Frankliniella occidentalis (Pergande) and Frankliniella intonsa (Trybom) are sympatric pests of many greenhouse and field crops in Korea. Life cycle and appearance of Western flower thrips. Short distance spread is by flight; thrips are weak fliers, but often assisted by wind. Life Cycle: A life cycle, from oviposition to adult emergence, may require two weeks in warm weather, to about six weeks in cool weather. Furthermore, the estimated crop damage by all tospoviruses transmitted by western flower thrips exceeds US$1 billion per year. The Situation: In southern California, the native western flower thrips (WFT) Frankliniella occidentalis is the most common vector responsible for transmission of an exotic plant virus, Tomato Spotted Wilt Virus (TSWV).The pathogen was discovered on tomatoes in 1915 in Australia, and has been spreading around the world ever since. They begin feeding immediately after hatching. wings. Frankliniella occidentalis (Pergande) and Frankliniella intonsa (Trybom) are sympatric pests of many greenhouse and field crops in Korea.

Clipboard, Search History, and several other advanced features are temporarily unavailable. The western flower thrips (Frankliniella occidentalis) develops in six stages: egg, two larval instars, prepupa, pupa, and finally the adult insect. Thrips are economically important since some species transmit plant viruses. In the Netherlands, for instance, the annual cost of western flower thrips was put at US$30, with another US$19 million for TSWV. Identification. Asia, North, South and Central America, the Caribbean, Europe, Oceania. NATURAL ENEMIESNatural enemies include Orius, Geocoris and Nabis species and also the larvae of lacewings, but all these are general predators.

At 15°C, pre-oviposition time is longer (10.4 days) than at higher temperatures of 20 or 30°C (2-4 days). The eggs are inserted into soft plant tissues, including flowers, leaves, stems and fruit. Direct damage results in lost yield and/or inferior prices, as damage is unsightly - common in roses, strawberries, beans, capsicum and cucumbers. Larvae emerge and begin to feed on the plant. Use yellow or blue sticky traps placed about 10 cm above the crop, and inspect weekly. © The Authors 2015. The length of the life cycle and life expectancy of the adults depends on temperature and also on the quality of the food. The intrinsic rate of natural increase (rm) was higher at constant temperature than at fluctuating temperature for both thrips species. RESISTANT VARIETIESThere are resistant varieties of cucumber and tomato to TSWV. The eggs hatch in 2 to 14 days, depending on temperature. Bare ground is also effective. Interestingly, the nymphs have to pick up the virus for the adults to be able to transmit it. ShuQi H, Ying L, Lei Q, ZhiHua L, Chao X, Lu Y, FuRong G. Environ Entomol.

Western flower thrips (WFT), Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) is a native insect of the western part of North America that was first reported in 1895.In the 1970s and early 1980s, this species spread throughout North America (Beshear 1983). Western flower thrips, Frankliniella occidentalis, first arose as an important invasive pest of many crops during the 1970s–1980s.The tremendous growth in international agricultural trade that developed then fostered the invasiveness of western flower thrips. Summary. PLoS One.

Effect of temperature on infection, development and reproduction of the parasitic nematode Thripinema nicklewoodi in Frankliniella occidentalis. Exp Appl Acarol. Thrips display parthenogenesis (reproducing without mating), and both mated and unmated females can lay eggs. Direct damage results from feeding. Worldwide. Grasses, however, are poor hosts and could be used around greenhouses and nurseries to reduce the need for management of other weeds that are hosts. However, time from egg to adult depends on temperature, with the optimum range between 26 and 29°C (79 and 84°F). It is essential that the underside of leaves and terminal buds are sprayed thoroughly since these are the areas where the thrips congregate. Blue traps have  |   |  United States: Florida, Georgia, Hawaii, Louisiana, and Texas. Both are less than 1.5 mm long and are best identified with a hand lens or microscope. This means that once the thrips picks up the virus through feeding, it retains it for life. Published by Oxford University Press on behalf of Entomological Society of America. DAMAGE. Use insecticides as follows, but note that frequent use of broard spectrum synthetic insecticides may also lead to development of insecticide resistance in thrips populations: AUTHOR Grahame JacksonPhoto 1 T Smith, University of Massachusetts.Bugwood.org. Life cycle can vary between 13 and 40 days dependent on temperature. Indirect damage by thrips as a vector of TSWV is common in lettuce, capsicum and tomato. The life cycle consists of five stages: egg, larval, prepupal, pupal and adult. Commercial horticultural oil can also be used. The life cycle varies from nine to more than 40 days in Australia, depending on temperature (Diagram). NIH On more than 250 plants in 65 families; these include: ... Frankliniella occidentalis.

Adult male WFT are light yellow, while adult female WFT are a little larger than the males and vary in color from light yellow, yellow with brown splotches, to dark brown. The virus causes significant damage to vegetables in the Solanaceous family, such as tomatoes (Photo 3), potatoes and capsicum, but also lettuce. Check seedlings to ensure that they are free from symptom. First, the insects are hidden within flowers and the leaves of shoots; secondly, the eggs are inserted into the leaves making it difficult for sprays to reach them; and thirdly, thrips rapidly become resistant to insecticides, so much so that there are large differences in the susceptibility of thrips populations to commonly used products. Photo 1. Do not plant new crops next to those infested by thrips; do not plant the same crop on the same land without a break: use a rotation; and do not plant new crops downwind from those infested with thrips. M. Tsompana, J.W. Life Cycle:Females lay eggs in tender plant tissue. Photo 3 William M Brown Jt., Bugwood.org. Second-instar larvae also feed on plant tissue, usually in flowers.

Females can live up to 45 days and lay (oviposit) between 150 Taxonomy Thrips have several generations (up to about eight) a year. TSWV has a very wide host range, and the only thrips that transmits the virus in a persistent way. Also, predatory mites (Transieus and Amblyseius species) and predatory thrips (Haplothrips) are common, but do not adequately control thrips populations, except under greenhouse conditions, where they are used as part of IPM programs. Fankliniella occidentalis. When the weather is warm, the life cycle from egg to adult may be completed in as short a time as 2 weeks.
