“…Wilke et al [86] examined determinants of Aedes aegypti, Aedes albopictus, Aedes fluviatilis, Aedes scapularis, Culex nigripalpus and Culex quinquefasciatus dynamics in urban parks in São Paulo, Brazil. They reported on the impact of urban development as well as monthly temperature and accumulated rainfall over the month of collection and the previous month on species richness and abundance in that context [86]. They found temperature to significantly impact species abundance, but that correlation differed by species [86].…”

27 Background 28 Three arthorpod-borne viruses (arboviruses) causing human disease have been the focus 29 of a large number of studies in the Americas since 2013 due to their global spread and 30 epidemiological impacts: Zika, dengue, and chikungunya viruses. A large proportion of 31 infections by these viruses are asymptomatic. However, all three viruses are associated with 32 moderate to severe health consequences in a small proportion of cases. Two mosquito species, 33 Aedes aegypti and Aedes albopictus, are among the world's most prominent arboviral vectors, 34 and are known primary vectors for all three viruses in the Americas. 35 Objectives 2 36 This review summarizes the state of the entomological literature surrounding the biology 37 and ecology of vectors of Zika, dengue and chikungunya viruses and factors affecting virus 38 transmission. The rationale of the review was to elucidate consensus and discord between 39 studies, and guide future research based on identified knowledge gaps. 40 Results 41 A total of 196 studies were included in the scoping review after initial screening and 42 subsequent exclusion of out-of-scope studies, secondary data publications, duplicate records, and 43 studies unavailable in English language. 44 Key findings 45 Temperature and humidity have the strongest impact on mosquito distribution and 46 dynamics, development of immatures and arborviral infection rates. Low socioeconomic status 47 and related factors, including poor infrastructure, inconsistent access to water, and high 48 household resident density, have been consistently associated with arbovirus vector occurrence. 49 Effects of interspecific competition on arboviral vector species is currently poorly understood. 50 Vector competence for Zika virus is well established for Ae. aegypti and Ae. albopictus. 51 Information on Zika virus vector transmission dynamics is sparse in contrast to the wealth of 52 research available for dengue and chikungunya viruses. 53 Conclusions 54Based on the internationally recognized urgency of Zika virus infection as a public health 55 concern, further research on arbovirus vectors and transmission dynamics is of pressing need. 56 57

“…Although Cx. pipiens population dynamics are known to be regulated by both density-dependent and climatic and environmental factors [23,47,48], the complexity of its ecology hampers the capacity to assess univocally to what extent the key drivers regulate the population dynamics. The great variability observed in both the number and distribution of WNV cases in Italy over the years, laid the basis for speculating that year to year variations in environmental and climatic factors, and their combinations, could induce diverse responses in mosquito dynamics, ultimately affecting the pattern of occurrence of WNV cases.…”

Background: Vector-borne infectious diseases (VBDs) represent a major public health concern worldwide. Among VBDs, West Nile Virus (WNV) showed an increasingly wider spread in temperate regions of Europe, including Italy. During the last decade, WNV outbreaks have been recurrently reported in mosquitoes, horses, wild birds, and humans, showing great variability in the temporal and spatial distribution pattern. Due to the complexity of the environment-host-vector-pathogen interaction and the incomplete understanding of the epidemiological pattern of the disease, WNV occurrences can be hardly predictable. The analyses of ecological drivers responsible for the earlier WNV reactivation and transmission are pivotal; in particular, variations in the vector population dynamics may represent a key point of the recent success of WNV and, more in general, of the VBDs. Methods: We investigated the variations of Culex pipiens population abundance using environmental, climatic and trapping data obtained over nine years (2010 to 2018) through the WNV entomological surveillance program implemented in northeastern Italy. An Information Theoretic approach (IT-AIC c ) and model-averaging algorithms were implemented to examine the relationship between the seasonal mosquito growth rates and both intrinsic (e.g. intraspecific competition) and extrinsic (e.g. environmental and climatic variables) predictors, to identify the most significant combinations of variables outlining the Cx. pipiens population dynamics. Results: Population density (proxy for intraspecific competition) and length of daylight were the predominant factors regulating the mosquito population dynamics; however, also other drivers encompassing environmental and climatic variables had a significant impact, although sometimes counterintuitive and not univocal. The analyses of the single-year datasets, and the comparison with the results obtained from the overall model (all data available from 2010 to 2018), highlighted remarkable differences in coefficients magnitude, sign, and significance. These outcomes indicate that different combinations of factors might have distinctive, and sometimes divergent, effects on mosquito population dynamics.Conclusions: A more realistic acquaintance of the intrinsic and extrinsic mechanism of mosquito population fluctuations in relation to continuous changes in environmental and climatic conditions is DMI: De Martonne

BACKGROUND: Mosquitoes are hematophagous insects of major public health concern, serving as vectors of many diseases. Available products for personal protection against mosquitoes lack adequate efficacy and in most cases need to be reapplied or replaced frequently. In recent years, the encapsulation of the active repellents in various matrices has arisen as an alternative method for the development of new-generation repellent systems. The aim of the present study was to explore the potential of functional micro/nanofibrous matrices as systems for the sustained release of the highly volatile insect-repellent citronella oil. RESULTS: Micro/nanofibrous single-and triple-layer systems incorporating citronella oil as the active agent were developed via the electrospinning technique using the low-cost, non-toxic, biodegradable polymers cellulose acetate and polyvinylpyrrolidone. All the micro/nanofiber systems produced exhibited prolonged release of citronella oil and a high repellent activity in laboratory bioassays against the mosquito Aedes albopictus for at least 4 weeks. CONCLUSION: Considering the high volatility of the embedded repellent, the present study demonstrates the strong potential of the micro/nanofibrous matrices to act as carriers of highly volatile repellents for an effective and sustained protection from mosquitoes. Gas chromatography-mass spectrometryGC-MS analyses were conducted using an Agilent Technologies 7820A gas chromatograph equipped with a HP-5MS capillary column (30 m × 0.25 mm, film thickness 0.25 m), an Agilent Technologies 5977B MS detector operating in electron ionization mode at 70 eV and an Agilent Technologies 7693A automatic liquid sampler. Injection was performed at 280 ∘ C in a split ratio Pest Manag Sci 2019; 75: 2142-2147
