Exposure of female lice to infective juveniles (IJs) of Steinernema carpocapsae ''Pye'' strain and S. glaseri in a Petri-dish assay resulted in high mortality levels (> 85 %) within 24 h. Among female lice exposed to as of the ''HP88'' strain of Heterorhabditis bacteriophora 45 % mortality was recorded after 42 h exposure. Lice exposure to the ''Mexican'' strain of S. carpocapsae for 42 h resulted in 65 % mortality. The mortality of the louse females was directly related to increased dosage of S. glaseri IJs. Complete lice mortality was achieved with this nematode at 400 IJs/dish. Exposure of the lice to 800 IJs of H. bacteriophora HP88/dish resulted in 27.5 % mortality. The highest number of nematodes was recovered from dead lice infected with S. glaseri (7.7 nematodes/louse). Abnormal development was observed among females of S. glaseri. which were shrunken, whereas males developed normally. The lowest number (0.2 nematodes/louse) was recorded in the lice infected with the ''HP88'' strain of H. bacteriophora.10aheterhabditidae10aNematoda10apdf10aPediculus humanus humanus10asteinernematidae1 aWeiss, Margalit1 aGlazer, Itamar1 aMumcuoglu, Kosta, Y.1 aElking, Yonatan1 aGalun, Rachel  uhttp://www.phthiraptera.info/Publications/38450.pdf
