To avoid misunderstand-ings and misinterpretations, it is clear that the term “host plant” must be applied in the proper context. The egg is cylindrical and slightly kidney shaped. Several species of thrips can infest greenhouse floral crops, but the most severe and common pest in recent years has been the western flower thrips (WFT), Frankliniella occidentalis. Western flower thrips, Frankliniella occidentalis, feeds in a piercing sucking manner and is a worldwide pest on many ornamental and vegetable crops. Western flower thrips can damage flowers, such as roses, with petal discoloration as a result of thrips feeding. Life stages Egg. Heavily infested flower buds may not open at all, and fruit can be damaged, even with low thrips populations. to select for host plant resistance or tolerance . Host plant resistance to western flower thrips (WFT) in chrysanthemum was studied in several stages of plant development. The western flower thrips (Frankliniella occidentalis) is the most important vector for both tomato spotted wilt virus (TSWV) and impatiens necrotic spot virus (INSV). On avocados, thrips can cause brown or silver scarring on the fruit. WFT damage plants directly by feeding, and indirectly by acting as vectors for the tospoviruses impatiens necrotic spot virus (INSV) and tomato spotted wilt virus (TSWV). This generally occurs in the compost or soil below the plant on which the larvae fed. TSWV has a very wide host range, and the only thrips that transmits the virus in a persistent way. Thrips palmi was first described by H. Karny in 1925 from specimens collected in 1921 on tobacco in Sumatra. Western flower thrips will … Female adult western flower thrips of different age were randomly collected with a small aspi- Management. HOSTS. Onion thrips and western flower thrips are found widely throughout New Zealand on a broad range of crops. The number of WFT on non-flowering plants was significantly lower than on flowering plants or single cut flowers. Damage. The second most abundant predators were spiders (Araneae). The maxillae then ingest the fluids from the cells, but not directly from the vascular tissue. 106); however, the western flower thrips is the more important vector. As a result, you typically see the damage they cause well before seeing the insects themselves. Western flower thrips also vector some potentially devastating diseases, such as Impatiens necrotic spot virus or Tomato spotted wilt virus . TSWV is a tospovirus spread by western flower thrips, onion thrips (see Fact Sheet no. western flower thrips. The behavioural responses of adult female western flower thrips, Frankliniella occidentalis (Pergande) to volatiles from meadow-sweet (Filipendula ulmaria), bay laurel (Laurus nobilis) and sage (Salvia officinalis) were investigated in laboratory bioassays. On leaves thrips can ingest the cell contents of Large numbers of young flush leaves were killed which negatively impacted ACP, as ACP is dependent on flush for oviposition and nymph development. The western flower thrips were originally from the western US, but began to spread in the 1960s and are now a global pest. Western flower thrips (WFT) Frankliniella occidentalis continues to be a serious pest of floriculture crops in New England. Plant length and leaf area of non-flowering Dendranthema grandiflora Tzvelev were reduced after WFT infestation, and these two variables were correlated. Western flower thrips, the primary thrips species encountered by greenhouse producers, is extremely polyphagous, feeding on a wide-variety of horticultural crops grown in both commercial and research greenhouses. Rearing of Western Flower Thrips.A culture ofF. Western Flower Thrips. Small spider immatures (first and second instars) of several species were common on certain host plants, and are likely to feed on WFT. Western Flower Thrips John P. Sanderson Introduction. Successful IPM programmes for management of western flower thrips (WFT), Frankliniella occidentalis, on UK strawberry crops have been developed using knowledge of its biology and behaviour (Bennison The objective of this study was to investigate quantitative host plant resistance to thrips in carrot and to identify candidate compounds for constitutive resistance. One hundred thirty species of native and introduced plants growing in uncultivated land adjacent to apple and pear orchards of central Washington and northern Oregon were sampled for the presence of the western flower thrips (WFT) Frankliniella occidentalis (Pergande, 1895) and potential thrips predators. Onion thrips (Thrips tabaci), top, and western flower thrips (Frankliniella occidentalis), bottom are typical thrips, none to easy to tell apar! The female makes an incision into the leaf, stem or fruit of plants with her serrated ovipositor and deposits a single egg. Both viruses affect a wide range of plants, and often a single host plant may be infected by both viruses. Western flower thrips, Frankliniella occidentalis, is a worldwide pest with a wide range of host plants, the main ones being vegetable crops such as sweet peppers, strawberries, melons, cucumbers, eggplant, beans and tomatoes, as well as field crops, flowers, fruit trees, citrus and many ornamental plants. Host Plants: This thrips feeds on almost any flowering plant. α-Ionone decreased the number of eggs laid by female thrips on wild-type leaves (Figure 4; p < 0.005, t = 2.56, df = 18). The western flower thrips [Frankliniella occidentalis (Pergande)] is an invasive pest insect in agriculture. Western flower thrips feeds on apple, apricot, peach, plum, nectarine, orange, lemon, alfalfa, potato and numerous weed species. The western flower thrips (Frankliniella occidentalis) is the most important vector for both tomato spotted wilt virus (TSWV) and impatiens necrotic spot virus (INSV). Western flower thrips, Frankliniella occidentalis P. (Thysanoptera: Thripidae) is a major agricultural and horticulture pest worldwide (Kirk, 2002; Kirk and Terry, 2003).It causes damage and spoilage to a vast number of economically important plant species through feeding, oviposition and spread of several plant diseases, most notably tospoviruses (Morse and Hoddle, 2006). Introduction . It was collected on 64 plant species, all of which were hosts for WFT. The platform was used to establish host-plant preference of thrips with a large plant population of 345 wild Arabidopsis accessions (the Arabidopsis HapMap population) and the method was optimized with two extreme accessions from this population that differed in resistance to thrips. Based on pesticide resistance studies, western flower thrips has various metabolic detoxification enzyme systems that could help it to overcome secondary plant defenses (Jensen 2000; Espinosa et al.
