Resumen
We investigated how ambient temperature under fluctuating conditions affects the larval–pupal immature traits of Aedes aegypti and Culex quinquefasciatus mosquitoes from Córdoba city, Argentina, and established each species development threshold and physiological time. Based on life tables, three cohorts of each mosquito species were reared in the laboratory under small fluctuating temperatures conditions of 15.2 ± 1.7 °C, 17.9 ± 1.6 °C, 21.6 ± 0.7 °C and [ver mas...]

dc.description.abstractWe investigated how ambient temperature under fluctuating conditions affects the larval–pupal immature traits of Aedes aegypti and Culex quinquefasciatus mosquitoes from Córdoba city, Argentina, and established each species development threshold and physiological time. Based on life tables, three cohorts of each mosquito species were reared in the laboratory under small fluctuating temperatures conditions of 15.2 ± 1.7 °C, 17.9 ± 1.6 °C, 21.6 ± 0.7 °C and 25.3 ± 0.4 °C for Ae. aegypti, and 16.6 ± 1.7 °C, 18.7 ± 1.7 °C and 25.2 ± 0.3 °C for Cx. quinquefasciatus. Immature development time and survival values, and also thermal development threshold and physiological time were estimated. Development times of all larval and pupal stages of Ae. aegypti and Cx. quinquefasciatus were significantly affected by the rearing temperatures, decreasing when temperature increased. Mean Ae. aegypti total (larva + pupa) development time ranged from 21.9 to 8.6 days, at 15.2 and 25.3 °C, whereas, for Cx. quinquefasciatus varied between 23.5 to 9.2 days at 16.6 and 25.2 °C, respectively. Larval and pupal survival of both species was affected by different rearing temperatures, increasing in general as temperature increased. For Ae. aegypti the total immature survival ranged from 26% at 15.2 °C to 92% at 21.6 °C; however, temperature did not have significant effect on this variable. The total immature survival of Cx. quinquefasciatus was significantly and positively affected by temperatures, ranging from 32 to 88%, at 16.6 and 25.2 °C. The temperature development threshold and the physiological time estimated for Ae. aegypti and Cx. quinquefasciatus were 11.11 °C and 93.74 degree-days, and 10.96 °C and 136.87 degree-days, respectively. The results of the present study showed that temperature significantly affects the larval–pupal immature traits of these mosquito species of sanitary importance, from the central region of Argentina. All the parameters recorded are useful for the development of mosquito management models.eng
