Thripidae

Definition

The largest and most diverse family of thrips (order Thysanoptera), characterized by a downward-curving, saw-like ovipositor, narrow wings with only two longitudinal veins, and antennae bearing six to ten segments with forked, stiletto-shaped sense cones on segments III and IV. Members are predominantly plant-feeding and include many economically significant agricultural pests.

Etymology

From Thrips (type genus) + -idae (family suffix)

Example

The onion thrips (Thrips tabaci) and western flower thrips (Frankliniella occidentalis), both members of Thripidae, are among the most destructive thrips pests of vegetable and ornamental crops worldwide.

Usage Notes

Thripidae is distinguished from the other major thrips family Phlaeothripidae by its saw-like (terebra-like) ovipositor and reduced wing venation; Phlaeothripidae typically possess a tubular, upturned ovipositor and often have broader wings with more veins. The family comprises four recognized subfamilies: Thripinae, Dendrothripinae, Sericothripinae, and Panchaetothripinae. Common genera include Thrips, Frankliniella, Taeniothrips, and Anaphothrips. The name is sometimes misspelled 'Thysanoptera' in error; proper usage maintains the family ending -idae.
