Northern root-knot nematode
species of worm
Northern root-knot nematode (Meloidogyne hapla) is a species of vegetable pathogens which produces tiny galls on around 550 crop and weed species. They invade root tissue after birth. Females are able to lay up to 1,000 eggs at a time in a large egg mass. By surviving harsh winters, they can survive in cold climates (hence, the name, Northern).
Hosts and symptoms
Meloidogyne hapla (Northern root-knot nematode) has a wide host range. It is polyphagous and affects over 550 crops and weeds. It feeds on many agricultural and horticultural plants (vegetables, fruits, ornamentals), but few grasses or cereals. A list of known hosts can be found at the bottom of this page.
Symptoms can be seen in the roots, leaves, and the overall growth of the infected plant. In roots, there may be stunting, wilting, and the formation of abnormal growths called galls.
The public source identifies “Northern root-knot nematode” as species of worm. This brief keeps that definition visible, then builds a research path around Northern, root-knot and nematode.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Northern root-knot nematode”, the useful work is to connect “species of worm” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 19, 2025. The linked authority identifier is Q3021544. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
