Cycle biologique expérimental du Nématode Rictulariidae : Pterygodermatites taterilli (Baylis, 1928) dont l’adulte parasite fréquemment le Rongeur africain Taterillus gracilis (Thomas).
Les trois premiers stades larvaires évoluent dans la paroi de l’iléon des Orthoptères : Locusta migratoria L. et Schistocerca gregaria Forsk.
Deux larves du quatrième stade et un adulte mâle sont obtenus respectivement après quatre et sept jours de développement chez le Rongeur.
La récapitulation ontogénique des structures céphaliques des 3e et 4e stades larvaires paraît justifier les divisions subgénériques fondées précédemment dans le genre Pterygodermatites sur la différenciation croissante des caractères céphaliques génitaux et cuticulaires des adultes.
Abstract
Experimental biological cycle of the Rictulariidae Nematode Pterygodermatites taterilli (Baylis, 1928) the adult which is known as a frequent parasite of the African Rodent Taterillus gracilis (Thomas).
The first three larval stages occur in the ileon wall of the Orthopterans : Locusta migratoria L. and Shistocerca gregaria Forsk.
In this Rodent, two fourth stage larvae and one male adult were obtained after four and seven days of development, respectively. The ontogenic recapitulation of cephalic structures obseived in the third and fourth larval stages seems to confirm the subgeneric separations which were formerly based on the increasing differentiation of cephalic, genital and cuticular characters of the adults.
