Dipetalonema dessetae se développe en 27 jours à 25° dans le tissu adipeux d’Anopheles Stephensi ; la larve se raccourcit au premier stade ; la queue du 3e stade infectant porte trois languettes terminales de même longueur ; les papilles céphaliques ont une disposition évoluée en rectangle. Parmi les cycles de Dipetalonema de Rongueurs connus, la morphogenèse de D. dessetae Bain, 1973, parasite d’Echimyidae, ne ressemble qu’à celle de D. arbuta Highby, 1943, parasite d’Erethizontidae ; les données larvaires confirment ainsi que les Dipetalonema de Rongeurs anciens sud-américains forment un groupe bien homogène, distinct des autres Dipetalonema de Rongeurs, ces dernières étant très disparates.
Abstract
At 25 °C the larvae of Dipetalonema dessetae develop in 27 days in the adipose tissue of Anopheles stephensi. Reduction of size occurs during the first stage. At the third infective stage the tail bears three distal lappets of equal length, and the cephalic papillae are arranged in a rectangular highly-evoluted pattern.
Among all known cycles of Dipetalonema of Rodents, the morphogenesis of Dipetalonema dessetae parasite of Echimyidae is found to be similar only to this of D. arbuta a parasite of Erethizontidae. Thus the data on larval morphogenesis confirm that the Dipetalonema of most primitive south-american Rodents are included in a fairly homogeneous group. They are distinct from the other Dipetalonema of Rodents which are considered as a very disparate group.
