TaxID: 409481
Basic Information
Aphelenchoides ritzemabosi
Chrysantenbladaaltje, Stem and Bud Eelworm
Aphelenchoides ritzemabosi (black currant nematode, chrysanthemum foliar nematode, chrysanthemum leaf nematode, chrysanthemum nematode, chrysanthemum foliar eelworm) is a plant pathogenic nematode. It was first scientifically described in 1890 in England. This nematode has a wide host range. Among the most important species affected are Chrysanthemums and strawberries. A. ritzemabosi is a migratory foliar feeding nematode. It can feed both ectoparasitically and endoparasitically, with the later causing the most significant damage. When adequate moisture is present, this nematode enters the leaves and feeds from inside the tissue. Typical damage is characterized by necrotic zones between the veins of the leaves. Its lifecycle is short; only ten days from egg to mature adult. A single female can lay as many as 3,500 eggs. This pest can be difficult to control. Host plant resistance, hot water treatments, and predatory mites are recommended.

Morphological Features
Females slender, 0.8–1.3 mm long. Body annulation fine and distinct. Lateral field with four lines. Lip region slightly expanded, hemispherical, with distinct constriction. Stylet slender with small but distinct basal knobs. Pharynx with tubular procorpus, elongate-ovoid median bulb, and long esophageal glands overlapping intestine dorsally for 5–6 times body width. Nerve ring located 1–2 body widths behind median bulb. Ovary single, anteriorly outstretched, often extending to anterior 1/3 of body; oocytes in multiple rows. Post-uterine sac broad, sac-like, more than half of vulva–anus distance, often containing sperm. Tail conical with pointed terminus, bearing a star-shaped mucro; tail length about 3× anal body diameter. Males 0.9–1.2 mm long; tail curved ventrally; without bursa; spicules paired, needle-like.
