本文报道了在长须白蛉（Lutzomyialongipalpis）哥伦比亚品系中发现的无隔虫囊蝇Ascogregarinachagasi（Adler和Mayrink），用其喂养七种实验室饲养的白蛉（Phlebotomuspapatasi（Scopoli），P. argentipesAnnandale和Brunetti，P. perniciosusNewstead，L. serrana（Damasceno and Arouck），L. abonnenci（Floch and Chassignet）、拟山核桃L.科隆比亚纳（Ristorcelli和货车Ty）和不含gregarinefree的巴西L.长须的从四种白蛉成虫中分离到了该虫的滋养体：帕帕塔沙白蛉、L.塞拉纳湖科隆比亚纳和巴西株L. longipalpis;寄生虫只能在巴西菌株L.长须的感染率和虫口密度。chagasi在哥伦比亚株L.巴西品种的长须鱼感染A. chagasi显著降低了巴西株L. longipalpis，但对繁殖力影响不大。
The aseptate gregarine,Ascogregarina chagasi(Adler and Mayrink), found in a Colombian strain ofLutzomyia longipalpis(Lutz and Neiva), was fed to the larvae of seven species of laboratory-bred sand flies:Phlebotomus papatasi(Scopoli),P. argentipesAnnandale and Brunetti,P. perniciosusNewstead,L. serrana(Damasceno and Arouck),L. abonnenci(Floch and Chassignet),L. columbiana(Ristorcelli and Van Ty), and a gregarinefree Brazilian strain ofL. longipalpis. Trophozoites of the gregarine were recovered from adult sand flies of four species:P. papatasi, L. serrana, L. columbiana, and the Brazilian strain ofL. longipalpis; the parasites were able to complete their life cycle only in the Brazilian strain ofL. longipalpis. The infection rate and parasite density ofA. chagasiwere higher in the Colombian strain ofL. longipalpisthan in the Brazilian strain. Infection withA. chagasisignificantly reduced adult longevity of the Brazilian strain ofL. longipalpis, but it had little effect on fecundity.
