Biology of Two Species of the Protocalliphora (Diptera : Calliphoridae) in Tokachi, Hokkaido, Japan : Relationship between the Occurrence and Three Species of Host Birds
Parus major, Passer rutilans and Sturnus philippensis were new host records for Protocalliphora maruyamensis KANO et SHINONAGA, and Sturnus philippensis was also a new host record for Protocalliphora azurea FALLEN. Nestlings of Parus major were very often parasitized by the larvae of P. maruyamensis and sometimes by the larvae of P. azurea. The number of the larvae per nest was significantly more in P. maruyamensis than in P. azurea. The nestlings of Sturnus philippensis were also often infested with a large number of P. maruyamensis larvae. Nestlings of Passer rutilans were sometimes parasitized by a small number of P. maruyamensis and P. azurea larvae. In 1986,the number of P. maruyamensis larvae in the nest of P. major was large from June 15 to July 10 and thereafter decreased gradually till August 10,while in 1987,the number was very large from June 5 to 15,then decreased to the level in June of 1986 and remained constant until July 5. Thereafter it decreased rapidly and no parasite was found in the nests collected after July 15.
