Thrips tabaci Lindeman (Thysanoptera: Thripidae) adult and larval settling and oviposition on onion ( Allium cepa L.) foliage were investigated in relation to leaf position and leaf length at prebulb plant growth stages under controlled conditions. Westmore GC, Poke FS, Allen GR &Wilson CR (2013) Genetic and host-associated differentiation within Thrips tabaci Lindeman (Thysanoptera: Thripidae) and its links to Tomato spotted wilt virus-vector competence.
Direct Damage Feeding drains underlying cells, leaving air-filled spaces which impart a silvery sheen and cause distortion during growth and reduction in photosynthetic capacity. Palmer JM (1992) Thrips (Thysanoptera) from Pakistan to the Pacific: a review. Thripidae species can usually be found wherever there is vegetation anywhere in the world. (1986) observed that damage by T. tabaci on cotton seedlings in Israel caused proliferation and branching, early damage significantly reducing yields of fibre and seed. Thrips tabaci Lindeman. saccharifera (sugarbeet), Brassica oleracea var. Thrips settling and oviposition parameters were quantified during the light period on the above ground portion of onion plants from the distal end of the bulb or leaf sheath “neck” through the tips of the foliage. Fore wing first vein usually with 4 (varying from 2â6) setae on distal half, second vein with row of about 15 setae.

Antennae 7-segmented. THRIPIDAE, THRIPINAE. specific chemical control recommendations. Register, Oxford University Press is a department of the University of Oxford. Leaves often develop concentric rings or irregular blotches outlined with haloes, and blossoms are discoloured with circular patterns in the pigment.T. Found throughout New Zealand, T. tabaci is common worldwide, although it is rare in the wet tropics. http://www.ozthrips.org/. gemmifera (Brussels sprouts), Brassica oleracea var. Size and Form: Very small. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Edelson et al. Edelson et al. Metanotum irregularly reticulate medially with lines converging to midpoint near posterior margin; median setae short and arising behind anterior margin; campaniform sensilla absent. Multiplex PCR was performed using a cocktail of the four specific-specific primer pairs viz. Males are known in eastern Mediterranean countries and also in New Zealand, but not in Australia (Westmore et al. This is to ensure that we give you the best experience Thrips tabaci Lindeman, 1889: 61 Limothrips allii Gillette, 1893: 15 Thrips communis Uzel, 1895: 176 Thrips annulicornis Uzel, 1895: 177 Thrips pulla Uzel, 1895: 177 Thrips obsoleta Uzel. Feeding damage includes silvering of leaves, but is is also a vector of tospoviruses, particularly potatoes in Tasmania. tabaci does not transmit contemporary TSWV isolates but it remains on the list of accepted vectors due to its former importance as a vector worldwide (Ullman et al., in Lewis, 1997).T.

Fauna of New Zealand 1: 1â113. botrytis (cauliflower), Brassica oleracea var. ).Major crops cited as susceptible to TSWV formerly transmitted by T. tabaci include celery, lettuces, peas, pineapples, potatoes, tobacco, tomatoes and chrysanthemums. http://www.cbit.uq.edu.au/software/pestthrips/default.htm. Based on these limited late season observations, it appears that However, the effect of TSWV on many crops in addition to tomatoes and tobacco (such as potatoes, celery, lettuces, peas, pineapples and chrysanthemums) from the 1930s to the 1980s is well documented (Sakimura, 1962).

Given this wide distribution in south-eastern Asia for many years, and the recognition of the species by the CIE identification service in London for many years, there seems little evidence to support the suggestion from Sakimura et al. (1986) showed that populations of 50 thrips per plant halved yields in Texas, and T. tabaci populations often greatly exceed that level (Harris et al., 1935). More information about modern web browsers can be found at http://browsehappy.com/. Frankliniella fusca represented 86.7% of all thrips on seedlings, while F. tritici was more abundant on terminals (51.6%), squares (57.5%), and flowers (75.1%).
However, it has been found to be the most important vector of the newly discovered Iris yellow spot virus (IYSV) on onion in Brazil (Nagata et al., 1999).

(1986) observed that attack by T. tabaci on cotton seedlings in Israel caused proliferation and branching, early damage significantly reducing yields of fibre and seed.
Presumably it was originally from the eastern Mediterranean area where males occur. Symptoms vary between hosts but usually appear as purple-brown surface blotches or streaks on stems. Published by Oxford University Press on behalf of Entomological Society of America. For further information, we recommend you visit the following resources: Feeding by T. tabaci, and its by-products, and fouling of plant surfaces, are the main problems associated with crop losses. In a field study, the foliage was divided into three equal partitions, i.e., top, middle, basal thirds, and thrips adults by species, primarily Frankliniella fusca (Hinds) and T. tabaci , were collected from each partition to determine if there was a similar bias of all adult thrips toward the base of the plant. The distribution of T. tabaci and F. fusca by time indicated that there was no temporal displacement of thrips species.
