This nematodes species is similar to Steinernema, except that it can also enter its prey through the body wall and body openings.
Nematodes are microscopic, non-segmented worms which occur naturally in soil all over the world.
Thousands of strains exist with different life-styles. Beneficial nematodes only attack soil dwelling insects and leave plants alone. The nematodes enter the host through body openings or by penetration of the body wall. Once inside, they release a bacterium which kills the host within 48 hours. The nematodes continues to reproduce and its offspring begin to seek out new host material.
