On the development, morphology, and experimental transmission of diplotriaena bargusinica (filarioidea : diplotriaenidae)

Abstract: Eggs of Diplotriaena bargusinica from worms found in a Hylocichla fuscescens from Algonquin Park, Ontario, hatched and developed in the fat body of grasshoppers (Melanoplus bilituratus, M. fasciatus, Camnula pellucida). At approximately 30–33 °C the first molt took place on the 9–11th day, the second on the 14–16th day. Most second- and third-stage larvae were enveloped in capsules, more than one larva often being present in a single capsule. The larval stages from grasshoppers are described. Grasshoppers with infective larvae were fed to two H. fuscescens, one H. ustulata. one Turdus migratorius, and one Quiscalus quiscula. Subadult worms were found in the two H. fuscescens and the H. ustulata 55–301 days later but none was found in the other birds examined 78–97 days later. Late fourth-stage larvae from the heart and aorta of a nestling H. ustulata captured in the field are described. It is believed tridents first make their appearance during development in the definitive host from the infective stage t...
