Tobacco thrips may cause damage to tobacco, especially during dry years. These slender yellow-to-brown insects are about 1/25 inch long. Adults have four very narrow, featherlike wings. Adults and nymphs suck sap from the leaves producing gray to silver feeding marks primarily along the veins of the lower leaves. The leave also become peppered with minute black spots. The underside of midribs may be damaged. Heavy infestations cause the foliage to turn yellow. |

Thrips feeding usually follows minor veins and the overall appearance is similar to some diseases like etch. Heavy feeding will sometimes give the surface of the leaf a shiny or silvery appearance. The underside of midribs may also be injured. Damage is most common on lower leaves of knee-high plants, but thrips may attack newly set plants. Adult thrips are tiny (1/25 inch), elongate insects, dark brown with featherlike wings. Immature are smaller and yellow or yellow-orange. To see thrips, slap a damaged leaf against a light-colored surface and observe insect movement on that surface. Thrips may be most significant as a vector of tomato spotted wilt virus. |

grass thrips |
Anaphothrips obscurus |
Second-instar larvae are yellow with grey markings, medially on the head, two spots laterally on the pronotum, and transversely on tergites IX and X near the posterior margin. Tergite IX bears two pairs of setae with the apices capitate, and the posterior margin of this segment has a row of teeth. Body yellow with brown markings, antenna 9 segments with VI having at least a partial transverse suture Males of A. obscurus are not known; worldwide the species has never been confirmed to be other than parthenogenetic. The females are dimorphic, either fully-winged (macropterous), or short-winged (micropterous or brachypterous). The macropterae are mainly yellow in colour, although the posterior margin of the head has a brown transverse marking, and the anterior tergites are variably shaded with brown; the forewings are slightly yellow, and the distal antennal segments are mainly brown. Micropterous individuals are usually almost clear yellow. The head and pronotum have no long setae, in contrast to most other pest thrips species. The abdominal tergites are completely sculptured medially, and the eighth abdominal tergite has a complete comb along the posterior margin. Found on corn, rice, wheat, and grasses (per CPC). Host and distribution information from Crop Protection Compendium (CPC) and SFO collection Europe, Asia, Africa, Oceania, pacific, Western Hemisphere CPC Damage: Kamm (1971) recorded a 16% reduction in seed yield of bentgrass (Agrostis stolonifera) in Oregon, USA, and added that subsequent damage to the leaves of the plants almost certainly resulted in further yield reduction. In other reports of yield reduction in grasses grown for seed it is clear that A. obscurus is only one of a group of thrips species that are associated with such damage (Zawirska, 1970). Near Beijing in China, Han et al. (1979) noted that A. obscurus caused serious damage to young maize in late spring if large populations had first built up on wheat in spring and then migrated to maize. Rains depressed population size, but drought increased them. |
