Considérations sur la deuxième mue des larves d’Ascaridia galli
Observations on the second moult of the larvae of Ascaridia galli
Département de Parasitologie, Institut de Sciences biomédicales, Université de São Paulo, Brésil.
Chez des larves d’Ascaridia galli obtenues par éclosion artificielle, la présence de deux cuticules distinctes décollées du corps des larves est plus fréquente après 11 et 12 jours qu’après 10 et 14 jours d’incubation à la température de 25 °C. Ces cuticules indiquent que les larves de ce nématode effectuent deux mues avant l’éclosion et, par conséquent, que ses larves infestantes appartiennent au troisième stade du développement.
Abstract
In Ascaridia galli larvae artificially hatched after 11 and 12 days of incubation at 25 °C, in larger frequency than in larvae hatched either after 10 and after 14 days of incubation, two different cuticles detached from their bodies were observed. These two detached cuticles indicate that such larvae had undergone two moults before hatching and, consequently, that the infective stage of A. galli is the third larval stage.
