Abstract

Long-tailed shrikes, Lanius schach nasutus Scopoli, 1787 and Philippine cockatoos (P.L.S. Muller, 1776), Cacatua haematuropygia were examined for blood and ectoparasites at different periods. Haemoproteus lanii de Mello, 1937 is reported parasitizing the red blood cells (RBC) of the long-tailed shrike in U.P. Los Baños Campus Philippines. Mature gametocytes of this species are of medium size, halteridial in form with entire margins and occupy about 70-75 % of the host's red blood cells. There is little hypertrophy or distortion of the infected host red blood cell and the nucleus of the latter is only slightly displaced by the gametocyte. Cytoplasm of gametocytes appeared granular with large, pronounced, rod-like to broadly ovoid-shaped and yellow brown pigment granules numbering 9-14 which are scattered throughout the cytoplasm but have a tendency to concentrate at each pole or at the middle. Nucleus of gametocytes stained very faintly and is not discernible. Chewing lice (Mallophaga) were collected from three of five Philippine cockatoos examined from Palawan and Mindanao. The collections consisted of two species belonging to two genera as follows: Psittoecus hoogstraali Guimarães, 1974 (Ischnocera) and Franciscoloa thompsoni Price & Beer, 1966. This paper constitutes a new host record for Haemoproteus lanii and the only record for Psittoecus hoogstraali and Franciscoloa thompsoni since their discovery. The three parasite species are briefly described and photographs of them are provided based on the present specimens. The parasites so far reported from the long-tailed shrike and cockatoo in the Philippines are given.
