the trapping methods were compared using a generalized linear model based on a negative binomial distribution. Results There were 82.80% (2,136/2,580) of recaptures of wild-caught and 94.50% (2,835/3,000) of laboratory-reared mosquitoes that were molecularly identified as An. harrisoni and An. minimus, respectively. Mean density of An. harrisoni was significantly lower in HNDT (15.50 per night, 95% CI [12.48–18.52]) relative to HLC (25.32 per night (95% CI [22.28–28.36]), p < 0.001). Similarly, the mean density of a laboratory strain of An. minimus recaptured in HDNT was significantly lower (37.87 per night, 95% CI [34.62–41.11]) relative to HLC (56.40 per night, 95% CI [55.37–57.43]), p < 0.001. Relative sampling efficiency analysis showed that HLC was the more efficient trap in collecting the An. minimus complex in the SFS. Conclusion HDNT caught proportionately fewer An. minimus complex than HLC. HDNT was not sensitive nor significantly correlated with HLC, suggesting that it is not an alternative method to HLC.

“…The Intergovernmental Panel on Climate Change (IPPC, 2018) has indicated that mosquito-borne diseases (MBDs) will be particularly impacted by climate change. Indeed, seasonal variations in the occurrence and abundance of mosquito populations are intricately tied to climatic factors, which in turn impact their vector potential [ 3 ]. In Canada, the burden of MBDs has increased by 10% in the past 20 years and is expected to continue to rise if the impacts of climate change are not mitigated [ 4 ].…”

“…Precipitation can alter the occurrence of suitable larval habitats [ 22 , 24 , 25 ] and the viability of eggs and larvae [ 26 ]. Humidity can affect the mating, dispersal, longevity, bloodfeeding behaviors, and oviposition of mosquitoes [ 3 , 27 , 28 ]. However, there are numerous mitigating factors that can drastically alter mosquito population dynamics (e.g., forest cover), and the combined effects of multiple abiotic and biotic factors are often challenging to resolve.…”

The influence of weather on the population dynamics of common mosquito vector species in the Canadian Prairies

Background Mosquito seasonal activity is largely driven by weather conditions, most notably temperature, precipitation, and relative humidity. The extent by which these weather variables influence activity is intertwined with the animal’s biology and may differ by species. For mosquito vectors, changes in weather can also alter host–pathogen interactions thereby increasing or decreasing the burden of disease. Methods In this study, we performed weekly mosquito surveillance throughout the active season over a 2-year period in Manitoba, Canada. We then used Generalized Linear Mixed Models (GLMMs) to explore the relationships between weather variables over the preceding 2 weeks and mosquito trap counts for four of the most prevalent vector species in this region: Oc. dorsalis, Ae. vexans, Cx. tarsalis, and Cq. perturbans. Results More than 265,000 mosquitoes were collected from 17 sampling sites throughout Manitoba in 2020 and 2021, with Ae. vexans the most commonly collected species followed by Cx. tarsalis. Aedes vexans favored high humidity, intermediate degree days, and low precipitation. Coquillettidia perturbans and Oc. dorsalis activity increased with high humidity and high rainfall, respectively. Culex tarsalis favored high degree days, with the relationship between number of mosquitoes captured and precipitation showing contrasting patterns between years. Minimum trapping temperature only impacted Ae. vexans and Cq. perturbans trap counts. Conclusions The activity of all four mosquito vectors was affected by weather conditions recorded in the 2 weeks prior to trapping, with each species favoring different conditions. Although some research has been done to explore the relationships between temperature/precipitation and Cx. tarsalis in the Canadian Prairies, to our knowledge this is the first study to investigate other commonly found vector species in this region. Overall, this study highlights how varying weather conditions can impact mosquito activity and in turn species-specific vector potential. Graphical Abstract

“…In dry atmospheric conditions, mosquitoes desiccate easily resulting in depletion of adult vectors. A relative humidity of at least 50 to 60% ensures prolonged mosquito survival and breeding sites for the mosquitoes to lay eggs (Asgarian et al, 2021). Furthermore climatic variables alter interactions among the mosquito species and subsequently result in an increase or decrease of their population in particular areas (Weicheld, 2015).…”

The present investigation was an attempt to find out the mosquito fauna diversity and distribution in relation with meteorological factors across three study localities/sites of Baramulla district (Kashmir division), India. The study period between May to October of 2019 and 2020, encountered a total of 701 mosquito specimens with maximum number of individuals recorded from Sopore (n=250) followed by Rafiabad (n=242) and Zaingeer (n=209). The mosquitoes seasonally reported were mostly found abundantly in summer (n=418). Monthly collections illustrated that number of mosquitoes were recorded maximum in August and September (n=381) and minimum in May and June (n=76). Culex quinquefaciatus was abundantly encountered and represent the highest percentage occurrence of 38.088% whereas Anopheles gigas contributed a minimum percentage occurrence of 5.563% among all species reported during the study period. In August 2019, maximum temperature and humidity recorded was 29.6 C/87% and minimum temperature and humidity was 17.5 C/66%. Precipitation observed was 155.5 mm. The maximum temperature and humidity observed during August, 2020 was 31.2 C/85% and minimum temperature and humidity was 18.6 C/69%. Overall study period suggested that maximum temperature and relative humidity supported the prevalence of mosquitoes. The precipitation recorded was 153.2 mm. In May 2019 and May, 2020, the rainfall observed was 150.9 mm and 138.0 mm, respectively, but the fluctuation in temperature and humidity does not favour the mosquito growth, thereby least density was observed. In other words, the requirement of an ideal temperature, rainfall and humidity is an essential variable for survival of mosquitoes in aquatic habitats.
