Abstract

Cutaneous leishmaniasis is one of the most important vector-borne endemic diseases in Turkey. The main objective of this study was to evaluate the influence of temperature on the developmental rates of one important vector of leishmaniasis, Phlebotomus papatasi (Scopoli, 1786) (Diptera: Psychodidae). Eggs from laboratory-reared colonies of Phlebotomus papatasi were exposed to six constant temperature regimes from 15 to 32 degrees C with a daylength of 14 h and relative humidity of 65-75%. No adult emergence was observed at 15 degrees C. Complete egg to adult development ranged from 27.89 +/- 1.88 days at 32 degrees C to 246.43 +/- 13.83 days at 18 degrees C. The developmental zero values were estimated to vary from 11.6 degrees C to 20.25 degrees C depending on life stages, and egg to adult development required 440.55 DD above 20.25 degrees C.
