Thrips (Order Thysanoptera) are ubiquitous, small to minute (a few millimeters long) and slender-bodied insects with fringed wings. The morphology is reduced: thrips have only one functional mandibular stylet, the second being greatly reduced, thus forming asymmetrical suctorial mouthparts compacted within a short cone-shaped rostrum. About 50% of the known species of Thysanoptera feed on fungi, approximately 40% feed on living tissues of dicotyledonous plants or grasses, and the remainder exploit mosses, ferns, gymnosperms, cycads, or are predatory (Morse and Hoddle 2006). Less than 1% of described thrips species are serious pests and most economic literature deals with just four species (Mound and Teulon 1995).
