Heterorhabditis is a genus of nematodes belonging to the order Rhabditida. All species of this genus are obligate parasites of insects, and some are used as biological control agents for the control of pest insects. They are microscopic, called entomopathogenic nematodes (EPN), and can be purchased at any local gardening supply stores.

I nematodi entomopatogeni, a differenza dei normali nematodi che sono talvolta dannosi alle piante ed agli animali superiori (cani) sono dei parassitoidi che vivono a spese di larve di insetti o quando queste ultime sono prossime a diventare adulte.
