Family Steinernematidae

Rhabditina

Rhabditoidea

Steinernematidae Chitwood & Chitwood, 1937

 

Obligate insect parasites. Infective juveniles carry symbiotic bacteria in the bacterial chamber of the intestine. Sexually reproducing (Nguyen and Smart, 1996).           
   
Unlike in the genus Heterorhabditis, the first generation of adults in the Steinernematidae (Steinernema and Neosteinernema) developing from the IJs are amphimicitic, not hermaproditic; they reproduce sexually. Subsequent generations of adults are also amphimictic.
