The Asian tiger mosquito, Aedes albopictus, is a highly invasive vector species. It is a proven vector of dengue and chikungunya viruses, with the potential to host a further 24 arboviruses. It has recently expanded its geographical range, threatening many countries in the Middle East, Mediterranean, Europe and North America. Here, we investigate the theoretical limitations of its range expansion by developing an environmentally-driven mathematical model of its population dynamics. We focus on the temperate strain of Ae. albopictus and compile a comprehensive literature-based database of physiological parameters. As a novel approach, we link its population dynamics to globally-available environmental datasets by performing inference on all parameters. We adopt a Bayesian approach using experimental data as prior knowledge and the surveillance dataset of Emilia-Romagna, Italy, as evidence. The model accounts for temperature, precipitation, human population density and photoperiod as the main environmental drivers, and, in addition, incorporates the mechanism of diapause and a simple breeding site model. The model demonstrates high predictive skill over the reference region and beyond, confirming most of the current reports of vector presence in Europe. One of the main hypotheses derived from the model is the survival of Ae. albopictus populations through harsh winter conditions. The model, constrained by the environmental datasets, requires that either diapausing eggs or adult vectors have increased cold resistance. The model also suggests that temperature and photoperiod control diapause initiation and termination differentially. We demonstrate that it is possible to account for unobserved properties and constraints, such as differences between laboratory and field conditions, to derive reliable inferences on the environmental dependence of Ae. albopictus populations.

“…Other studies though suggest that this link is weaker under natural conditions, such as when considering time limitations for oviposition (Gotthard, Berger & Walters, 2007). In addition, females' longevity is often longer than that of the males (Calado & Navarro-Silva, 2002;Andreadis, Dimotsiou & Savopoulou-Soultani, 2014). Thus, accelerated growth rate might result in reduced adult female survival, directly translating into a reproduction disadvantage (i.e.…”

Interactive and sex‐specific life‐history responses ofCulex pipiensmosquito larvae to multiple environmental factors

et al. 2018

Spatio‐temporal variation in aquatic habitat characteristics can have important implications for the population and community dynamics of organisms utilizing these habitats. We studied the life‐history responses of Culex pipiens larvae (Diptera: Culicidae) to multiple environmental factors associated with habitat drying by increasing larval density (directly affecting resource availability), temperature fluctuations (influencing physiological processes), and solute concentration due to evaporation (inducing an environmental stress), using a full‐factorial design. We found that high density led to lower larval survival and to shorter development time. Larvae delayed their metamorphosis in response to fluctuating temperature. We detected inter‐sexual differences in the effects of these two factors on adult body sizes, with high larval density leading to the emergence of smaller females, and fluctuating temperature translating to larger adult males. The two sexes also differed concerning the two‐way interactive effects of different environmental factors on development time and on adult size. Our findings indicate that C. pipiens larvae respond to multiple environmental factors via phenotypic plasticity, rather than through bet‐hedging. Future studies should account for additional inter‐stage effects, rather than body size, such as adult fecundity, longevity, and dispersal.

“…Ribeiro et al (2001) constataram que a 30°C, sob condições de laboratório, Ophyra aenescens Wiedemann (Diptera: Culicidae), apresenta 19,9 gerações por ano, com viabilidade total de 75,9%. Calado & Navarro-Silva (2002a) relataram que a atividade hematofágica e a oviposição de Aedes albopictus Skuse, sofrem infl uência da temperatura, e que as baixas temperaturas de 15°C e 20°C atuam como fator limitante ao crescimento populacional do inseto. Para esses autores, a eliminação dos criadouros artifi ciais nos meses mais frios, pode ser uma forma de diminuição da população de fêmeas aptas a realizar o repasto sangüíneo.…”

-The present work aimed at estimating the thermal requirements for the development and the number of generations per year of Aedes aegypti (L.) under natural conditions. The life cycle of A. aegypti populations was studied at constant temperatures of 18, 22, 26, 30 and 34ºC, and 12h photophase. The development period, egg viability and larval and pupal survival were evaluated daily as well as adult longevity and fecundity. The low threshold temperature of development (Tb) and the thermal constant (K) were determined. The number of generations per year in laboratory and fi eld were also estimated. The favorable temperature to A. aegypti development is between 21ºC and 29ºC, and to longevity and fecundity is between 22ºC and 30ºC. The egg to adult basal temperature, thermal constant and the number of generations in fi eld were, in order, 9.5, 8.5, 3.4, 7.1, 13.5ºC; 244.5, 273.9, 298.5, 280.9 and 161.8 degree-days; and 21.9, 23.8, 24.2, 21.1 and 22.1 generations in populations from Boqueirão, Brejo dos Santos, Campina Grande, Itaporanga and Remígio.KEY WORDS: Insecta, vector, biological cycle, temperature RESUMO -O trabalho teve por objetivo determinar as exigências térmicas para o desenvolvimento e estimar o número de gerações anuais de Aedes aegypti (L.) em campo. O ciclo biológico das populações de A. aegypti foi estudado nas temperaturas constantes de 18, 22, 26, 30 e 34ºC, e fotofase de 12h. Foram avaliados, diariamente, o período de desenvolvimento e a viabilidade da fase de ovo, sobrevivência de larva e pupa, longevidade e a fecundidade dos adultos, determinando-se, ainda, os limites térmicos inferiores de desenvolvimento (Tb) e as constantes térmicas (K). Em função dessas variáveis foram estimados os números de gerações anuais do inseto em laboratório e campo. A temperatura favorável ao desenvolvimento de A. aegypti encontra-se entre 21ºC e 29ºC, e para a longevidade e fecundidade os adultos entre 22ºC e 30ºC. As Tb s , K s de ovo a adulto, e o número de gerações anuais em campo foram de 9,5, 8,5, 3,4, 7,1, 13,5ºC; 244,5, 273,9, 298,5, 280,9 e 161,8 graus-dias; e 21,9, 23,8, 24,2, 21,1 e 22,1 gerações para as populações de A. aegypti das regiões de Boqueirão, Brejo dos Santos, Campina Grande, Itaporanga e Remígio, respectivamente. PALAVRAS-CHAVE: Insecta, vetor, ciclo biológico, temperaturaAedes (Stegomyia) aegypti (L.) é um importante vetor em saúde pública devido a seu papel como transmissor de dengue e de febre amarela. É um mosquito com ampla distribuição geográfi ca, predominando nas áreas tropicais e subtropicais situadas entre os paralelos de latitudes 45° Norte e 40° Sul (Forattini 2002) e nas zonas isotermais intermediadas a 20ºC (Gadelha 1985). Devido ao seu hábito antropofílico, A. aegypti apresenta grande capacidade de adaptação a criadouros artifi ciais o que possibilita o aumento de sua população e, por conseguinte, o aparecimento de epidemias de dengue (Lozovei 2001).A temperatura é um dos principais fatores ecológicos que infl ui tanto direta como indiretamente sobre os insetos,...
