[Observations on the development of Phlebotomus papatasi Scop. under laboratory conditions]

The development of Phlebotomus papatasi Scop., 1786 was observed at a laboratory of the Martsinovskiĭ Institute of Medical Parasitology and Tropical Medicine in 1988-1994. There was a flight of 9,809 imagoes. Among the mosquitoes developed from spring (May-June) clutches, most imagoes (as high as 98.9% of the total number of the flying imagoes) flew out in summer. As high as 6.7% flew out in autumn and up to 16.8 & of the total number did after diapause, i.e. the following spring. The paper shows it possible to interrupt the diapause on exposure larvae to elevated temperatures and light. However, mosquitoes of different strains are responsive to light in varying degrees. P. papatasi from Turkmenistan developed in the dark best al all, which is natural for them since in nature their breeding mainly occurs in the Arenaria burrows. The mosquitoes of mixed strains (females from Arabia, males from Turkmenistan) most frequently flew out in day and night light.
