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. Questo nematode si muove attivamente nel terreno in cerca di larve ospiti. Much of the previous research concerning H. More than 2species of pest insects from 1insect families are susceptible to these beneficial nematodes.

Eggs laid by the hermaphrodites produce . The reason: these nematodes boast a deep-moving (1-7″), active-hunting, “cruising” characteristic which make them . The beneficial nematodes we sell are parasitic to insect pests that typically have a . It is used to control black vine weevil larvae in ornamentals and berries.

It is also used for curative chafer grub control in turf. Common name, Entomopathogenic nematode. The mass release of these nematodes provides an efficient and curative control of key insect pests in a wide range of crops.

This nematode is widely distributed in North and South America, Australia, and Europe, but has many strains that differ in behavior and physiology. The parasite being featured today is one of a handful of parasitic nematodes that you can purchase from your local gardening supplies store. There microscopic worms, called entomopathogenic nematodes ( EPN), are commonly used by both farmers and gardeners as a . Forstorage at controlled conditions (temperature, pH andosmolarity), aerated water is superior to all othermethods tested and the addition of preservatives willincrease survival.

As the tools available for these tasks improve, it is useful to return to data produced with earlier instances to assess their credibility and correctness. Females: Head truncate or slightly rounded. Labial region with six distinct protruding lips surrounding the mouth with six labial papillae on tops.

Amphids located posterior to labial papillae (FIG.1).

All the other stages exist only inside the insect host. The infective third-stage juveniles move through the soil in search of a host. TT0 kayaii, thracensis.
