DSSSB PGT - 2023,
Answer: A
Tylenchulus semipenetrans is the citrus nematode, which causes slow decline of citrus by feeding on the roots with the front part of its body embedded in them.
The root-knot nematode is Meloidogyne, the ear cockle nematode is Anguina tritici, and the burrowing nematode is Radopholus similis.
The citrus nematode is a semi-endoparasite: the female pushes the front end of her body into the root and feeds from a few cells. Heavy infestation causes the slow decline of citrus trees, with thin foliage and small fruit.
