Entomopathogenic nematodes

Entomopathogenic nematodes occur naturally in the environment as parasites of many insect larvae. The mass release of these nematodes provides an efficient and curative control of key insect pests in a wide range of crops.

Mode of action

Once released, nematodes actively seek out their insect hosts. When a host has been located, the nematodes penetrate the insect through body openings and release symbiotic bacteria that multiply and rapidly kill the insect. Subsequently, nematodes feed upon the host and mature into adults, which mate and produce the next generation. The life cycle is completed within a few weeks and hundreds of thousands of nematodes emerge in search of new hosts.

Persistance in the soil. In some species, nematode infected pest larvae turn a characteristic red or brown colour, providing easy identification of activity. When no new hosts are present, the nematode population decreases quickly.
