Abstract: Los mosquitos (Diptera: Culicidae) son insectos holometábolos con estadios inmaduros acuáticos que utilizan una amplia variedad de hábitats larvales, desde cuerpos de agua en el suelo hasta Fitotelmata (depósitos de agua en las plantas) y depósitos artificiales. La disponibilidad de sitios de reproducción a menudo determina el límite superior del ámbito de los mosquitos. Nosotros construimos una base de datos de 9 607 registros, 432 localidades, 19 géneros y 254 especies. La coordillera Andina posee el 77% de los registros con mayor altitud incluyendo Aedes euris con un registro a 3 300 m, seguido por tres especies de Anopheles -subgénero Kerteszia- con una altitud máxima de 2 680 m. Wyeomyia bicornis y Culex daumastocampa a 2 550 m fueron los registros de mayor altitud en la cordillera Costera- Central, mientras que el record más alto en Pantepui fue Wyeomyia zinzala a 2 252 m. El 60% de los registros de máxima altitud están representados por especies asociadas con fitotelmata (Bromeliaceae y Sarraceniaceae). Los límites superiores de Culex quinquefasciatus y Anopheles (Kerteszia) podría representar el límite teórico para la transmisión de filariasis o arbovirus, por Culex y malaria por Anopheles (Kerteszia) en Venezuela. Del mismo modo, un vector del dengue, Aedes aegypti, no ha sido registrado por encima de 2 000 m. Highest mosquito records (Diptera: Culicidae) in Venezuela. Mosquitoes (Diptera: Culicidae) are holometabolous insects with aquatic immature stages, which use a broad variety of larval habitats, from ground water bodies to Phytothelmata (water deposits in plants) and artificial deposits. The availability of breeding sites often determines the upper limits of mosquito ranges. We built a database with 9 607 records with 432 localities, 19 genera and 254 species. The Andean mountains have 77% of the highest mosquito records including Aedes euris with record at 3 133 m, followed by three species of Anopheles -subgenera Kerteszia- with the upper limit of 2 680 m. Wyeomyia bicornis and Culex daumastocampa at 2 550 m were the highest records in the Central- Coastal cordillera, while the highest record in Pantepui was Wyeomyia zinzala at 2 252 m. The species associated with phytothelmata (Bromeliaceae and Sarraceniaceae) represent 60% of the records. The upper limits of Culex quinquefasciatus and Anopheles (Kerteszia) species could represent the theoretical limit for transmission of filariasis or arboviruses, by Culex, and malaria by Anopheles (Kerteszia) in Venezuela. Similarly, a vector of Dengue, Aedes aegypti, has not been not recorded above

Abstract: Objective: The ability of the native larvivorous fish Aplocheilus panchax (Hamilton, 1822) (Cyprinodontiformes:Aplocheilidae) as predator of mosquito larvae was assessed under laboratory conditions using multiple prey andhabitat conditions.Methods: The consumption of larvae of the mosquito Culex quinquefasciatus Say 1823 (Diptera: Culicidae) byA. panchax was evaluated in the presence of tubificid worms and chironomid larvae under complex and simplehabitat conditions. The number of mosquito larvae consumed in comparison to other prey types was noted andan index of prey selectivity was used to evaluate the preference for mosquito larvae.Results: Aphlocheilus panchax consumed 53 to 65 mosquito larvae in a three hour feeding bout contrast to 29–38 tubificid worms and 43–62 chironomid larvae depending on the habitat conditions. The prey consumptiondiffered significantly between the habitats and the prey type. The index of prey selectivity was positive for Cx.quinquefasciatus larvae over other alternative prey in all the habitat conditions.Conclusion: It is apparent from the study that the larvivorous fish A. panchax can be employed for biologicalregulation of mosquitoes in rice-fields and similar wetlands where the multiple prey choices are available undercomplex habitat conditions. However, field studies including other prey species will be required to substantiatethis finding

Abstract: Se realizaron regresiones logísticas múltiples para identificar las variables ambientales cuantitativas y cualitativas que permitiesen predecir la ocurrencia de las diferentes especies de mosquitos culícidos (Diptera: Culicidae) recolectadas durante cuatro a os de estudio (2005-2008) en el este de la Península Ibérica. Los resultados muestran que algunas variables posibilitan el alcance de óptimos porcentajes de incidencia para las especies Ochlerotatus caspius, Culex pipiens, Culex territans y Culiseta longiareolata. El estudio de posibles elementos predictivos de la ocurrencia de culícidos se postula como una herramienta útil y conveniente para el establecimiento de exitosos programas de control poblacional de mosquitos. Multiple logistic regressions were conducted to identify the quantitative and qualitative environmental variables that best predict the occurrence of the different species of culicid mosquitoes (Diptera: Culicidae) collected over four years of study (2005-2008) in the eastern Iberian Peninsula. The results show that some variables make it possible to achieve optimal percent incidence for the species Ochlerotatus caspius, Culex pipiens, Culex territans and Culiseta longiareolata. The study of possible predictive elements for the occurrence of culicids is postulated as a useful and convenient tool for the establishment of successful mosquito population control programs.

Abstract: Several larval samplings of mosquitoes (Diptera, Culicidae) in different mountainous regions of the peninsular Spain were carried out. A total of 2796 specimens belonging to 18 species were collected, nevertheless the 72.5 % of these finds includes only three of them (Cx. hortensis hortensis, Cx. pipiens and Cs. longiareolata). The adaptation capacity to a varied typology of water bodies together with the marked multivoltinism that characterizes their biotic cycles are postulated as two of the principal reasons that explain their abundances. The altitudinal distribution as well as some information about the bioecology of all the species captured are also exposed. Se realizaron diversos muestreos larvarios de mosquitos (Diptera, Culicidae) en varias regiones monta osas de la Espa a peninsular. Pese a que se recolectaron un total de 2796 ejemplares pertenecientes a 18 especies, el 72.5 % de estos hallazgos engloba únicamente a tres de ellas (Cx. hortensis hortensis, Cx. pipiens y Cs. longiareolata). La capacidad de adaptación a un variado elenco de cuerpos de agua de diferente tipología, unida al marcado multivoltinismo que caracteriza sus ciclos bióticos, se postulan como dos de las principales razones que explican sus abundancias. La distribución altitudinal así como diversa información acerca de la bioecología de todas las especies capturadas también se exponen en el presente trabajo.

Abstract: Background & objectives: Indigenous larvivorous fishes bear potential for regulating vector mosquitoes throughtrophic interactions. The mosquito prey preference of five indigenous larvivorous fishes in the presence of alternativefood items was assessed to highlight their use in mosquito vector management.Methods: Laboratory experiments were carried out using the larvivorous fishes Ambassis (=Chanda) nama,Parambassis (=Chanda) ranga, Colisa fasciatus, Esomus danricus and Aplocheilus panchax, as predators and IVinstar Culex quinquefasciatus larvae as target prey. Mosquito prey preference of these fishes in the presence ofchironomid larvae, tubificid worms and artificial fish foods, in varied proportions, were assessed using preferenceindex.Results: The fishes consumed considerable amount of mosquito larvae both in absence and presence of alternativefood items. However, the positive selectivity for mosquito larvae at all densities were significantly (p <0.05)affected by the alternative foods. The chironomid larvae and tubificid worms were consumed proportionatelyhigher than expected (p <0.05), while the artificial fish food was consumed at lower than expected proportions(p <0.05). The niche overlap was significantly similar among the fish species suggesting likeliness in predationpattern and prey preference.Interpretation & conclusion: The results reflect that the alternative food items influence the mosquito prey selectivityand thus the efficacy of indigenous larvivorous fishes. While use of these fishes in the wetlands and allied mosquitolarval habitats in different parts of the country is suggested, impact of the alternative prey may affect the successfulregulation of mosquitoes. Assessment of appropriate predator-prey ratio under natural habitat conditions isrecommended to enhance successful mosquito control by these fishes.
