Callococcithrips gen.n. is erected for the species Rhynchothrips fuscipennis Moulton that lives only among the protective waxy secretions of an eriococcid on Kunzea in south-eastern Australia. Larvae and adults of this thrips move rapidly amongst the sticky wax strands, and their maxillary stylets are unusually long and convoluted. Circumstantial evidence suggests that the thrips is predatory o...

The purpose of the study was to identify forage plants and specialized entomophages wheat thrips in agrocenoses winter spring grain crops cultivated Samara region. highest number adult pests noted (2365.0 ind./100 strokes), lowest barley (565.0 strokes). Egg laying by thrip females occurred on all crops. Larvae were ears wheat, triticale, barley, with exception barley. During research, two iden...

It has been shown that many insects have Enterobacteriaceae bacteria in their gut system. The western flower thrips, Frankliniella occidentalis Pergande [Thysanoptera: Thripidae], has a symbiotic relation with Erwinia species gut bacteria. To determine if other Thripidae species have similar bacterial symbionts, the onion thrips, Thrips tabaci, was studied because, like F. occidentalis, it is p...

During November 2021, a new invasive thrips Thrips parvispinus was recorded in chilli growing areas of Telangana state. In India, this pest first reported on papaya (Carica L.) and later Brugmansia sp. (Solanaceae) Dahlia rosea Cav. (Asteraceae). Based these reports alert received from ICAR-NBAIR, Bengaluru, survey carried out major Anand district Gujarat Incidence T. noticed during the survey....

Sexual dimorphism is a phenotypic differentiation between males and females of the same species. Thrips display a wide variety of sexual dimorphism between taxa including size, ornamentation and coloration (Crespi 1986, Mound 2005, Tyagi et al. 2008). During recent surveys on the thrips fauna in subtropical China, Aroidothrips longistylus Ananthakrishnan, an interesting and little known sexuall...

The thrips Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) is an invasive pest that poses a significant economical threat to U.S. agriculture and trade. In this study, DNA sequence data and polymerase chain reaction (PCR) were utilized to develop a molecular diagnostic marker for S. dorsalis. The DNA sequence variation from the internal transcribed spacer 2 (ITS2) region of nuclear ribosom...

The prey preference of polyphagous predators plays an important role in suppressing different species of pest insects. In this study the prey preference of the predatory mite, Amblyseius swirskii (Athias-Henriot) (Acari: Phytoseiidae) was examined between nymphs of the twospotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) and first instar larvae of the western flower thrips, F...

Field trials were laid in the farmer’s holdings at Kaalipalayam, Coimbatore district during August, 2011 to November, 2011 to assess the efficacy of selected botanical insecticides against aphids, thrips, leaf miners and defoliators infesting Solanum nigrum. The results of the experiments revealed that among the treatments, foliar spray of profenophos is found to be the best treatment for the m...

Thrips tabaci Lindeman is a global pest and also represents serious threat to onion production in Poland. In 2 years (2015–2016) of field studies, 8 cultivars were evaluated characterize their susceptibility thrips determine if leaf colour associated with preference. The actual count the proportional abundance adult collected from leaves during plant colonization by insects both used express pr...

Tomato spotted wilt virus (TSWV) causes sporadic but serious disease in Australian potato crops. TSWV is naturally spread to potato by thrips of which Thrips tabaci is the most important. Prior studies indicated possible non-preference of potato cultivars to T. tabaci. Select potato cultivars were assessed for non-preference to T. tabaci in paired and group choice trials. Cultivars 'Bismark', '...
