In contrast to most other thrips species, chilli thrips complete their entire life cycle on the plant. In general, the life cycle (egg to adult) takes two to three weeks to complete. J Insect Sci. Females of Frankliniella schultzeiinsert their eggs in flower tissue. It is essential that the underside of leaves and terminal buds are sprayed thoroughly since these are the areas where the thrips congregate. The eggs of the western flower thrips (Frankliniella occidentalis) are laid in … Western flower thrips, Frankliniella occidentalis, first arose as an important invasive pest of many crops during the 1970s–1980s. Photo 3. Life Cycle: A life cycle, from oviposition to adult emergence, may require two weeks in warm weather, to about six weeks in cool weather. Some countries have produced figures for the estimated costs of western flower thrips and TSWV. For Permissions, please email: journals.permissions@oup.com. Adults have two sets of narrow, clear, nearly veinless wings that have dark, hairy, fringes. Bare ground is also effective. Frankliniella occidentalis is a pest of several crops throughout Florida and the world and is capable of causing economic loss (Fig. The development time from egg to adult of F. intonsa was shorter than that for F. occidentalis at both constant and fluctuating temperatures. Diagram Life cycle western flower thrips. Impact of constant versus fluctuating temperatures on the development and life history parameters of Tetranychus urticae (Acari: Tetranychidae). 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.
