[Biological cycle of the nematode Rictulariidae: Pterygodermatites (Multipectines) affinis (Jägerskiold, 1904)...

Infestant larva of the Nematode Rictulariidae: Pterygodermatities affinis (Jägerskiold, 1904) are localized in Pimelia: Tachyderma hispida Forskael of Algeria. Through the infestation of a young cat, embryonated eggs are collected after 38 days of development altogether with a female parasite. The experimental cycle of this rictulariid nematode in Locusta migratoria is characterized by the shortness of its development and the similarity in growth during the first and second larval stages. The cellular reaction of the Insect to the larva P. affinis is weaker in the Pimelia than in the Grasshopper, used as experimental host.
