Onion & Western
Flower Thrips

Thrips tabaci
Frankliniella occidentalis

Symptoms:
Thrips are small, elongate clear-bodied insects most often found scurring about in opened flowers. Direct plant damage from thrips is minimal (except on onions), but they are known to readily transmit viruses. Thrips are ubiquitous pests of ornamental and weed species where they are never controlled. They also may be found on small grains that are frequently used as wind breaks.
