What are the thrips in plants?

Thrips, very tiny, cigar-shaped insects which move from plant to plant are responsible for transmitting the TSWV. Thrips thrive in warm dry springs, thus during hot dry years, we tend to see more thrips and more plants infected with TSWV. Symptoms may appear on plants within a few weeks after infection. Immature thrips feed on infected tissue, and the virus multiplies in their midgut and other organs, and once the thrips become adults, they can subsequently transmit the virus to whatever they feed on for the rest of their lives. Thus, management of TSWV is dependent on reducing thrips, and on selecting TSWV resistant varieties.

TSWV is transmitted by western fl ower thrips. The thrips acquire the virus when they are in the larval stage and are able to transmit it for the remainder of their lives.
