Simple In Vivo Production and Storage Methods for Steinernema carpocapsae Infective Juveniles.

Methods are described for standardized in vivo production, rapid harvest, and storage, in a concentrated form, of infective juveniles of the entomopathogenic nematode, Steinernema carpocapsae Mexican strain Kapow selection. Nematodes were stored in nematode wool configurations, consisting of mats of intertwined infective juveniles. Freshly harvested nematodes are readily available in adequate quantities for laboratory and small-scale field evaluations as well as cottage industry production.
