Hirschmanniella spinicaudata (Schuurmans Stekhoven, 1944) Luc & Goodey, 1964

Morphology and Anatomy:

Reported median body size for this species (Length mm; width micrometers; weight micrograms) - Click:

Distribution:

Sher found complexes of several species in collections from rice, including H. spinicaudata and H. belli. Literature prior to 1968 may deal with mixtures.

Feeding:

Migratory endoparasite of roots. Juveniles and adults enter behind the root tip and move in air channels; can also migrate into older roots.

In West Africa, H. spinicaudata can reduce rice yields by 20%, and can survive the dry season well in root debris; however, if the fields are flooded between crops, causing the roots to decay, hydrogen sulfide is released and H. spinicaudata survives poorly (research by Fortuner in Senegal).

But flooding may be difficult to achieve as river flow diminishes during the dry season, making water less available.
