|scientific name Heliothrips |
Pantropical. In temperate regions on plants in greenhouses, houses and malls (Heming).
The head is reticulate with a neck-like constriction at the base. The eyes are large and protruding, and the ocelli are on a raised area between the eyes. The antennae are 8 segmented. Antennal segment 3 is elongate, segments 7 and 8 form a style, and segment 8 is about 4 times as long as 7. Antennal segments 3 and 4 have simple sense cones. The prothorax is reticulate, and all the setae are small. There is a V-shaped reticulate area medially on the metathorax. The mesospinasternum is fused to the metasternum, and the tarsi are 1 segmented. Both sexes are macropterous. The forewings bulge at the base, and the forevein is fused to the costa. The leading edge of the forewing lacks bristle-like setae. The abdominal tergites are hexagonally reticulate along the sides, and somewhat along the meson. Abdominal sternites lack accessory setae, and the marginal setae are anteriad of the posterior margin. Tergite 8 has a complete comb of setae. The ovipositor is well developed in females, and males have one transversely elongate glandular area on each of sternites 3 to 7 (Stannard, 1968).
Only 2 species are currently known to belong to this genus (Wilson, 1975; Mound and Marullo, 1996).
Host plants (Heming).
Tropics, and subtropics, South Africa (Mound et al., 1976), and worldwide in greenhouses (Mound and Marullo, 1996).
