Effect of temperature on metabolism of Phlebotomus papatasi (Diptera: Psychodidae).

摘要: Abstract Phlebotomus papatasi (Scopoli) (Diptera: Psychodidae) is the most important vector of Leishmania major, and previous experiments revealed that development in sand fly midgut significantly affected by temperature. Therefore, we maintained blood-fed P. females at 23 or 28°C to understand effect temperature on bloodmeal digestion developmental times this fly. At lower temperature, metabolic processes were slower longer: defecation, oviposition, egg hatch started later took longer complete. Also, mortality was lower. The defecation remains delayed for 12–36 h 23°C compared with group 28°C. Such delay would provide more time establish infection could partially explain increased susceptibility major 23°C. In both experimental groups, laid similar nu...
