Haplothrips
Haplothrips is a genus of thrips in the family Phlaeothripidae. It is found worldwide and contains about 240 extant species.
Description
Thrips of this genus are medium-sized with one pair of 8-segmented antennae, three pairs of legs and usually two pairs of well-developed wings. The head has a short mouth cone and a pair of deeply retracted maxillary stylets. The forewings are distinctly constricted in the middle and have duplicated cilia. The second through to the seventh abdominal tergites each have two pairs of sigmoid wing-retaining setae. In males, the ninth abdominal tergite has setae S2 short and stout, while the eight abdominal sternite usually has no pore plate. The male of H. dissociatus is unusual in having a small pore plate.Some of the aforementioned features, such as the forewing constriction, are shared by other Haplothripini.
Ecology
Haplothrips mostly feed and breed in flowers. The northern hemisphere species prefer flowers of Asteraceae and Poaceae, while the Australian species feed on a range of families. Some species are instead associated with leaves.Other Haplothrips are predatory. Examples are H. faurei and H. victoriensis, which are used in biological control of mites.
The Hawaiian species H. rosai is believed to feed on fungi.
