EntomopathogenicNematodes

Biology of nematodesEntomopathogenic 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 actionOnce released, nematodes actively seek out their insect hosts. When a host has been located, the nematodes penetrate the insect through body open-ings 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 soilFor 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 pop-ulation will decrease quickly.

AquaNemixOur nematodes are formulated in a vermicu-lite or clay powder that should be mixed well in water prior to use. An easy way to apply nematodes is to use AquaNemix. The tank of the AquaNemix holds 1 liter of concentrated nematode stock. The intergrated proportion-ing system mixes the nematodes in a 2% ratio with the irrigation water. AquaNemix has a quick coupler, allowing easy connection to the hose.
