scientific name    Sericothrips    

Grasses, clover (Jacot-Guillarmod, 1971), buffaloberry, various weeds (Chiasson, 1986).


The head is wider than long and ocelli are present on a slightly raised portion of the head. The interocellar setae are short. The antennae are 8 segmented, and segments 3 and 4 each have a forked sense cone. On the prothorax there is one pair of moderately developed posterior angular setae. The pronotum is sculptured with either hexagonally reticulate lines or transverse striae. The mesosternum and metanotum are sculptured (Stannard, 1968), and both have a furca with a spinula (Mound and Kibby, 1998). The mesospinasternum is separated from the metasternum by a suture. The forewings are narrow with the forevein evenly covered with setae, and the hind vein has several to no setae at the apex. The abdominal segments are covered with microsetae, though the segments may be bare medially. Abdominal sternite 7 has major setae in front of the posterior margin. Abdominal tergites 7, 8, and occasionally 9 each have a complete comb of posteromarginal setae. Males may have a small, circular glandular area on each of sternites 4 to 7, or 5 to 7, or just sternite 7, or males may lack glandular areas completely (Stannard, 1968).

life history
Some of the species in this genus are host-specific. Most species in this genus over-winter as adults under bark, fallen logs, in grass, or in plant stems (Stannard, 1968).

This genus has not been reported to cause economically significant damage to crops (Stannard, 1968).

diet info
Members of this genus are leaf feeders (Stannard, 1968).

Sericothrips occur in most parts of the world (Mound et al, 1976).
