Présence de Spirura guianensis (Ortlepp, 1924) chez des Marsupiaux néotropicaux
Cycle évolutif
Laboratoire de Zoologie (Vers) associé au C.N.R.S., Muséum national d’Histoire naturelle, 57, rue Cuvier, F 75005 Paris, France.
Le Nématode Spiruride Spirura guianensis (Ortlepp, 1924) récolté jusqu’alors chez des Primates néotropicaux est identifié chez différentes espèces de Marsupiaux de Guyane : Caluromys philander (L.), Marmosa cinerea amarare Thomas et Philander (Metachirops) oppossum (L.).
Le développement larvaire des trois premiers stades du Nématode est obtenu expérimentalement chez l’Insecte Locusta migratoria.
L’ontogenèse céphalique révèle que les structures péribuccales des larves infestantes sont différentes de celles du 4e stade et de l’adulte, et indique une évolution par rapport aux structures céphaliques plus simples des espèces Spirura talpae, S. rytipleurites seurati et S. portesiana.
Abstract
Occurrence of Spirura guianensis (Ortlepp, 1924) in neotropical marsupials and study of its life-cycle.
The Nematode Spiruridae Spirura guianensis (Ortlepp, 1924) which was known to occur in neotropical primates has been identified as a parasite of several species of marsupials from Guiana : Caluromys philander (L.), Marmosa cinerea amarare Thomas and Philander (Metachirops) opposum (L.).
The larval development of the first three stages was experimentally obtained in the insect Locusta migratoria.
The study of the head ontogenesis has shown that the peribuccal structures of the infestant larvae are different from those observed in the fourth stage and the adult. This indicates a higher evolutionary grade in respect to the simpler cephalic features present in the species Spirura talpae, S. rytipleurites seurati and S. portesiana.
