Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type)
Description: Thrips feeding usually follows minor veins and the overall appearance is similar to some diseases like etch. Heavy feeding will sometimes give the surface of the leaf a shiny or silvery appearance. The underside of midribs may also be injured. Damage is most common on lower leaves of knee-high plants, but thrips may attack newly set plants. Adult thrips are tiny (1/25 inch), elongate insects, dark brown with featherlike wings. Immature are smaller and yellow or yellow-orange. To see thrips, slap a damaged leaf against a light-colored surface and observe insect movement on that surface. Thrips may be most significant as a vector of tomato spotted wilt virus.
