Development of Simulium (Psilozia) vittatum Zett. (Diptera: Simuliidae) from Larvae to Adults at Thermal Increments from 17.0 to 27.0 C

Development of Simulium (Psilozia) vittatum Zett. (Diptera: Simuliidae) from Larvae to Adults at Thermal Increments from 17.0 to 27.0 C

Exposure of 5-day-old larval S. vittatum to 2.5 C thermal increments ranging from 17.0-27.0 C proportionally increases the rate of development through the pupal to adult stage. A 10 C rise in temperature reduces the subsequent mean development span by about half, from 8 days at 17 C to 4 days at 27...

Zusammenfassung:Exposure of 5-day-old larval S. vittatum to 2.5 C thermal increments ranging from 17.0-27.0 C proportionally increases the rate of development through the pupal to adult stage. A 10 C rise in temperature reduces the subsequent mean development span by about half, from 8 days at 17 C to 4 days at 27 C. Temperatures of 27 C appear to be within the upper thermal tolerance of the species.
