Type species of the genus; originally described from a single female.
Additional details provided by Loof and Oostenbrink (1968)
Small plant-parasitic nematodes, 0.4mm long.
Reported median body size for this species (Length mm; width micrometers; weight micrograms) - Click:
Type locality: Ukraine. Widespread in temperate regions of the world
In temperate regions this species can cause severe damage to plants in
the families Apiaceae and Brassicaceae, including carrot, celery and cabbage
(Brzeski, 1991; Majic et al., 2017; Schmidt et al., 2020).
A survey on plant-parasitic nematodes in organic vegetable production
areas in Germany detected P. bukowinensis as the second most
frequent species of te genus, after P. projectus
(Hallmann et al., 2007).
Paratylenchus. bukowinensis on carrot and parsley in
Croatia caused similar root-forking symprtoms as those caused by
Meloidogyne hapla, suggesting damage to meristematic cells in the
root tip.(Chalanska et al., 2017; Schmidt et al., 2020).
Extensive studies on the life cycle and host range of P. bukowinensis
in Europe were conducetd by Brzeski and colleageues in the 1970s (Brzeski,
1971; 1976; 1991).
P. bukowinensis appears to become physiologically active at 8C.
Based on that, Schmidt et al (2020) used 8C as the basal temperatude for
degree-day accumulation in studying this species. In those studies, in
experimental conditions of approx. 20ï¿½C, one generation of P.
bukowinensis wwas completed in 3-4 weeks which comparable with the 23
days suggested by Brzeski et al. (1976) for one generation of the nematode
feeding on cabbage.
Paratylenchus. bukowinensis on carrot and parsley in Croatia
caused similar root-forking symprtoms as those caused by Meloidogyne hapla,
suggesting damage to meristematic cells in the root tip.(Chalanska et al.,
2017; Schmidt et al., 2020).
Host Plant Resistance, Non-hosts
Paratylenchus. bukowinensis appears to be unaffected by the
granular contact nematicide fosthiazate (Nemathorin 10 G) (Chałanska
et al., 2017). That may be beause the short life-cycle allows rapid
recovery from the lethal effects of the nematicide.
Schmidt et al (2020) concluded that due to its relatively narrow host
range, P. bukowinensis can be controlled by rotation with non-host
crops, for example, from the families Poaceae, Fabaceae, Solanaceae or
Asteraceae. In any case, susceptible Brassicaceae as cover crops should be
avoided in vegetable production systems to prevent the build-up of damaging
levels of the nematode.
Although population levels decline quite rapidly at first in the absence
of a host crop, Brzeski (1991) noted that the nematode was still detectable
in naturally infested fields after 2 years without host plants.
