“…Much recent literature has focused on effects of odonates and hemipterans as predators and oviposition deterrents of mosquitoes (Arav and Blaustein 2006;Blaustein 1998;Blaustein et al 2004;Bond et al 2006;Quiroz-Martinez et al 2005;Shaalan et al 2007;Spencer et al 2002;Stav et al 1999Stav et al , 2000Yanoviak 1999Yanoviak , 2001. We found a negative, but nonsigniÞcant, trend between the density of mosquitoes and densities of Odonata and Hemiptera (linear regressions: r 2 ϭ 0.022, F 1, 178 ϭ 4.001, P ϭ 0.047, and r2 ϭ 0.041, F 1, 178 ϭ 7.581, P ϭ 0.007, respectively, critical ␣ ϭ 0.002).…”

Studies that consider both biotic and abiotic determinants of organisms are rare, but critical to delineate underlying determinants of community richness (number of taxa) and abundance (number of larvae per water body). In this study, we consider the importance of disturbance (salinity) and predator and competitor variables on mosquitoes (Diptera: Culicidae) in small ephemeral water bodies across the Wheatbelt of Western Australia. Similar to mosquitoes, and contrary to general perceptions, nonculicid aquatic fauna (aquatic fauna) had a common occurrence (number or percentage of water bodies occupied) and were abundant (average density) in ephemeral water bodies, albeit with a simplified trophic structure. The occurrence and density (number per unit area) of aquatic fauna between water bodies were highly variable, but general relationships of aquatic fauna with rainfall, water body surface area, salinity, and mosquitoes were apparent. In contrast to mosquitoes, the density of aquatic fauna declined with recent rainfall, implying mosquitoes may colonize newly created water bodies more quickly than aquatic fauna. Assemblages (richness and density of taxa) of aquatic fauna changed along a salinity gradient, as did mosquitoes, and this was pronounced for predator groups. Densities of mosquitoes were not limited by any single taxonomic group, by a negative relationship. However, the density and richness of mosquitoes generally declined in association with increased richness of predators and density of all other taxa (taxa not specifically classified as predators or competitors of mosquitoes). These relationships may account for higher densities of mosquitoes in smaller water bodies, where richness of predators is reduced and the density of other taxa does not differ from larger water bodies. Our results also suggest salinity in the Western Australia Wheatbelt may facilitate greater abundance of halotolerant mosquitoes, Aedes alboannulatus Macquart and Aedes camptorhynchus Thomson (a vector of Ross River virus [Togoviridae: Alphavirus]), by releasing them from biotic regulation.

“…En tanto B. fasciata al ser un depredador que comparte el mismo hábitat de las larvas de Ae. aegypti, muestra menor efecto sobre la densidad larval relacionado probablemente con el equilibrio entomófago-presa, condicionado al consumo solo de lo necesario para satisfacer el requerimiento alimenticio evitando la extinción del recurso en control, que implica en términos biológicos eficiencia en la respuesta antidepredación de la presa y el posible ajuste coevolutivo entre ambos organismos establecido por selección natural a lo largo de cientos de miles de años, que evita la desaparición de una de las dos poblaciones (Fernández-Arhex y Corley 2004;Quiroz-Martínez et al 2005).…”

La depredación es un factor biótico que influye en la estructura y funcionamiento de los ecosistemas, su efecto se puede cuantificar a través de la respuesta funcional (RF) y numérica en un contexto de éxito-invasión. Utilizamos la RF para entender las relaciones coevolutivas y medir la respuesta biológica de los depredadores Notonecta peruviana y Buenoa fasciata en el control de larvas de cuarto estadio de Aedes aegypti (F1) a diferentes densidades (5, 10, 20, 35, 55 y 80 larvas/litro). Los depredadores en ayuno (48 horas) se introdujeron a los envases de ensayo (un individuo por especie) y se evaluó a las 24 horas la RF, número de presas consumidas (Ne), coeficiente de ataque (a) y tiempo de manipuleo (Th). N. peruviana y B. fasciata desarrollaron una RF tipo II en el consumo de larvas de Ae. aegypti (p ≤ 0,01) y ocuparon cercanos tiempos de manipuleo (Th) (t = –1,93; gl = 12; p = 0,078). N. peruvianadepredó (Ne) el doble de larvas de Ae. aegypti (p ≤ 0,05) y mostró un mayor coeficiente de ataque (a) en relación con B. fasciata (t = 14,92; gl = 12; p = 0,000). Los depredadores N. peruviana y B. fasciata desestabilizaron y consumieron en forma rápida las presas. N. peruviana devoró el doble de larvas atribuible al efecto depredador-presa de origen reciente en comparación al posible ajuste coevolutivo entre B. fasciata y Ae. aegypti. Sería importante considerar a las especies de depredadores en los programas de control larval de mosquitos aedinos.

“…riparius ), suggesting a possible feeding preference for mosquitoes, which is in line with previous observations [ 18 ]. Other studies on feeding preference of dragonfly larvae (Pantala hymenaea) showed a slight preference for Chironomidae over Culicidae [ 39 ], indicating a possible difference between Odonata and Hemiptera species. These results thus indicate apparent competition between Chironomidae and Culicidae, which is important for potential use of predators in mosquito and mosquito-borne disease control [ 17 , 37 ], because prey specificity is an important component of biological control.…”

Eutrophication and predator presence overrule the effects of temperature on mosquito survival and development

Adequate predictions of mosquito-borne disease risk require an understanding of the relevant drivers governing mosquito populations. Since previous studies have focused mainly on the role of temperature, here we assessed the effects of other important ecological variables (predation, nutrient availability, presence of conspecifics) in conjunction with the role of temperature on mosquito life history parameters. We carried out two mesocosm experiments with the common brown house mosquito, Culex pipiens, a confirmed vector for West Nile Virus, Usutu and Sindbis, and a controphic species; the harlequin fly, Chironomus riparius. The first experiment quantified interactions between predation by Notonecta glauca L. (Hemiptera: Notonectidae) and temperature on adult emergence. The second experiment quantified interactions between nutrient additions and temperature on larval mortality and adult emergence. Results indicate that 1) irrespective of temperature, predator presence decreased mosquito larval survival and adult emergence by 20–50%, 2) nutrient additions led to a 3-4-fold increase in mosquito adult emergence and a 2-day decrease in development time across all temperature treatments, 3) neither predation, nutrient additions nor temperature had strong effects on the emergence and development rate of controphic Ch. riparius. Our study suggests that, in addition to of effects of temperature, ecological bottom-up (eutrophication) and top-down (predation) drivers can have strong effects on mosquito life history parameters. Current approaches to predicting mosquito-borne disease risk rely on large-scale proxies of mosquito population dynamics, such as temperature, vegetation characteristics and precipitation. Local scale management actions, however, will require understanding of the relevant top-down and bottom-up drivers of mosquito populations.
