For Frankliniella occidentalis (Pergande) in strawberry, counts of thrips in flowers are commonly used as there is a strong correlation between thrips number per flower and fruit damage. This type of damage is less apparent on white or yellow flowers, and these commonly tolerate very much higher thrips populations with no visible symptoms. 0000019445 00000 n F. occidentalis affects commercial plant production in various ways, directly by reducing yield and market quality, whether through feeding damage or by the transmission of virus pathogens, but also indirectly when the mere presence of thrips on a crop is used as a reason for denying it entry to a profitable market. Courtesy: P.M.J Ramakers - PTG, Waaldwijk (NL).
