Distribution:

Economic Importance:

Stunt roots, transmit Tobraviruses including Tobacco Rattle Virus, Pea early-browning Virus and Pepper Ringspot Virus.

Tobraviruses are straight tubular particles with two size ranges, 180-210 nm and 45-115 nm. Trichodorus and Paratrichodorus are vectors.

Feeding:
