Statistische Signalverarbeitung,virus diseases mainly in the tropical and subtropical countries. Many of the whitefly transmitted viruses cause yellow or golden mosaic or leaf curl symptoms. Whitefly transmitted viruses have non-persistent, semi-persistent and persistent relationships.

In majority of the cases especially ilarviruses (passively) and tospoviruses transmitted by thrips cause necrotic symptoms in affected plants.

Mealybugs are sluggish insects that transmit viruses in semi-persistent manner. They are known to transmit ampelo, badna and clostero genera of plant viruses.

Statistische Signalverarbeitung,s. Beetles (Fam: Chrysomelidae) have the biting type of mouth parts and lack salivary glands. Plant viruses in the genera, . and . are transmitted by beetles. More than 74 species of beetle are known to transmit viruses which infect economically important vegetable and grain crops. Beetles transmit approximately 11% of the insect-borne viruses.

Transmission Through Dodder,The stems of these plants wind around other plants with haustoria which connect with vascular tissue of the host and facilitate transmission of the virus from the infected to healthy plants. The dodder can be used for experimental transmission of viruses under controlled conditions.

Transmission Through Seeds,ance spread of viruses. Unlike vectors, infected seeds can be carried away to distant places where they act as primary source of inoculum for spread of a virus. A few of the seed-borne viruses may be carried as surface contaminants while others are carried through embryo considered as true seed-borne viruses.
