Bu çalışma Mersin İli (Türkiye) bağ alanlarında bulunan thrips (Thysanoptera) türlerinin tespiti, popülasyon değişimleri ve zarar oranlarını belirlemek amacıyla 2019 2020 yıllarında yürütülmüştür. Çalışma sonucunda 14 Thysanoptera türü belirlenmiştir. En fazla tespit edilen tür Rubiothrips vitis (Priesner, 1933) (Thysanoptera: Thripidae) (%56) olmuş onu Mycterothrips tschirkunae (Yakhontov, 196...

In 1996, Scirtothrips perseae Nakahara (Thysanoptera: Thripidae) invaded California avocado orchards and moved pest management practices that relied almost exclusively on biological control to strategies dependent on insecticides to maintain thrips densities below economically damaging levels. By 1998, average losses due to thrips feeding damage in untreated infested groves reduced industry rev...

A key is provided to five Old World species that comprise the genus Ceratothripoides Bagnall, and the species C. revelatus (Priesner) is recalled from synonymy with C. brunneus Bagnall. Five New World species previously placed in this genus are here allocated to Retanathrips Mound & Nickle gen.n., with Physothrips funestus Hood as type species.

Onion thrips (Thrips tabaci Lindeman (Thysanoptera: Thripidae)) can be a pest in organic onion production on Prince Edward Island. This study was to examine the effect of planting time and variety on infestation levels and damage by onion thrips on cabbage (Brassicae oleracea capitala (L.)). A field site was planted with 2 main and 8 lesser varieties of cabbage over 4 planting dates. Some varie...

Earlier studies have shown that Tomato spotted wilt virus (TSWV) influences the biology, performance, and behavioral patterns of its vector Frankliniella occidentalis Pergande. In this study, using Capsicum annuum L. as the host plant, we aimed to determine the manipulation of F. occidentalis by TSWV through switching of the diet (+ or -TSWV) during vector's development. Behavioral patterns, fi...

Both orchard and adjacent native vegetation harboured adult western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), from early spring until fall. Frankliniella occidentalis made up the great majority of adults collected in flowers of most plant species sampled, including apple. Other species found on apple flowers included Anaphothrips obscurus Müller, which live...

Species of the genus Chirothrips Haliday breed and pupate only within grass florets. Each larva is restricted to a single floret, and adult body size is thus presumably related to floret size. Despite this, some Chirothrips species are distinguished only on states that are related to body size. The validity of some commonly recorded members of the C. manicatus species-group, including C. africa...
