“…Mosquitoes are characterized by a complex life cycle, in which the immature stages are confined to aquatic habitats, while adults are free ranging within the surrounding terrestrial landscape. The quality of the aquatic habitats utilized by mosquito larvae can vary greatly in space and time (Minakawa et al, 1999;Rejm ankov a et al, 2013;Fader & Juliano, 2014), and this spatio-temporal variation can be manifested at different environmental factors, such as food availability, density of competitors and predators, water salinity, and water temperature, all of which potentially influence female oviposition site selection and larval development (Reiskind & Wilson, 2008;Alto, Muturi & Lampman, 2012;Silberbush, Abramsky & Tsurim, 2015b).…”

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.

“…Our study exemplifies a ‘One Health’ perspective by revealing both positive and negative effects of invasive weed management on mosquito abundance. Researchers and health practitioners are increasingly advocating for a One Health approach emphasizing increased consideration for environmental contexts and using collaboration and interdisciplinary communication for solving health problems (Rejmánková et al 2013, Benelli et al 2017, Johnson et al 2019). There is growing scientific evidence that this strategy has far‐reaching benefits to many levels of health and society, particularly when applied to the integrated control of zoonotic and vector‐borne disease (Okello et al 2011).…”

“…can inhabit a wide range of aquatic spaces but specific habitat preferences by mosquitoes are not well defined (Goddard et al 2002). Different larval mosquito species require different habitat conditions, and conditions can change seasonally (Farajollahi et al 2011, Rejmánková et al 2013). Additionally, many of these habitat spaces change over time and are affected by intense and diverse pest and vegetation control measures.…”

Invasive aquatic weeds are managed with herbicides to reduce their negative impacts on waterways in many areas, including the California Delta Region. Herbicides create a dynamic environment of living and decomposing plant matter that could affect larval mosquitoes and other invertebrates, such as their predators and competitors. Our objective was to compare the number of larval mosquitoes in water or water hyacinth, before and after an herbicide treatment. We created replicated pond mesocosms with water hyacinth, water hyacinth treated with glyphosate and an oil adjuvant, open water, and water with glyphosate plus adjuvant. We sampled for larval mosquitoes and other aquatic invertebrates. Before herbicide addition, there was a trend for more larval mosquitoes in open water tanks than in tanks with water hyacinth. Herbicide application resulted in an immediate decrease of larval mosquitoes. As decay progressed, larval mosquitoes became most abundant in mesocosms with herbicide‐treated hyacinth and very few larval mosquitoes were found in other habitat treatments. Although the numbers of predatory and competitor insects had some variation between treatments, no clear pattern emerged. This information on how invasive weed management with herbicides affects larval mosquitoes will allow control practices for larval mosquitoes and invasive weeds to be better integrated.

“…Este gradiente latitudinal determina características ecológicas propias de la Orinoquia y su transición a la Amazonia con cambios en la vegetación, los vientos y las variables abióticas ambientales específicas que influyen en el desarrollo de la especie (51). Estas características, asociadas con la estacionalidad en el régimen de lluvias, determinan la aparición de criaderos con mayor influencia antrópica unos que otros, muchos con exposición total al sol, en tanto que otros aparecen en el bosque inundado, en donde la relación de nutrientes y sombra permanente es propicia para las formas inmaduras de la especie (26) e influye en su desarrollo embriológico y larval (52).…”

Introducción. Poblaciones naturales de Anopheles darlingi, principal transmisor de malaria en Colombia, han mostrado plasticidad fenotípica en algunos de sus caracteres diagnósticos.Objetivo. Caracterizar variaciones morfométricas en patrones alares y de pata posterior en poblaciones naturales de An. darlingi recolectados en localidades donde la malaria es endémica.Materiales y métodos. Se analizaron mediante morfometría lineal y geométrica, los patrones de manchas de la vena Costa del ala de hembras silvestres recolectadas en los departamentos de Chocó, Guaviare, Meta y Vichada. El segundo tarsómero posterior de las hembras se analizó por morfometría lineal.Resultados. Se encontraron 19 patrones de manchas de la vena Costa, los patrones I con 49 % (n = 118/240) y VI con 28 % (n = 66) correspondieron a los más frecuentes. La proporción DSIII2/TaIII2 constituyó un carácter diagnóstico robusto debido a representó el 89% (n = 213/240) del total de especímenes analizados. Se encontraron diferencias significativas para la forma (F = 1,65, gl = 50, p < 0,001) y el tamaño (F = 3,37, gl = 5, p = 0,005) del ala entre poblaciones de diferentes localidades. El tamaño del centroide más pequeño 2,64 mm se encontró en poblaciones de Chocó.Conclusiones. Se registraron once patrones nuevos para manchas de la vena Costa y se confirma la dominancia de los patrones alares I y VI para poblaciones de An. darlingi de Colombia. Se confirma que la relación DSIII2/TaIII2 constituye un carácter diagnóstico robusto para la taxonomía de la especie. Se encontraron diferencias en el tamaño corporal de las poblaciones evaluadas, lo que reviste importancia para el análisis de aspectos bionómicos de la especie.
