Solution(By Examveda Team)

Citrus tristeza virus is Semi persistent.
Citrus tristeza virus (CTV) is transmitted by several aphid species in a semi-persistent manner with Toxoptera citricida, the brown citrus aphid (BrCA), being the most efficient.
Citrus tristeza virus (CTV) belongs to the Closterovirus genus, which potentially caused an economic loss in citrus plants and produces subgenomic noncoding RNAs called LMT1.
