Entomopathogenic nematodes

Bionema’s range of commercially available beneficial biopesticides, includes entomopathogenic nematodes for the control of insect pests in the Agriculture, Horticulture (including Turf & Amenity) and Forestry sectors.

What are nematodes?

Entomopathogenic nematodes – Heterorhabditis and Steinernema species – occur naturally in the environment as  parasites of various insect species. The mass release of these nematodes provides an efficient and long-lasting curative control of insect larvae for a wide range of crops.

Biological insecticides are revolutionizing the crop protection industry with their non-toxic activity and long persistence in the soil.

How do nematodes protect crops?

Once applied in the field or containers, nematodes actively seek out their insect hosts.
When a host has been located, the nematodes penetrate the insect through natural body openings and release symbiotic bacteria which rapidly multiply and kill the host within 24-48 hours.
The nematodes feed on the host and mature into adults, which  mate and produce offspring inside the host, which go on to infect new insects.
Insect larvae killed by Steinernema and Heterorhabditis turn a characteristic brick-red (right) and yellow/brown (left), respectively, making it easy to identify which predator is working best.
The life cycle is completed in 12-15 days with hundreds of thousands of nematodes emerging in search of new hosts.
The nematode population then decreases slowly in the absence of living hosts.

Entomopathogenic nematode products

Bionema V

Bionema V contains the nematode species Heterorhabditis bacteriophora, which is highly effective against the larval stages of vine weevil (Otiorhynchus sulcatus), and other soil living larvae.

Bionema V cool

Bionema V cool is a new bioinsecticide that provides excellent control of overwintering larvae of vine weevils in ornamentals and berries. Bionema V cool contains a mixture of two nematode species, Heterorhabditis bacteriophora and Steinernema feltiae. It works at temperatures down to 8°C, enabling application whenever the pest is active.
