A key to six species of Anaphothrips known from China is provided, together with distribution information. Anaphothrips dentatussp. n. is described and illustrated from Sanjiang Plain in northeastern China, based on one male and five apterous females. This species is unusual in having the posterior margin of tergite VIII with a craspedum of small teeth rather than long microtrichia.

J. Econ. Entomol. 80(5): 1051-1056 (1987) ABSTRACT Data collected in 1983 from six commercial onion fields in upstate New York indicate that dispersion characteristics of onion thrips (OT), Thrips tabaci Lindeman, are precisely described by Taylor's power law (S2 = amb), with Ina = 0.517, SIn, = 0.059, b = 1.89, and Sb = 0.028 (n = 47; r2 = 0.99: P :$ 0.0001). Additionally, during the main peri...

Seeking to identify thrips species associated to peach and the injuries they cause, plants of Aurora and Tropic Beauty cultivars were weekly monitored, from May to August of 2005, in Holambra II district, in Paranapanema, SP. Flowers and fruits from six plants per hectare were sampled by the hitting technique. Frankliniella occidentalis (Pergande), F. schultzei (Trybom), F. gardenia (Moulton), ...

Frankliniella occidentalis is the key vector responsible for the emergence of Tomato spotted wilt virus as a global threat to agriculture. Frankliniella bispinosa is a common thrips in Florida, the Bahamas, and Bermuda, but the role of F. bispinosa in the epidemiology of the virus is not known. The purpose of this study was to determine the ability of F. bispinosa to acquire and transmit Tomato...

Citrus thrips, Scirtothrips citri (Moulton), is a plant-feeding pest most widely recognized for causing damage to citrus and mango fruits. This insect has broadened its host range to become a significant pest of commercial blueberries grown in the San Joaquin Valley of California. We evaluated Beauveria bassiana (Balsamo) for control of citrus thrips in blueberries grown under two watering regi...

Abstract AC303,630 (chlorfenapyr), a member of a new class of compound known as the pyrroles, is a broad spectrum insecticide/acaricide on many economically importance crops. AC303,630 is highly active by ingestion, posesses contact activity and provides moderate residual activity on plants. Extensive field study in many Asian countries has shown AC303,630 to be highly effective on many economi...

Peanuts receive major emphasis because of the crop's importance to the economy of southeastern Virginia and the magnitude of pesticide use in crop management. In 1992, growers planted 93,000 acres of the crop and harvested an estimated 123,225 tons of peanuts with a value of ca. 79 million dollars in farm income. When coupled with the shelling, processing and shipping industries in the Tidewate...

Thripenema fuscum n. sp., a parasite of the tobacco thrips, Frankliniella fusca, is described and illustrated from material collected from peanut (Arachis hypogaea) in Marianna, Florida. Thripenema fuscura can be distinguished from all other previously described Thripenema spp. by the dorsal curvature of the male and the presence of a stylet in the male. Highest parasitism rates of F. fusca by ...

Development of insecticide resistance in onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), populations in onion (Allium spp.) fields and the incidence of the T. tabaci transmitted Iris yellow spot virus have stimulated interest in evaluating alternative management tactics. Effects of straw mulch applied in commercial onion fields in muck areas of western New York were assessed in ...

A natural population of thrips, the insect order Thysanoptera, rarely comprises more than 30% males (Mound 2005), and this situation is particularly obvious in the family Aeolothripidae (Mound 1992). Thus for 46% of species of Aeolothripidae in Britain the male is not known (Mound et al. 1976). Aeolothrips is the most species-rich genus in this family, and males are not described for many speci...
