| Abstract: | The internal morphology of the western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) (WFT), a primary vector of tomato spotted wilt virus (TSWV), was shown to bear certain similarities to other thrips species, particularly in the composition of the piercing-sucking feeding structures. Striking differences were observed in number, position and ducting of the salivary glands, the morphology of the alimentary canal and the number and arrangement of the malpighian tubules between the WFT and other studied Thysanopterans. These differences provide support for the conclusion that internal morphologies may vary widely in this order, and perhaps among species in the same genus. The results of our investigation support the need for more detailed studies of other thrips species, particularly in light of the potential importance morphological characteristics may play in governing the capacity of thrips species to serve as vectors of TSWV. |
