Citrus nematode females are

Citrus nematode females are Cocci shaped.
Tylenchulus semipenetrans, also known as the citrus nematode or citrus root nematode, is a species of plant pathogenic nematodes. Their feeding strategy is semi-endoparasitic and has a very narrow host range among commonly grown crops.
The posterior end of the female citrus nematode becomes swollen upon feeding. She contains a single ovary and the vulva is subterminal. The female will lay up to 100 eggs deposited in a gelatinous matrix secreted from the nearby excretory pore. The pore is surrounded by small, irregularly shaped lobes; and the excretory duct is directed forward.
