Silverman J, Platzer E G, Rust M K (1982). Infection of the Cat Flea, Ctenocephalides felis (Bouché) by Neoplectana carpocapsae Weiser. Journal of Nematology, Jul;14(3):394-7. Retrieved from https://pubmed.ncbi.nlm.nih.gov/19295728/?


Infection of cat flea, Ctenocephalides felis, larvae by the entomophilic nematode Neoaplectana carpocapsae was accomplished in the laboratory. The Breton strain of N. carpocapsae provided higher larval mortality at lower dosages than did the DD-136 strain. Adult nematodes were evident in the insect hemocoel after 48 h; however, no infective third-stage larvae were produced. Larval flea infection increased with an increase in the moisture content of sand from 2% to 7% and of sandy clay from 7% to 12%. Larval flea infection was also obtained on turf containing dauer larvae. Nematode penetration of cocoons with invasion of prepupal and pupal fleas was apparent.
