Vertical Migration of Second-stage Juveniles of as Influenced by Temperature and Host.

Infective second-stage juveniles (J2) of spp. migrate towards host roots, which depends on several factors, including root exudates and soil temperature. Although is a highly virulent nematode that affects major agricultural crops worldwide, there is limited ecological data about it.

Temperature: a driving factor for migration toward different hosts.

The peach root-knot nematode, , is an emerging species and may become a threat to peach growers if contamination and spread are not avoided. The influence of temperature and two plants - tomato () and French marigold () - on the vertical migration of second-stage juveniles (J2) of was studied using 14-cm long segmented soil columns. Plants were transplanted into cups attached to the top of each column.
