Genus Anguina Scopoli
The type
species, Anguina tritici (Steinbuch, 1799) Filipjev, J936, is the
first authentic record of a plant parasitic nematode. These are
typically gall forming nematodes of aerial parts of plants. A.
tritici is the most important species attacking wheat. Barley is
another host for the nematode, though field occurrence is rare. Amongst
the other species, A. agrostis (Steinbuch, 1799) Filipjev, 1936,
A. graminis (Hardy, 1850) Filipjev, 1936 and A. bahamophila
(Thorne, 1926) Filipjev, 1936, are of some importance.
The ear-cockle
disease of wheat was discovered by a Dutch clergyman, Needham, in 1743s
who first mistook it for smutted grain of wheat, but on examination,
observed larvae within the galls. Subsequently, the causal relationship
between the disease and the worms was demonstrated3. Later,
it was named as vbrio tritici. The other names given during the
course of time were Rhabditis tritici, Angui/ulla tritici, A.
graminearum, Anguilullina tritici, Tylenchus tritici, Anguillula
scandens and Tylenchus scandens the genus Anguina
erected in 1777s was revived in 1936 and the name A.
tritici was established.
