Scirtothrips dorsalis, the chilli thrips [derivation 1] or yellow tea thrips, is an extremely successful invasive species of pest-thrips [1] which has expanded rapidly from Asia over the last twenty years, and is gradually achieving a global distribution. It has most recently been reported in St. Vincent (2004) Florida (2005), Texas (2006), and ...

Sawfly larvae, which are particularly a problem for roses, feed on leaves with a chewing mouthpart that causes "window-paning," an effect that happens when insects eat the material between leaf ...
They are polyphagous as they feed on a wide range of different fruits and ornamental plants. [6] [7] [10] Ornamental plants that they infest are the azaleas, calla lilies, chrysanthemums, fuchsia, roses [5] and orchids. [6] They also are considered pests to ferns, [8] palms and vines and vegetative plants as well. [15]
This process leaves cells destroyed or collapsed, and a distinctive silvery or bronze scarring on the surfaces of the stems or leaves where the thrips have fed. [16] The mouthparts of thrips have been described as “rasping-sucking”, [17] “punching and sucking”, [11] or, simply just a specific type of “piercing-sucking” mouthparts. [18]
The adult common blossom thrips is a very small insect with a length of between 1 and 1.6 mm (0.04 and 0.06 in). There are two colour morphs, a dark form and a pale form, each occupying part of the range, with forms of both colours being reported from Egypt, India, Kenya, New Guinea, Puerto Rico, Sudan and Uganda.

The disease is progressive and often fatal. The common name is taken from the progressive silvering of leaves on affected branches.
Articles relating to the Thrips (order Thysanoptera), minute (mostly 1 mm (0.039 in) long or less), slender insects with fringed wings and unique asymmetrical mouthparts. Different thrips species feed mostly on plants by puncturing and sucking up the contents, although a few are predators. Entomologists have described approximately 6,000 species.
