The generic and English name thrips is a direct transliteration of the Ancient Greek word θρίψ, thrips, meaning "woodworm". [4] Like some other animal-names (such as sheep, deer, and moose) in English the word "thrips" expresses both the singular and plural, so there may be many thrips or a single thrips. Other common names for thrips ...
Thrips, insects of the order Thysanoptera, have unique mouthparts in that they only develop the left mandible, making their mouthparts asymmetrical. Some consider thrips to have piercing-sucking mouthparts, but others describe them as rasping-sucking.
The eyes of the greenhouse thrips are in the form of compound eyes and are made up of 65–70 facets and H. haemorrhoidalis have three ocelli. [9] Another unique thing to the H. haemorrhoidalis is that they have asymmetrical mouthcones that contain an anteclypeus, labrum, labium, paired maxillary stylets and an unpaired left mandible that is ...
Rather than being tooth-like, the mandibles of such insects are lengthened into stylets, which form the outer two parts of the feeding tube, or beak. The mandibles are therefore instrumental in piercing the plant or animal tissues upon which these insects feed, and in helping draw up fluids to the insect's mouth.
The Thripidae are the most speciose family of thrips, with over 290 genera representing just over two thousand species. [2] They can be distinguished from other thrips by a saw-like ovipositor curving downwards, narrow wings with two veins, and antennae of six to ten antennomeres with stiletto-like forked sense cones on antennal segments III and IV.
The chili thrips, Scirtothrips dorsalis, is an Asian pest on many crops, including chili peppers, roses, strawberry, tea, ground nuts, and castor bean. The western flower thrips, Frankliniella occidentalis , has recently expanded its range from western North America to large portions of Europe and Asia through the trade of greenhouse plants.
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.
The western flower thrips [Frankliniella occidentalis (Pergande)] is an invasive pest insect in agriculture. This species of thrips is native to the Southwestern United States [ 1 ] but has spread to other continents, including Europe , Australia (where it was identified in May 1993 [ 1 ] ), and South America via transport of infested plant ...
