Resumen
Se han reportado larvas del mosquito Uranotaenia novobscura ryukyuana Tanaka et al. en huecos de árboles, tocones de bambú y recipientes de agua artificiales. Hasta ahora, ningún estudio ha abordado el papel que la dependencia de la densidad y las fluctuaciones climáticas podrían haber jugado en la abundancia de este mosquito no vector. Se realizó un estudio de un año sobre la dinámica poblacional de este mosquito utilizando trampas de oviposición en Okinawa, Japón. Se utilizaron análisis de series temporales y el modelo de población de Ricker para analizar la asociación entre la densidad de mosquitos y el crecimiento de la población y las fluctuaciones en la humedad relativa, la temperatura y las precipitaciones. Nuestros resultados sugieren que Ur. novobscura ryukyuana tiene una dinámica denso-dependiente estable, que es autónoma de las fluctuaciones climáticas. Nuestros resultados fueron opuestos a los patrones observados en otras especies de mosquitos subtropicales, cuya dinámica poblacional podría estar parcialmente determinada por fluctuaciones climáticas, lo que resalta la diversidad de respuestas que los mosquitos pueden tener a los cambios ambientales.
Larvae of the mosquito Uranotaenia novobscura ryukyuana Tanaka et al., have been reported in tree-holes, bamboo stumps, and artiÞcial water containers. So far, no study has addressed the role that density dependence and weather ßuctuations could have played in the abundance of this nonvector mosquito. A year-long study was conducted on the population dynamics of this mosquito using oviposition traps in Okinawa, Japan. Time series analysis and the Ricker population model were used to analyze the association between mosquito density and population growth and ßuctuations in relative humidity, temperature, and rainfall. Our results suggest that Ur. novobscura ryukyuana has stable denso-dependent dynamics, which are autonomous from weather ßuctuations. Our results were opposite to patterns observedin other subtropical mosquito species, whose population dynamics might be partially driven by weather ßuctuations, thus highlighting the diversity of responses that mosquitoes can have to changing environments.
