Role of pseudolynchia canariensis in the transmission of haemoproteus turtur from the migrant Streptopelia turtur to new bird hosts in Egypt.

Pseudolynchia canariensis flies offered the naturally infected migrant dove Streptopelia turtur with Haemoproteus turtur succeeded to induce weak infection in the raised Streptopelia turtur only. Intraperitoneal, intramuscular and subcutaneous injection of their salivary glands together with intraperitoneal injection of macerated lung and liver tissues of infected doves revealed the appearance of low and moderate grade parasitaemia in S. senegallus and the raised S. turtur. Flies offered laboratory infected donor doves of low and moderate parasitaemia could transmit the parasite through all the experimental trials during the course of infection with variable degrees of parasitaemia to both doves. All attempts to transmit H. turtur to Columba livia was unsuccessful.
